Em sistemas que utilizam processamento assíncrono, como chamadas gRPC não bloqueantes, é comum encontrar cenários onde o gerenciamento inadequado de pools de threads pode levar a problemas de desempenho e até mesmo a um OutOfMemoryError (OOM). Um caso típico ocorre quando o mesmo pool de threads é utilizado tanto para enviar requisições quanto para processar as respostas. Isso pode resultar em um acúmulo de tarefas pendentes que consomem toda a memória disponível, causando um OOM.
Esse artigo descreve o problema que eu passei a semana investigando e como podemos atacá-lo! Vamos lá 👊!
## Simulando o problema
Vamos considerar um exemplo onde um FixedThreadPool é utilizado para enviar milhões de requisições a um "fake" cliente gRPC e, simultaneamente, processar as respostas dessas requisições. O código abaixo demonstra como esse cenário pode levar a um OOM:
```java
public class ThreadPoolsOOMExample {
private static final int THREAD_POOL_SIZE = 10;
private static final int TOTAL_TASKS = 1_000_000;
private final ExecutorService mainExecutor = Executors.newFixedThreadPool(THREAD_POOL_SIZE);
public static void main(String[] args) {
ThreadPoolsOOMExample example = new ThreadPoolsOOMExample();
example.run();
}
public void run() {
for (int i = 0; i < TOTAL_TASKS; i++) {
mainExecutor.submit(this::submitRequest);
}
}
private void submitRequest() {
// Simula o envio de uma requisição para o cliente gRPC
CompletableFuture<Response> future = asyncGrpcCall();
// Processa a resposta usando o mesmo executor
future.thenApplyAsync(this::processResponse, mainExecutor);
}
private CompletableFuture<Response> asyncGrpcCall() {
// Simula uma chamada gRPC assíncrona
CompletableFuture<Response> future = new CompletableFuture<>();
new Thread(() -> {
try {
Thread.sleep(100); // Simula o atraso da rede
future.complete(new Response(512));
} catch (InterruptedException e) {
future.completeExceptionally(e);
}
}).start();
int queueSize = ((ThreadPoolExecutor) mainExecutor).getQueue().size();
System.out.println("Current queue size: " + queueSize);
printHeapSize();
return future;
}
private Response processResponse(Response response) {
// Processa a resposta do cliente gRPC
System.out.println("Processando resposta");
return response;
}
private void printHeapSize() {
Runtime runtime = Runtime.getRuntime();
long totalMemory = runtime.totalMemory();
long freeMemory = runtime.freeMemory();
long usedMemory = totalMemory - freeMemory;
long maxMemory = runtime.maxMemory();
System.out.println("Heap size (total): " + totalMemory / (1024 * 1024) + " MB");
System.out.println("Heap size (used): " + usedMemory / (1024 * 1024) + " MB");
System.out.println("Heap size (max): " + maxMemory / (1024 * 1024) + " MB");
}
public static class Response {
private byte[] data;
public Response(int sizeInKB) {
this.data = new byte[sizeInKB * 1024]; // 1 KB = 1024 bytes
}
public byte[] getData() {
return data;
}
}
}
```
Neste exemplo, o mainExecutor é utilizado tanto para enviar requisições quanto para processar as respostas. Como o número de tarefas é muito grande (TOTAL_TASKS = 1000000), as respostas ficam acumuladas no final da fila do mainExecutor, esperando que todas as requisições sejam enviadas primeiro. Isso leva a um acúmulo de respostas pendentes, consumindo muita memória e eventualmente causando um OutOfMemoryError.
## Possíveis soluções
### 1. Use Pools de Threads Separados
Uma solução eficaz é utilizar pools de threads separados para a produção de requisições e o processamento de respostas. Isso garante que as respostas possam ser processadas independentemente do envio de novas requisições, evitando o acúmulo de tarefas na fila.
```java
package com.hugodesmarques.threads;
import java.util.concurrent.CompletableFuture;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.concurrent.ThreadPoolExecutor;
public class SeparateThreadPoolsExample {
private static final int PRODUCER_THREAD_POOL_SIZE = 10;
private static final int CONSUMER_THREAD_POOL_SIZE = 10;
private static final int TOTAL_TASKS = 1_000_000;
private final ExecutorService producerThreadPool = Executors.newFixedThreadPool(PRODUCER_THREAD_POOL_SIZE);
private final ExecutorService consumerThreadPool = Executors.newFixedThreadPool(CONSUMER_THREAD_POOL_SIZE);
public static void main(String[] args) {
SeparateThreadPoolsExample example = new SeparateThreadPoolsExample();
example.run();
}
public void run() {
for (int i = 0; i < TOTAL_TASKS; i++) {
producerThreadPool.submit(this::submitRequest);
int producerQueueSize = ((ThreadPoolExecutor) producerThreadPool).getQueue().size();
System.out.println("Producer queue size: " + producerQueueSize);
}
}
private void submitRequest() {
// Simula o envio de uma requisição para o cliente gRPC
CompletableFuture<Response> future = asyncGrpcCall();
// Processa a resposta usando o mesmo executor
future.thenApplyAsync(this::processResponse, consumerThreadPool);
}
private CompletableFuture<Response> asyncGrpcCall() {
// Simula uma chamada gRPC assíncrona
CompletableFuture<Response> future = new CompletableFuture<>();
new Thread(() -> {
try {
Thread.sleep(100); // Simula o atraso da rede
future.complete(new Response(512));
} catch (InterruptedException e) {
future.completeExceptionally(e);
}
}).start();
int consumerQueueSize = ((ThreadPoolExecutor) consumerThreadPool).getQueue().size();
System.out.println("Consumer queue size: " + consumerQueueSize);
printHeapSize();
return future;
}
private Response processResponse(Response response) {
// Processa a resposta do cliente gRPC
System.out.println("Processando resposta");
return response;
}
private void printHeapSize() {
Runtime runtime = Runtime.getRuntime();
long totalMemory = runtime.totalMemory();
long freeMemory = runtime.freeMemory();
long usedMemory = totalMemory - freeMemory;
long maxMemory = runtime.maxMemory();
System.out.println("Heap size (total): " + totalMemory / (1024 * 1024) + " MB");
System.out.println("Heap size (used): " + usedMemory / (1024 * 1024) + " MB");
System.out.println("Heap size (max): " + maxMemory / (1024 * 1024) + " MB");
}
public static class Response {
private byte[] data;
public Response(int sizeInKB) {
this.data = new byte[sizeInKB * 1024]; // 1 KB = 1024 bytes
}
public byte[] getData() {
return data;
}
}
}
```
### 2. Use um Executor Com Capacidade Limitada
Outra abordagem é limitar a capacidade do ThreadPoolExecutor para evitar que ele aceite mais tarefas do que pode processar. Isso pode ser feito usando um BlockingQueue com capacidade limitada e uma política de rejeição adequada.
```java
package com.hugodesmarques.threads;
import java.util.concurrent.ArrayBlockingQueue;
import java.util.concurrent.CompletableFuture;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.concurrent.RejectedExecutionHandler;
import java.util.concurrent.ThreadFactory;
import java.util.concurrent.ThreadPoolExecutor;
import java.util.concurrent.TimeUnit;
import java.util.concurrent.atomic.AtomicInteger;
public class ThreadPoolWithLimitsExample {
private static final int TOTAL_TASKS = 1_000_000;
private static final int THREAD_POOL_SIZE = 10;
private static final int QUEUE_CAPACITY = 100;
private final ExecutorService mainExecutor = new ThreadPoolExecutor(
THREAD_POOL_SIZE,
THREAD_POOL_SIZE,
0L,
TimeUnit.MILLISECONDS,
new ArrayBlockingQueue<>(QUEUE_CAPACITY),
new NamedThreadFactory("Producer"), // ThreadFactory com expressão lambda)
new RejectionLoggingPolicy(new ThreadPoolExecutor.CallerRunsPolicy()) // Política de rejeição com log
);
public static void main(String[] args) {
ThreadPoolWithLimitsExample example = new ThreadPoolWithLimitsExample();
example.run();
}
public void run() {
for (int i = 0; i < TOTAL_TASKS; i++) {
mainExecutor.submit(this::submitRequest);
}
}
private void submitRequest() {
// Simula o envio de uma requisição para o cliente gRPC
CompletableFuture<Response> future = asyncGrpcCall();
// Processa a resposta usando o mesmo executor
future.thenApplyAsync(this::processResponse, mainExecutor);
}
private CompletableFuture<Response> asyncGrpcCall() {
// Simula uma chamada gRPC assíncrona
CompletableFuture<Response> future = new CompletableFuture<>();
new Thread(() -> {
try {
Thread.sleep(100); // Simula o atraso da rede
future.complete(new Response(512));
} catch (InterruptedException e) {
future.completeExceptionally(e);
}
}).start();
int queueSize = ((ThreadPoolExecutor) mainExecutor).getQueue().size();
System.out.println("Current queue size: " + queueSize);
printHeapSize();
return future;
}
private Response processResponse(Response response) {
// Processa a resposta do cliente gRPC
System.out.println("Processando resposta... thread: " + Thread.currentThread().getName());
return response;
}
private void printHeapSize() {
Runtime runtime = Runtime.getRuntime();
long totalMemory = runtime.totalMemory();
long freeMemory = runtime.freeMemory();
long usedMemory = totalMemory - freeMemory;
long maxMemory = runtime.maxMemory();
System.out.println("Heap size (total): " + totalMemory / (1024 * 1024) + " MB");
System.out.println("Heap size (used): " + usedMemory / (1024 * 1024) + " MB");
System.out.println("Heap size (max): " + maxMemory / (1024 * 1024) + " MB");
}
// Política de rejeição personalizada que registra um log quando uma tarefa é rejeitada
static class RejectionLoggingPolicy implements RejectedExecutionHandler {
private final RejectedExecutionHandler handler;
public RejectionLoggingPolicy(RejectedExecutionHandler handler) {
this.handler = handler;
}
@Override
public void rejectedExecution(Runnable r, ThreadPoolExecutor executor) {
System.out.println("Tarefa rejeitada: " + r.toString() + " thread: " + Thread.currentThread().getName());
handler.rejectedExecution(r, executor);
}
}
// ThreadFactory personalizado para nomear threads
static class NamedThreadFactory implements ThreadFactory {
private final AtomicInteger threadNumber = new AtomicInteger(1);
private final String namePrefix;
public NamedThreadFactory(String namePrefix) {
this.namePrefix = namePrefix;
}
@Override
public Thread newThread(Runnable r) {
return new Thread(r, namePrefix + "-thread-" + threadNumber.getAndIncrement());
}
}
public static class Response {
private byte[] data;
public Response(int sizeInKB) {
this.data = new byte[sizeInKB * 1024]; // 1 KB = 1024 bytes
}
public byte[] getData() {
return data;
}
}
}
```
### 3. Controle o fluxo de produção com o uso de semáforos
Implementar controle de fluxo é uma abordagem eficaz para garantir que a produção de novas requisições não ultrapasse a capacidade do sistema de processar respostas. Isso pode ser feito usando semáforos (Semaphore) ou outras técnicas de controle de fluxo. A ideia é limitar o número de requisições simultâneas para evitar sobrecarregar o sistema.
```java
package com.hugodesmarques.threads;
import java.util.concurrent.CompletableFuture;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.concurrent.Semaphore;
public class ThreadPoolsWithSemaphores {
private static final int THREAD_POOL_SIZE = 10;
private static final int TOTAL_TASKS = 1_000_000;
private static final int MAX_CONCURRENT_REQUESTS = 100;
private final Semaphore semaphore = new Semaphore(MAX_CONCURRENT_REQUESTS);
private final ExecutorService mainExecutor = Executors.newFixedThreadPool(THREAD_POOL_SIZE);
public static void main(String[] args) {
ThreadPoolsWithSemaphores example = new ThreadPoolsWithSemaphores();
example.run();
}
public void run() {
for (int i = 0; i < TOTAL_TASKS; i++) {
try {
System.out.println("Submetendo request: " + i);
semaphore.acquire();
mainExecutor.submit(this::submitRequest);
} catch (InterruptedException e) {
Thread.currentThread().interrupt();
}
}
}
private void submitRequest() {
try {
// Simula o envio de uma requisição para o cliente gRPC
CompletableFuture<Response> future = asyncGrpcCall();
// Processa a resposta usando o mesmo executor
future.thenApplyAsync(this::processResponse, mainExecutor)
.whenComplete((result, ex) -> semaphore.release());
} catch (Exception e) {
semaphore.release();
}
}
private CompletableFuture<Response> asyncGrpcCall() {
// Simula uma chamada gRPC assíncrona
CompletableFuture<Response> future = new CompletableFuture<>();
new Thread(() -> {
try {
Thread.sleep(100); // Simula o atraso da rede
future.complete(new Response(512));
} catch (InterruptedException e) {
future.completeExceptionally(e);
}
}).start();
printHeapSize();
return future;
}
private Response processResponse(Response response) {
// Processa a resposta do cliente gRPC
System.out.println("Processando resposta");
return response;
}
private void printHeapSize() {
Runtime runtime = Runtime.getRuntime();
long totalMemory = runtime.totalMemory();
long freeMemory = runtime.freeMemory();
long usedMemory = totalMemory - freeMemory;
long maxMemory = runtime.maxMemory();
System.out.println("Heap size (total): " + totalMemory / (1024 * 1024) + " MB");
System.out.println("Heap size (used): " + usedMemory / (1024 * 1024) + " MB");
System.out.println("Heap size (max): " + maxMemory / (1024 * 1024) + " MB");
}
public static class Response {
private byte[] data;
public Response(int sizeInKB) {
this.data = new byte[sizeInKB * 1024]; // 1 KB = 1024 bytes
}
public byte[] getData() {
return data;
}
}
}
```
## Conclusão
O gerenciamento adequado de pools de threads em sistemas assíncronos é crucial para evitar problemas de desempenho e OutOfMemoryError (OOM). Utilizar pools de threads separados, limitar a capacidade do ThreadPoolExecutor e implementar controle de fluxo são abordagens eficazes para garantir que a produção de novas requisições não ultrapasse a capacidade do sistema de processar respostas.
Ao aplicar essas soluções, você pode garantir que seu sistema permaneça eficiente e responsivo, mesmo sob alta carga, evitando o acúmulo excessivo de tarefas na fila e prevenindo OOM.

1,921,550 | Automatically Redirect Back Upon Failed Validation | Form validation refactoring Once again back into same controller that handles logging in... | 0 | 2024-07-12T19:18:59 | https://dev.to/ghulam_mujtaba_247/automatically-redirect-back-upon-failed-validation-1b9d | webdev, beginners, programming, tutorial | ## Form validation refactoring
Once again back into same controller that handles logging in user. In this I will point your attention to all about form validation. Let in future when you want to create multiple forms in your application then you may to intensitiate the form, validation, event and duplicate part of code to give back the last submitted form and redirects it to desired page in every single controller if you work using this file.
```php
$email = $_POST['email'];
$password = $_POST['password'];
$form = new LoginForm();
if ($form->validate($email, $password)) {
if ((new Authenticator)->attempt($email, $password)) {
redirect('/');
}
$form->error('email', 'No matching account found for that email address and password.');
}
Session::flash('errors', $form->errors());
return redirect('/login');
```
According to this firstly we are creating a new form then validating it. To refactor this we have to remove first grab out parameters of first if conditional and remove the conditional. then we have to inline new form and validate statement as:
`LoginForm::validate($email, $password);`
## LoginForm class
Let's see if it can work , go to to LoginForm change the public function validate() to public static function validate () the all data inside it becomes static constructor then create a _construct method that can accept email and password in single form only $attribute, also validate method can accept an array of attributes then to move up to static construct method .
```php
protected $errors = [];
public function __construct($attributes)
{
if (!Validator::email($attributes['email'])) {
$this->errors['email'] = 'Please provide a valid email address.';
}
if (!Validator::string($attributes['password'],100 )) {
$this->errors['password'] = 'Please provide a valid password.';
}
}
public static function validate($attributes)
{
$instance = new static($attributes);
if($instance->failed()){
throw new ValidationException();
}
return $instance;
```
## Calling _construct method
So that when I call a static constructor firstly have to intensiate a class with dedicated instance, count errors If any validation fails throw new exception in LoginForm.php as 'throw new /Exception but we are using ValidationException class so:
```php
public static function validate($attributes)
{
$instance = new static($attributes);
if($instance->failed()){
throw new ValidationException();
}
return $instance;
```
## Try-catch block
When we run the it shows errors that $form is not accessible to fix this issue we have to wrap it in try and catch method as :
```php
try {
$form = LoginForm::validate($attributes = [
'email' => $_POST['email'],
'password' => $_POST['password']
]);
} catch (ValidationException $exception) {
Session::flash('errors', $form->errors());
Session::flash('old', [
'email' => $attributes['email']
]);
return redirect('/login');
}
```
Try checks either the to create a new form that accepts email and password, while catch method catches the data to check validation.
## ValidationException class
At this stage Validation Exception file is empty so the errors are not accessible and the last submitted form is not showing to user. To solve this issue using ValidationException class directory in this we have to intialize the errors and password as public read-only array as there value is one time declare by user and is not updated .
```php
namespace Core;
class ValidationException extends \Exception
{
public readonly array $errors;
public readonly array $old;
public static function throw($errors, $old){
$instance = new static;
$instance-> errors = $errors;
$instance->old=$old;
throw $instance;
;
}
}
```
Now you can check the project is working well and everything showing on output screen.
I hope that you have been clearly
Understood it.

纸飞机私信,一场简单而又充满意义的旅程
在数字化和电子通讯遍布我们生活的今天，我们或许很少能体会到曾经的简单和真挚。然而，就像一种古老而又美好的传统，纸飞机私信带来了一种独特的情感体验，让我们重新发现了文字背后的力量。
纸飞机，那轻盈的身影，可以飘荡在空中，穿越时间和空间的限制，把我们的心意送到远方。每一次折叠、每一次投掷，都是一次心灵的对话。它不需要复杂的技术或昂贵的设备，只需要一张纸，一些爱与思念，和一双愿意传达情感的手。
每一张纸飞机背后，都有一段故事。或许是朋友之间的问候，家人之间的思念，或者是爱人之间的情书。在那一刻，文字变得鲜活而真实，不再是冰冷的电子码，而是从心灵深处传递出来的真情实感。
记得小时候，在校园的角落，我们会折叠小小的纸片，写下最深情的话语，然后投向天空。我们看着它在空中飞翔，心中充满期待和希望，期待它能够到达那个特别的人手中，带给他们一丝温暖和笑容。
即使是成年后，纸飞机私信也能带来别样的感动。或许是在孤独的旅途中，或者是在思念的日子里，一张简单的纸飞机让我们感受到，即使分隔千里，心与心之间的距离并不遥远。
在这个快节奏且数字化的时代，纸飞机私信是一种珍贵的反思。它提醒我们，情感传递的方式并不在于技术的先进与否，而在于真诚和关怀。每一次折叠的动作，都是一次心灵的表达；每一次投掷的飞行，都是一次真情的传递。
因此，让我们保留这份古老而美好的传统。无论是在特殊的日子里，还是在平凡的时刻，都让纸飞机在我们之间飞翔。让文字和感情，在空中交汇，留下永恒的痕迹。
纸飞机私信，它不只是一张纸，更是一段心灵之旅的开始。

1,921,557 | Proactive Monitoring and Anomaly Detection in MySQL Server Performance | Creating a stored procedure for MySQL Server Performance anomaly detection and reporting requires a... | 0 | 2024-07-12T19:22:07 | https://dev.to/shiviyer/proactive-monitoring-and-anomaly-detection-in-mysql-server-performance-5epk | mysql, postgressql, database, opensource | Creating a stored procedure for MySQL Server Performance anomaly detection and reporting requires a comprehensive understanding of MySQL's performance metrics and system status. It involves monitoring various variables and status indicators to identify anomalies.
Here's an example of a stored procedure that inspects specific performance indicators and records a report into a table if it spots any anomalies. This scenario will examine the **`Threads_connected`**, **`Threads_running`**, and **`Innodb_row_lock_time_avg`** variables. However, you can expand this to include any other relevant variables.
Begin by creating a table to keep the anomaly reports:
`CREATE TABLE AnomalyReports (
id INT AUTO_INCREMENT PRIMARY KEY,
anomaly_time DATETIME DEFAULT CURRENT_TIMESTAMP,
description TEXT
);`
Next, create the stored procedure:
```
DELIMITER //
CREATE PROCEDURE CheckPerformanceAnomalies()
BEGIN
DECLARE threads_connected INT;
DECLARE threads_running INT;
DECLARE innodb_row_lock_time_avg INT;
DECLARE threshold_threads_connected INT DEFAULT 100; -- set your own threshold
DECLARE threshold_threads_running INT DEFAULT 20; -- set your own threshold
DECLARE threshold_innodb_row_lock_time_avg INT DEFAULT 300; -- set your own threshold (in milliseconds)
-- Get the current status
SELECT VARIABLE_VALUE INTO threads_connected
FROM performance_schema.global_status
WHERE VARIABLE_NAME = 'Threads_connected';
SELECT VARIABLE_VALUE INTO threads_running
FROM performance_schema.global_status
WHERE VARIABLE_NAME = 'Threads_running';
SELECT VARIABLE_VALUE INTO innodb_row_lock_time_avg
FROM performance_schema.global_status
WHERE VARIABLE_NAME = 'Innodb_row_lock_time_avg';
-- Check for anomalies
IF threads_connected > threshold_threads_connected THEN
INSERT INTO AnomalyReports (description)
VALUES (CONCAT('High number of connected threads: ', threads_connected));
END IF;
IF threads_running > threshold_threads_running THEN
INSERT INTO AnomalyReports (description)
VALUES (CONCAT('High number of running threads: ', threads_running));
END IF;
IF innodb_row_lock_time_avg > threshold_innodb_row_lock_time_avg THEN
INSERT INTO AnomalyReports (description)
VALUES (CONCAT('High average InnoDB row lock time: ', innodb_row_lock_time_avg, ' ms'));
END IF;
END //
DELIMITER ;
```
In this stored procedure, we extract the values of **`Threads_connected`**, **`Threads_running`**, and **`Innodb_row_lock_time_avg`** from the **`performance_schema.global_status`** table. We then compare these values to predefined thresholds. If any value exceeds its respective threshold, we insert a record into the **`AnomalyReports`** table.
You can call this procedure periodically to check for anomalies. For example:
`CALL CheckPerformanceAnomalies();`
Please note that the thresholds in this example (100 for Threads_connected, 20 for Threads_running, and 300 ms for Innodb_row_lock_time_avg) are arbitrary. They should be adjusted according to the normal operating parameters of your specific MySQL instance and workload. This procedure also assumes that the MySQL Performance Schema is enabled and configured to collect necessary metrics.

1,921,558 | How To Scrape Web Applications Using Puppeteer | Introduction Website scraping offers a pool of possibilities for extracting data from... | 0 | 2024-07-12T19:43:20 | https://dev.to/oktimmy/how-to-scrape-web-applications-using-puppeteer-pnk | ## Introduction
Website scraping offers a pool of possibilities for extracting data from websites for various purposes, such as analysis and content monitoring, web archiving and preservation, and research. Web scraping is an automated task, and Puppeteer, a popular Node.js library for headless Chrome/Chromium browser control, is a powerful tool.
Scraping multiple web pages simultaneously might be difficult, so we will also use the Puppeteer-Cluster package.
In this tutorial, we will use the popular scraping package Puppeteer to scrape the website books.toscrape.com, which was built for scraping purposes. We will use the puppeteer-cluster package to scrape the details of the first 100 books on this website.
### Prerequisite
To follow along with this tutorial, you need to have the following installed on your PC
Node >= version 16
Npm
A code editor.
You also need to have a basic knowledge of JavaScript.
#### Set up puppeteer
Install the package Puppeteer by running the command below.
```
npm install puppeteer
```
Now, create a file called index.js.
Now paste the code below into the index.js file to set up the Puppeteer and take a screenshot of the website's first page.
```
const puppeteer = require("puppeteer");
(async () => {
const browser = await puppeteer.launch({protocolTimeout:600000 });
const page = await browser.newPage();
await page.goto(`https://books.toscrape.com/index.html`, {
timeout: 60000,
});
// Set screen size
await page.setViewport({ width: 1080, height: 1024 });
await page.screenshot({ path: "homepage.png" });
await browser.close();
})();
```
Now run the command below in your terminal to see the result.
```
node index
```
When the code executes, you will see that a new image file called homepage.png has been created in the project's root folder. It contains a screenshot of the website's first landing page.
Now, let us scrape the website properly.
### How To Grab Selectors From a Website
To scrape the website, you must grab selectors pointing to each element you want to scrape data.
To do this,
- Open your browser
- Navigate to the webpage from which you want to scrape data; we will visit the Book To Scrape Website for this tutorial.
- Right-click on the time you wish to scrape, and click on inspect, as shown below.
- This opens the developers' tools to display the web page's HTML source document and highlights the inspected element.
- Right-click on the element from which you wish to scrape data in the dev tools. This opens another modal.
- Highlight the Copy option, and a submenu pops up beside the initial modal. Select the Copy Selector.
- This copies the exact path to the element. However, you can edit the path based on your understanding of the page’s HTML document.
### Scrape The First Book On the Page
Grab the selector for the first book div to scrape the first book. Then, grab the element's content using the _$eval_ method. This method expects two properties: the element path selector and a callback function where you define the property you need.
Below is a demo of implementing the _$eval_ method.
```
const firstBook = await page.$eval(
"#default > div > div > div > div > section > div:nth-child(2) > ol > li:nth-child(1) > article",
(e) => e.innerHTML
);
console.log(firstBook);
```
When you add this function to the demo, we wrote earlier before the `browser.close` function. When you run the scraper in the terminal, you should have the HTML within the article element displayed in the console.
### Scrape Multiple Books
Using the _$$eval_ method, it is possible to scrape multiple elements, such as li and ol. The _$$eval_ method expects two properties: the selector of the parent element containing the listed items and a callback function that maps over the array of elements and grabs the specified data from a selected element. This method returns an array of the specified data, which it grabs from each element in the parent element whose selector was specified.
Below is a demo of how to do that with the books on the first page of the Books to Scrape website.
```
const booksArray = await page.$$eval(
"#default > div > div > div > div > section > div:nth-child(2) > ol> li",
(elements) =>
elements.map((el, i) => {
const bookTitle = el.querySelector("h3> a").getAttribute("title");
});
);
```
### Scrape Data From The First 100 Books on the website
In this section, we will scrape the first 100 books on this website. This website has 50 pages, and each page contains 20 books. This means we will be scraping through the first 5 pages of the website.
To do this, paste the code below in the scraper's main function.
```
const puppeteer = require("puppeteer");
(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
let flattenedArray;
const bookDataArray = [];
for (let index = 1; index <= 5; index++) {
if (index === 1) {
// Navigate the page to a URL
await page.goto(`https://books.toscrape.com/index.html`, {
timeout: 60000,
});
//Take screenshot of each page
await page.screenshot({ path: `images/page-${index}.png` });
} else {
// Navigate the page to a URL
await page.goto(
`https://books.toscrape.com/catalogue/page-${index}.html`,
{
timeout: 60000,
}
);
await page.screenshot({ path: `images/page-${index}.png` });
}
const booksArray = await page.$$eval(
"#default > div > div > div > div > section > div:nth-child(2) > ol> li",
(elements) =>
elements.map((el, i) => {
const bookTitle = el.querySelector("h3> a").getAttribute("title");
const bookPrice = el.querySelector("p.price_color").innerText;
const imageLink = el.querySelector("img").getAttribute("src");
const inStock = el.querySelector("p.availability").innerText;
const bookDetailsLink = el
.querySelector("h3> a")
.getAttribute("href");
const data = {
i,
title: `${bookTitle}`,
detailsLink: `${bookDetailsLink}`,
price: `${bookPrice}`,
image: `https://books.toscrape.com/${imageLink}`,
availability: `${inStock}`
};
return data;
})
);
//Add an index number to each book detail.
const updatedBookNoInDataArray = booksArray.map((e) => {
return {
...e,
i: index == 1 ? e.i + 1 : (index - 1) * 20 + e.i + 1,
};
});
bookDataArray.push(updatedBookNoInDataArray);
//Flatten out the array here
flattenedArray = [].concat(...bookDataArray);
}
await browser.close();
})();
```
In the above code snippet, we first declared a _flattenedArray_ and a _bookDataArray_ to store the array of data we scraped. The _bookdataArray_ will contain an array of arrays, and then we flatten out the result into the _flattenedArray_ variable.
We then loop over the first 5 pages by dynamically changing the page number variable on the URL as we loop through each page. We check if we are on the first page, declare the URL for the first page, and then dynamically increment each number as the loop executes.
Then, on each page, we use the _$$eval_ function to grab the array of books. For each book item, we get the following data: the title, the price, the link to the cover image, the link to the description page, and the availability of the book.
So, each page returns an array of 20 items. This means, at the end of each loop, the _booksArray_ contains 20 items. Then we map over the _booksArray_ to add a sequential index to the items based on the page where they were scraped from.
Then, each booksArray is pushed into the _bookDataArray_. The _booksDataArray_ contains five arrays, each containing 20 book items. Then, we flatten out this array to give just one array, the _flattenedArray_.
If you log the _flattenedArray_ to the console and run the script, you should have a single array of 100 items logged to the console. Each item would be an object with the following keys: i, _title_, _detailsLink_, _price_, _image_, and _availability_. You would also notice the index of each object starts at 1 and ends at 100.
## Scrape The Book Description Data For Each of The 100 Books
In this section, we will scrape the book description data for each of the 100 books using the details link. To do this, we will be using another puppeteer package called `puppeteer-cluster`.
To get started, install the package by running the command below in your terminal.
```
npm install puppeteer-cluster
```
Next, import the package into your index file.
```
const { Cluster } = require("puppeteer-cluster");
```
Now at the bottom of the script before the _browser.close_ method, declare a new array that will store the data we will be scraping from each book details page.
```
//some code
const addedData = [];
```
Initialize the cluster instance by pasting the code below in the script.
```
const cluster = await Cluster.launch({
concurrency: Cluster.CONCURRENCY_PAGE,
maxConcurrency: 100,
timeout: 10000000,
});
```
The code snippet above shows how we set the concurrency to **CONCURRENCY_PAGE**. This means that each worker in the cluster will have its own separate Puppeteer instance with a single page. This allows parallel task execution on different web pages.
The _maxConcurrency_ is set to 100. This means that we will have a maximum of 100 workers running simultaneously. We set it to 100 because we intend to work with just 100 different pages.
The timeout option sets the timeout duration for tasks the cluster workers execute. This timeout defines the maximum amount of time a worker has to complete a task before it's considered timed out and potentially restarted. The value is specified in milliseconds (ms). Here, it is set to 10,000,000 ms, which is very high, about 10,000 seconds.
Next, declare a callback function that acts as an event listener. This function handles errors that may occur when the cluster is executing each of our pages and logs the error message to the console.
```
//Catch any error that occurs when you scrape a particular page and log it to the console.
cluster.on("taskerror", (err, data) => {
console.log(`Error Crawling ${data}: ${err.message}`);
});
```
Next, write the function you need the scraper to execute on each page by pasting the code below into the main scraper script.
```
//Describe what you want the scraper to do on each page here
await cluster.task(async ({ page, data: url }) => {
await page.goto(url, { timeout: 100000 });
const details = await page.$eval("#content_inner > article > p", (el) => {
if (el === undefined) {
return "";
} else {
return el.innerText;
}
});
const tax = await page.$eval(
"#content_inner > article > table > tbody > tr:nth-child(5) > td",
(el) => {
if (el === undefined) {
return "";
} else {
return el.innerText;
}
}
);
const noOfleftInStock = await page.$eval(
"#content_inner > article > table > tbody > tr:nth-child(6) > td",
(el) => {
if (el === undefined) {
return "";
} else {
return el.innerText;
}
}
);
addedData.push({ details, noOfleftInStock, tax });
});
```
We check if the page contains the element we are targeting. If it does not, we return an empty string. We then return an object containing the book's details, the number left in stock, and the tax.
```
for (const url of flattenedArray) {
if (url.detailsLink.startsWith("catalogue/")) {
await cluster.queue(`https://books.toscrape.com/${url.detailsLink}`);
} else {
await cluster.queue(
`https://books.toscrape.com/catalogue/${url.detailsLink}`
);
}
}
```
Then, we describe a for loop for each of the book items in the flattened array. Then, we check if the details link begins with “catalogue/” and just queue the URL by concatenating it with the root URL. If it does not, we add it to the root URL before concatenating. This is because the _catalogue_ path is required in the URL path to retrieve the book details page.
Next, add the lines below to the code.
```
await cluster.idle();
await cluster.close();
```
The _**idle**_ method instructs the cluster to wait for all currently running tasks within its workers of the cluster instance to finish. This ensures that all scraping activities initiated by the _**queue**_ method are completed before proceeding.
The close method terminates the cluster entirely. This process involves gracefully shutting down all browser instances associated with the cluster workers and releasing any resources allocated to the cluster.
Then, we add the retrieved data from each page to our flattened array using the code snippet below.
```
const finalbookDataArray = flattenedArray.map((e, i) => {
return {
...e,
bookDescription: addedData[i].details,
tax: addedData[i].tax,
noOfleftInStock: addedData[i].noOfleftInStock,
};
});
```
Finally, let us write all the scraped data into a json file. We can use the node’s fs package as shown below.
```
//Import the package at the top of the file
const fs = require("fs");
const bookDataArrayJson = JSON.stringify(finalbookDataArray, null, 2);
fs.writeFileSync("scraped-data.json", bookDataArrayJson);
```
The final code should look like this.
```
const puppeteer = require("puppeteer");
const { Cluster } = require("puppeteer-cluster");
const fs = require("fs");
(async () => {
const browser = await puppeteer.launch({ protocolTimeout: 600000 });
const page = await browser.newPage();
let flattenedArray;
const bookDataArray = [];
for (let index = 1; index <= 5; index++) {
if (index === 1) {
// Navigate the page to a URL
await page.goto(`https://books.toscrape.com/index.html`, {
timeout: 60000,
});
await page.screenshot({ path: `images/page-${index}.png` });
} else {
// Navigate the page to a URL
await page.goto(
`https://books.toscrape.com/catalogue/page-${index}.html`,
{
timeout: 60000,
}
);
await page.screenshot({ path: `images/page-${index}.png` });
}
const booksArray = await page.$$eval(
"#default > div > div > div > div > section > div:nth-child(2) > ol> li",
(elements) =>
elements.map((el, i) => {
const bookTitle = el.querySelector("h3> a").getAttribute("title");
const bookPrice = el.querySelector("p.price_color").innerText;
const imageLink = el.querySelector("img").getAttribute("src");
const inStock = el.querySelector("p.availability").innerText;
const bookDetailsLink = el
.querySelector("h3> a")
.getAttribute("href");
const data = {
i,
title: `${bookTitle}`,
detailsLink: `${bookDetailsLink}`,
price: `${bookPrice}`,
image: `https://books.toscrape.com/${imageLink}`,
availability: `${inStock}`,
};
return data;
})
);
//Add an index number to each book detail.
const updatedBookNoInDataArray = booksArray.map((e) => {
return {
...e,
i: index == 1 ? e.i + 1 : (index - 1) * 20 + e.i + 1,
};
});
bookDataArray.push(updatedBookNoInDataArray);
//Flatten out the array here
flattenedArray = [].concat(...bookDataArray);
}
const addedData = [];
const cluster = await Cluster.launch({
concurrency: Cluster.CONCURRENCY_PAGE,
maxConcurrency: 100,
timeout: 10000000,
});
//Catch any error that occurs when you scrape a particular page and log it to the console.
cluster.on("taskerror", (err, data) => {
console.log(`Error Crawling ${data}: ${err.message}`);
});
//Describe what you want the scraper to do on each page here
await cluster.task(async ({ page, data: url }) => {
await page.goto(url, { timeout: 100000 });
const details = await page.$eval("#content_inner > article > p", (el) => {
if (el === undefined) {
return "";
} else {
return el.innerText;
}
});
const tax = await page.$eval(
"#content_inner > article > table > tbody > tr:nth-child(5) > td",
(el) => {
if (el === undefined) {
return "";
} else {
return el.innerText;
}
}
);
const noOfleftInStock = await page.$eval(
"#content_inner > article > table > tbody > tr:nth-child(6) > td",
(el) => {
if (el === undefined) {
return "";
} else {
return el.innerText;
}
}
);
// console.log({details, noOfleftInStock, tax})
addedData.push({ details, noOfleftInStock, tax });
});
for (const url of flattenedArray) {
if (url.detailsLink.startsWith("catalogue/")) {
await cluster.queue(`https://books.toscrape.com/${url.detailsLink}`);
} else {
await cluster.queue(
`https://books.toscrape.com/catalogue/${url.detailsLink}`
);
}
}
await cluster.idle();
await cluster.close();
const finalbookDataArray = flattenedArray.map((e, i) => {
return {
...e,
bookDescription: addedData[i].details,
tax: addedData[i].tax,
noOfleftInStock: addedData[i].noOfleftInStock,
};
});
const bookDataArrayJson = JSON.stringify(finalbookDataArray, null, 2);
fs.writeFileSync("scraped-data.json", bookDataArrayJson);
await browser.close();
})();
```
Now create a folder named **Images** and execute the scraper by running the command below in the terminal
```
node index
```
When the scraper finishes executing, you should have 5 images in your images folder and a file named **_scraped-data.json_**, which contains the json data of data from the website.
## Wrapping Up
So far, in this tutorial, we have learned how to scrape data from a website using Puppeteer and how to scrape multiple pages at once using the Puppeteer-cluster package. You can get the full code on my repo [here](https://github.com/ok-timmy/Puppeeteer-Tutorial)
You can improve your skills by scraping websites like e-commerce and real estate websites. You can also use the puppeteer cluster to create a scraper comparing data between two or more websites.
To learn more about Puppeteer, you can check out their documentation here. You can also check out the puppeteer-cluster package here.
In my next Puppeteer series, I will discuss how to use Puppeteer for Integration testing in web applications.

The Clerk team has been hard at work shipping new features to help you build secure applications faster. Here’s a rundown of the highlights:
## Clerk Elements (Beta)
[](https://go.clerk.com/X87UqBt)
Clerk Elements is currently in beta and introduces an entirely new set of unstyled UI primitives that make it easy to build completely custom authentication and user management UIs on top of Clerk's APIs and business logic.
- **Customize with CSS Frameworks**: Because everything is unstyled by default, Clerk Elements gives you complete control over the markup rendered in your authentication flows. Rendered markup accepts a `className` prop for easy styling with CSS frameworks such as Tailwind.
- **Extend with Component Libraries**: Clerk Elements also support the `asChild` prop, popularized by component libraries like [Radix](https://www.radix-ui.com/primitives/docs/guides/composition). Bring your existing component library and it'll take care of the rest.
To learn more, visit the [Clerk Changelog](https://go.clerk.com/X87UqBt) and [Clerk Elements docs →](https://go.clerk.com/a3KoX3J)
## Google One Tap
[](https://go.clerk.com/PtfFHr1)
Google One Tap support introduces seamless, one-click user sign-ins and sign-ups. This allows your users to effortlessly access your services without having to remember passwords or undergo lengthy registration processes.
- **New `<GoogleOneTap />` Component**: If you have already configured Google OAuth with custom credentials, adding support for Google One Tap is as easy as including the new `<GoogleOneTap />` component.
- **Support for Custom Flows & Non-React Environments**: For those building applications that require custom flows or do not use React, Google One Tap is supported via [clerk-js](https://clerk.com/docs/references/javascript/overview#clerk-js).
To learn more, visit the [Clerk Changelog](https://go.clerk.com/PtfFHr1) and [`<GoogleOneTap />` component docs →](https://go.clerk.com/098Ao1L)

1,921,561 | SSH with gpg-agent on systemd | There's a lot of information floating around on the web explaining how to replace ssh-agent with... | 0 | 2024-07-12T19:43:05 | https://dev.to/ehuelsmann/ssh-with-gpg-agent-on-systemd-5ddf | ssh, gpg, systemd, yubikey | There's a lot of information floating around on the web explaining how to replace `ssh-agent` with `gpg-agent`. This is important if you - like me - want to use a [yubikey](https://www.yubico.com/) or smart card device to store the private key of your SSH key pair.
Unfortunately, none of the advice worked for me with the following system setup:
- systemd v249
- GNOME desktop 42.9
- Ubuntu 22.04
Although the above is quite specific, I expect the information below to much more generally applicable.
## Prerequisite for Yubikeys and smart cards
GPG needs `pcscd` and `scdaemon` to be able to access private keys stored on a yubikey or smart card:
```bash
$ sudo apt install pcscd scdaemon
$ systemctl enable --now pcscd
$ systemctl enable --now scdaemon
```
After running these commands, `gpg --card-status` should provide you with information about your smart card.
## Configuring GPG with ssh-agent support
To enable ssh-agent support in gpg-agent, add the following to your gpg-agent.conf:
```plain
# ~/.gnupg/gpg-agent.conf
enable-ssh-support
```
## Enabling `gpg-agent` (per user)
`gpg-agent` is a per-user service, which systemd facilitates with the `--user` flag on the `systemctl` command:
```bash
$ systemctl enable --user --now gpg-agent.socket
$ systemctl enable --user --now gpg-agent-ssh.socket
```
If you forget to add the `.socket` extension, systemctl will throw an error about a missing `[Install]` section in the service definition. Please note that the sockets are to be enabled; the service itself is to be left untouched.
Verifying status of the GPG agent can be done using:
```bash
$ systemctl status --user gpg-agent.socket
$ systemctl status --user gpg-agent-ssh.socket
```
Although the service is now running, the environment shows an incorrect value for `SSH_AUTH_SOCK` (`/run/user/<uid>/keyring/ssh`).
## Fixing SSH_AUTH_SOCK
There are several configurations blocking successful use of `gpg-agent` for SSH, causing the value of `SSH_AUTH_SOCK` to be incorrect.
### Disable `ssh-agent` user service
If it is enabled, this service needs to be disabled, as it is conflicting:
```bash
$ systemctl disable --user --now ssh-agent
```
### Disable Xsession.options ssh-agent
The `Xsession` script tries to start an `ssh-agent`. This can be disabled by modifying `/etc/X11/Xsession.options` and `/etc/X11/Xsession.options.d/*.conf`, making sure the last file loaded contains:
```plain
no-use-ssh-agent
```
This is best achieved by creating a file named `/etc/X11/Xsession.options.d/zz-no-ssh-agent.conf` with that content.
### Disable GNOME Keyring (gnome-keyring-ssh.desktop)
GNOME Keyring tries to start an SSH agent if none is running. The way to disable this is by executing the following commands - which are different from those published all around:
```plain
$ cp /etc/xdg/autostart/gnome-keyring-ssh.desktop ~/.config/autostart/gnome-keyring-ssh.desktop
$ echo "X-GNOME-Autostart-enabled=false" >> ~/.config/autostart/gnome-keyring-ssh.desktop
$ echo "Hidden=true" >> ~/.config/autostart/gnome-keyring-ssh.desktop
```
The "Hidden=true" addition is advertized all around the web, but didn't work for me.
### Setting SSH_AUTH_SOCK
Using systemd to manage `gpg-agent` has one drawback: systemd doesn't set environment variables in the user shell session. This can be solved by adding this snippet to the user's `bashrc`:
```bash
# to be appended to ~/.bashrc
if [[ -z "$SSH_AUTH_SOCK" ]]
then
if [[ -e "/run/user/$(id -u)/gnupg/S.gpg-agent.ssh" ]]
then
export SSH_AUTH_SOCK="/run/user/$(id -u)/gnupg/S.gpg-agent.ssh"
fi
fi
```
## Conclusion
Yubikey and smart card support with private keys on the key or card does not come out of the box, even in this day and age, but with a bit of configuration, setting up private keys on a smart card and making it work under GNOME, is doable.

1,921,564 | Don't Rebuild Yourself - an Intro to Nix Package Caches | In previous blog posts, we’ve talked about how we speed up Devbox installs by fetching package... | 0 | 2024-07-12T19:36:54 | https://www.jetify.com/blog/dont-rebuild-yourself-an-intro-to-nix-package-caches/ | nix, learning, devops | In previous blog posts, we’ve talked about how we speed up Devbox installs by [fetching package closures directly](https://www.jetify.com/blog/how-we-sped-up-nix-package-installs-in-devbox/) from the official Nix Cache. This blog post will dig a bit more into how a Nix cache solution works, and how it can speed up your package installation time. In addition to covering the official Nix cache, we’ll talk about how you can integrate the [Jetify Cache](https://www.jetify.com/cache) with Devbox to speed up your shells and share your custom packages across your team.
## Building Reproducible Packages with Nixpkgs
The [Nixpkgs repository](https://www.github.com/NixOS/nixpkgs) provides over 100,000 packages, and supports multiple architectures and operating systems. Nix packages define all their requirements and dependencies within their build definition, making them reproducible and isolating them from the dependencies on your host machine. This means you can install multiple versions of the same Nix package on the same machine without conflicts.
This isolation comes with a trade-off. Due to the unique way Nix defines packages, it can't simply download upstream binaries. Instead, it needs to ensure the package links its dependencies in the Nix store correctly. The only way to guarantee a package does this is to build the package and it’s dependencies from source, and link it’s dependencies within the Nix store.
All that building can add up. Building a package like MongoDB can take up to 30 minutes, and that's just for MongoDB. Building a full closure from source can take hours, and updating a dependency in the graph means you have to rebuild the whole universe. All that building leads to the [obligatory XKCD comic](https://xkcd.com/303/):
## Speeding up Installations with Nix Package Caches
Fortunately, Nix's reproducibility and isolation also makes it easy to share and reuse the build outputs of packages. Each Nix package has a [unique store path](https://www.jetify.com/blog/how-we-sped-up-nix-package-installs-in-devbox/) determined by the hash of its inputs. This unique store path means Nix can identify and reuse build outputs easily.
This reuse happens in two layers:
1. Nix can reuse existing packages and outputs in your **Nix Store**. When Nix starts building your package's dependencies, it first checks if a package with the correct store path exists in your local store, and then reuses that store path. The Nix Store enables sharing packages on a single machine, but you'll need a different layer if you want to share across machines.
2. To share across machines, you need a Nix Cache. If someone is building and pushing the packages you need to a cache, you can skip building and download precisely what you need. Developers can configure multiple Nix caches as "substituters," which tell the Nix Daemon where to look for “substitute” store paths that aren't in their current Nix store.
The largest cache is the [Public Cache](https://cache.nixos.org/) maintained by the NixOS Foundation. The Foundation knows that users want to avoid constantly rebuilding, so they build most of Nixpkgs packages in [Hydra](https://github.com/NixOS/hydra) (Nix’s CI build system) and push them to the public cache. For the most popular binaries and platforms, the Nix Public Cache has you covered.
The public cache does have some gaps, however, that your project can fall into
1. Packages outside the Nixpkgs like custom packages on our machine or flakes hosted in public repositories.
2. Packages such as MongoDB, Terraform, and Vault aren't hosted in the Nix cache because they lack an open-source license.
3. Older packages, or packages on less popular platforms, can be garbage collected or excluded from the public cache.
For this reason, many developers set up their own Nix caches to use as substituters for their custom packages. Technically, any machine running Nix can serve as a cache or substituter for another machine. If you're trying to support a team, however, managing issues like trust, access control, and populating the cache with the latest packages can take a lot of extra effort and development.
## Jetify Cache: A Package Cache designed for Devbox and Nix
For teams that want a cache without the extra overhead, we built the [Jetify Cache](https://www.jetify.com/cache). Jetify Cache is an enterprise grade Nix Cache that integrates nicely with Devbox, so you can speed up your shells with little extra effort.
Our Jetify Cache offers two solutions that can help your team develop faster:
1. For packages in Nixpkgs that are not available in the Nix Cache, we offer the [**Jetify Prebuilt Cache**](https://www.jetify.com/devbox/docs/cloud/cache/prebuilt_cache). This provides prebuilt versions of packages not in the official Nix Cache. If you have a Jetify Cloud account, Devbox will automatically configure the Prebuilt cache as a substituter. When Devbox prepares to install a package, it will use the Prebuilt cache if there are any gaps in your local Nix Store or the official Nix cache.
2. For your custom packages and flakes, we offer the [**Jetify Private Cache**](https://www.jetify.com/devbox/docs/cloud/cache). Jetify Private Cache lets you share binaries across all your devices and developers. After you build your Devbox project (either locally, or in CI), you can run `devbox cache upload` to push the entire closure of your project to the cache. Developers who share your Jetify Cloud Project can then easily download their packages from the cache without building from source.
## Devbox: Optimized for Nix Package Caching
Devbox can automatically configure the Jetify Cache caches for you when you authenticate with Jetify Cloud With the Jetify Cache enabled, you now have 4 layers where Devbox and Nix can check for binaries before building from source:
1. The Nix Store (`/nix/store`)
2. Your Jetify Private Cache
3. The Official Nix Cache (cache.nixos.org)
4. The Jetify Prebuilt Cache.
As mentioned above, Devbox can install packages by copying them directly from the cache, without needing to re-run evaluation steps. We do this by retrieving the store paths directly from [Nixhub](https://www.nixhub.com/) (our Nix Package Search engine) at install time, and then save the store paths in our `devbox.lock` file. With this optimized cache experience, you can start reducing your installation times in seconds.
## Keep Up To Date on Jetify and Devbox
If you want to speed up your package installs, the Jetify Prebuilt Cache is available to any developer who signs up for a free [Jetify Cloud](https://cloud.jetify.com/) account. If you have custom packages or binaries you want to cache, you can check out our [pricing plans](https://www.jetify.com/pricing) for Jetify Cloud.
We’d love to hear your feedback on Devbox and Jetify Cache. You can follow us on [Twitter](https://twitter.com/jetify_com), or chat with our developers live on our [Discord Server](https://discord.gg/jetify). We also welcome issues and pull requests on our [Github Repo](https://github.com/jetify-com/devbox). | lagoja |

自动群发在YouTube平台上是一个备受争议的话题。随着社交媒体和视频内容的普及，许多人都希望通过YouTube获得更多的关注和观众。然而，一些人选择采用自动群发工具，试图通过大量的评论、订阅和点赞来提升他们的视频的曝光度和影响力。
自动群发工具通常是由第三方开发，它们承诺可以自动化地进行评论、点赞和订阅，从而快速增加视频的观看次数和互动数。然而，这些工具的使用往往违反了YouTube的使用政策，特别是关于虚假活动和人工操纵内容的条款。YouTube严格禁止使用任何形式的自动化工具来增加视频的观看次数或互动，这些违规行为一经发现可能会导致视频被删除或者频道被封禁。
自动群发不仅违反了YouTube的政策，还可能损害真正内容创作者的利益。通过人为生成的评论和点赞，观众很容易识别出视频的真实度和内容的质量。这种人为干预不仅让观众失去信任感，还会影响整个社区的氛围和互动质量。
另外，自动群发也存在一定的风险，因为这些工具通常需要访问用户账户，并可能导致账户被盗或个人信息泄露的风险。对于希望在YouTube上建立长期影响力的内容创作者来说，使用这些工具是不可取的选择，因为它们可能会导致不可逆的影响。
作为YouTube社区的一部分，每个人都有责任遵守平台的使用规范和道德准则，以确保公平和透明的内容竞争环境。只有通过真实的努力和优质的内容，才能获得真正的观众认可和持久的影响力。因此，远离自动群发工具，关注内容质量和真实互动，才能在YouTube上取得长远的成功。

1,921,571 | Effective Strategies for Troubleshooting MongoDB Wait Events in Long-Running Query Operations | Troubleshooting MongoDB Wait Events in Long-Running Query Operations When working with... | 0 | 2024-07-12T19:49:03 | https://dev.to/shiviyer/effective-strategies-for-troubleshooting-mongodb-wait-events-in-long-running-query-operations-2j3e | mongodb, nosql, database, opensource | ### Troubleshooting MongoDB Wait Events in Long-Running Query Operations
When working with MongoDB, long-running queries can significantly impact the performance and responsiveness of your database. Troubleshooting wait events associated with these queries is crucial for identifying bottlenecks and optimizing performance. This guide provides an in-depth look at common wait events in MongoDB and how to address them effectively.
#### Understanding Wait Events
Wait events in MongoDB occur when operations are waiting for a resource to become available. These events can be due to various reasons such as locks, CPU contention, or I/O operations. The following are some common wait events you may encounter:
1. **Lock Waits**: Occur when a query is waiting for a lock on a document or collection.
2. **CPU Waits**: Occur when there is CPU contention and the query is waiting for CPU resources.
3. **I/O Waits**: Occur when the query is waiting for disk I/O operations to complete.
4. **Network Waits**: Occur when there is network latency affecting the query execution.
#### Identifying Wait Events
To identify wait events in MongoDB, you can use various tools and commands:
**Profiler**: MongoDB's built-in profiler can help identify slow queries and their associated wait events.
```bash
db.setProfilingLevel(2)
db.system.profile.find({ millis: { $gt: 100 } }).sort({ ts: -1 }).limit(5)
```
**mongotop**: Provides real-time reporting of read and write activity on a MongoDB instance.
```bash
mongotop
```
**mongostat**: Shows a summary of database operations and can help identify CPU and I/O waits.
```bash
mongostat
```
**$currentOp**: Provides details about currently running operations, including lock information.
```bash
db.currentOp({ "active": true, "secs_running": { $gt: 10 } })
```
#### Troubleshooting Strategies
Once you have identified the wait events, the following strategies can help mitigate their impact:
**Optimize Queries**:
- **Indexing**: Ensure that your queries are using indexes efficiently. Use the explain() method to analyze query execution plans.
```bash
db.collection.find({ field: value }).explain("executionStats")
```
- **Query Rewrite**: Rewrite queries to be more efficient. Avoid full collection scans by using selective criteria.
**Adjust Lock Settings**:
- **Lock Granularity**: Use appropriate lock granularity settings. MongoDB 3.0+ supports collection-level locking, which can reduce contention.
- **Read/Write Concerns**: Adjust read and write concerns to balance consistency and performance.
**Optimize Hardware Resources**:
- **CPU**: Ensure adequate CPU resources are available. Consider upgrading hardware or optimizing workloads.
- **Memory**: Increase available memory to reduce I/O waits by ensuring frequently accessed data is in memory.
- **Disk I/O**: Use faster storage solutions (e.g., SSDs) and ensure proper disk configuration to handle I/O demands.
**Monitor and Tune**:
- **Monitoring Tools**: Use monitoring tools like MongoDB Cloud Manager or third-party solutions to track performance metrics and identify bottlenecks.
- **Performance Tuning**: Regularly review and tune performance settings based on workload characteristics.
**Network Optimization**:
- **Network Latency**: Reduce network latency by optimizing network configurations and using geographically distributed deployments.
- **Replica Sets**: Configure replica sets to ensure high availability and distribute read operations across replicas.
#### Example: Addressing a Long-Running Query
Consider a scenario where a query on the `orders` collection is taking too long due to I/O waits:
**Identify the Query**:
```bash
db.system.profile.find({ millis: { $gt: 1000 } }).sort({ ts: -1 }).limit(1)
```
**Analyze the Query Execution Plan**:
```bash
db.orders.find({ status: "shipped" }).explain("executionStats")
```
**Add an Index**:
```bash
db.orders.createIndex({ status: 1 })
```
**Re-run the Query and Monitor**:
```bash
db.orders.find({ status: "shipped" }).explain("executionStats")
```
**Optimize Hardware if Needed**:
- **Upgrade to SSDs**: If I/O waits persist, consider upgrading to SSDs for faster disk access.
By following these steps, you can effectively troubleshoot and optimize long-running query operations in MongoDB, ensuring better performance and resource utilization.

1,921,575 | Bitmasking em Go: Uma Técnica Poderosa para Gerenciamento de Opções | Introdução Bitmasking é uma técnica eficiente e poderosa utilizada na programação para... | 0 | 2024-07-13T02:59:36 | https://dev.to/leonancarvalho/bitmasking-em-go-uma-tecnica-poderosa-para-gerenciamento-de-opcoes-2idb | go, programming, performance, architecture |
### Introdução
Bitmasking é uma técnica eficiente e poderosa utilizada na programação para representar e manipular conjuntos de opções usando operações bitwise. Esta técnica permite armazenar múltiplos estados booleanos em um único valor numérico, onde cada bit representa uma opção distinta. Embora eu tenha começado minha jornada de programação com PHP, onde bitmasking é bastante utilizado, descobri que essa técnica é igualmente poderosa em outras linguagens como C, Java e até mesmo nas linguagens mais modernas como Go.
Neste artigo, vou compartilhar como implementar bitmasking em Go e discutir alguns exemplos práticos baseados na minha experiência.
### Conceitos Básicos
#### O que é Bitmasking?
Bitmasking envolve o uso de operações bitwise para gerenciar conjuntos de flags ou opções. Cada opção é representada por um bit em um valor inteiro, permitindo que múltiplas opções sejam combinadas e verificadas de maneira eficiente através da compactação de dados, permitindo economizar espaço de memória e melhorar o desmpenho de programas críticos.
#### Operadores Bitwise
Os operadores bitwise mais comuns utilizados em bitmasking são:
- **AND (`&`)**: Usado para verificar se um bit específico está definido.
- **OR (`|`)**: Usado para definir bits específicos.
- **XOR (`^`)**: Usado para alternar bits específicos.
- **NOT (`~`)**: Usado para inverter todos os bits.
#### Implementação em Go
Vamos criar uma implementação de bitmasking em Go, utilizando um exemplo de sistema de configuração para uma estrutura chamada `Service`.
Usaremos o tipo `iota` para definir constantes de opções, onde cada constante representa uma opção específica como um bit único.
```go
package main
import (
"fmt"
)
type ServiceOption int
const (
WITH_OPTION_A ServiceOption = 1 << iota
WITH_OPTION_B
WITH_OPTION_C
)
```
Mas atenção, com o tipo `int`podemos definir somente no máximo 32 opções de flag. Por isso, Ao definir uma flag esteja atento à possibilidade de crescimento desse conjunto.
Se você precisa superar a limitação de 32 flags que um tipo `int` permite, você pode considerar algumas alternativas que suportam mais bits. Aqui estão algumas opções:
##### Inteiros de 64 Bits
Em Go, você pode usar o tipo int64 para representar até 64 flags.
```go
type ServiceOption int64
```
##### Usar um Array de Inteiros
Se você precisar de um número ainda maior de flags, pode usar um array ou slice de inteiros. Cada elemento do array pode armazenar 32 ou 64 flags, dependendo do tipo de inteiro usado (int32 ou int64).
```go
type ServiceOption int64
type ServiceOptions [2]int64 // 2 * 64 = 128 flags
const (
WITH_OPTION_A ServiceOption = 1 << iota
WITH_OPTION_B
WITH_OPTION_C
// Continue até 127 (2 * 64 - 1)
)
func (p *ServiceOptions) Set(flag ServiceOption) {
index := flag / 64
bit := flag % 64
p[index] |= 1 << bit
}
func (p *ServiceOptions) Clear(flag ServiceOption) {
index := flag / 64
bit := flag % 64
p[index] &^= 1 << bit
}
func (p *ServiceOptions) Has(flag ServiceOption) bool {
index := flag / 64
bit := flag % 64
return p[index]&(1<<bit) != 0
}
```
Você também pode criar um tipo personalizado que usa slices ou arrays internamente para armazenar bits, mas torna tudo um pouco mais complexo, então adicionei um exemplo implementação no [Go Playground](https://go.dev/play/p/-nCdZ3tLzPU)
##### Atribuindo as flags na estrutura de dados
Ao Definirmos nossa bitmask agora vamos anexá-lo à uma estrutura chamada `Service` que incluirá um campo `flags` para armazenar as opções combinadas, vamos usar o operador Bitwise` | OR` para para definir bits específicos na criação do objeto.
```go
type Service struct {
flags ServiceOption
}
func NewService(flags ...ServiceOption) *Service {
var opts ServiceOption
for _, flag := range flags {
opts |= flag
}
return &Service{
flags: opts,
}
}
```
##### Verificando se uma flag existe no bitmask
Com o construtor completo agora só precisamos criar uma forma de verificar se uma determinada opção está definida , vamos implementar o método HasOption com o operador bitwise `&`AND para retornar a existência da flag dentro da nossa bitmask de flags.
```go
func (s *Service) HasOption(flag ServiceOption) bool {
return s.flags&flag != 0
}
func main() {
defaultService := NewService()
fmt.Println("Default Service")
fmt.Println("Has Option A:", defaultService.HasOption(WITH_OPTION_A))
fmt.Println("Has Option B:", defaultService.HasOption(WITH_OPTION_B))
modifiedService := NewService(WITH_OPTION_A | WITH_OPTION_B)
fmt.Println("\nModified Service")
fmt.Println("Has Option A:", modifiedService.HasOption(WITH_OPTION_A))
fmt.Println("Has Option B:", modifiedService.HasOption(WITH_OPTION_B))
}
```
Agora nosso exemplo está completo, https://go.dev/play/p/rcHwLs-rUaA
_Exemplo de uso do Iota para definir constantes Enums que representam dias da semana [fonte](https://blog.learngoprogramming.com/golang-const-type-enums-iota-bc4befd096d3)_
#### Exemplos de Uso no mundo real
No exemplo acima nós criamos duas instâncias de um serviço sem muita função, apenas para demostrar como podemos aplicar diferentes flags e com as opções sendo modificadas de acordo com os valores definidos no seu construtor, eliminando a necessidade de diversas flags boleanas e tornando o conjunto de modificadores expansíveis.
Um exemplo clássico de uso de bitmasking é em sistemas de permissões, onde diferentes níveis de acesso (leitura, escrita, execução) são representados por diferentes bits.
```go
type Permission int
const (
Read Permission = 1 << iota
Write
Execute
)
type User struct {
permissions Permission
}
func (u *User) HasPermission(p Permission) bool {
return u.permissions&p != 0
}
func main() {
user := &User{permissions: Read | Write}
fmt.Println("Can Read:", user.HasPermission(Read))
fmt.Println("Can Write:", user.HasPermission(Write))
fmt.Println("Can Execute:", user.HasPermission(Execute))
}
```
Neste exemplo, podemos ver como é simples e eficiente verificar múltiplas permissões combinando-as em um único valor inteiro.
Vamos supor que eu queira incluir novas permissõs como Delete e Share,
Basta que eu defina novas permissões à minhas constantes:
```go
const (
Read Permission = 1 << iota
Write
Execute
Delete
Share
)
```
Essas permissões ainda podem ser armazenadas em um banco de dados por exemplo
Vamos assumir que temos uma tabela chamada users com um campo permissions que armazena o valor das permissões usando bitmask.
```sql
CREATE TABLE users (
id INTEGER PRIMARY KEY,
name TEXT,
permissions INTEGER
);
```
Como o bitmask é um inteiro, ele será armazenado no banco de dados de forma bem direta, sem muitas complicações, reduzindo tamanhos de tabelas e dados armazenados.
Um Porém cuidado, caso uma permissão seja renomeada ou movida de posição na constante irá mudar o valor inteiro, tornando initulizável o valor armazenado.
No exemplo acima a permissão `Read | Write` irá imprimir o valor inteiro `3`. Porém vamos supor que você queira melhorar a legibilidade do seu código adicionando a primeira declaração do iota como um valor vazio, sumindo um usuário sem permissão alguma.
```go
const (
_ Permission = 1 << iota
Read
Write
Execute
)
```
A permissão ` Read | Write` agorá irá imprimir o valor `10` ao invés de `3`.
##### Exemplo permissões de sistema
Configurações de inicialização ou opções de sistema podem ser combinadas e verificadas usando bitmasking para determinar o comportamento do sistema.
```go
type SystemOption int
const (
EnableLogging SystemOption = 1 << iota
EnableDebugging
EnableMetrics
)
type SystemConfig struct {
options SystemOption
}
func (s *SystemConfig) IsEnabled(option SystemOption) bool {
return s.options&option != 0
}
func main() {
config := &SystemConfig{options: EnableLogging | EnableMetrics}
fmt.Println("Logging Enabled:", config.IsEnabled(EnableLogging))
fmt.Println("Debugging Enabled:", config.IsEnabled(EnableDebugging))
fmt.Println("Metrics Enabled:", config.IsEnabled(EnableMetrics))
}
```
##### Um exemplo um pouco mais avançado...
O uso de bitwise e bitmasking pode ser encontrado em operações de gráficos computacionais, onde frequentemente manipulamos pixels e cores.
Em gráficos computacionais, as cores são frequentemente representadas por valores RGBA (Red, Green, Blue, Alpha), onde cada componente da cor é armazenado em um byte (8 bits). Podemos usar operações bitwise para manipular essas cores.
O exemplo abaixo mostra como um programa que inverte as cores de uma imagem usando operações bitwise.
```go
package main
import (
"image"
"image/color"
"image/draw"
"image/jpeg"
"image/png"
"log"
"os"
)
// Inverte a cor de um pixel usando operações bitwise
func invertColor(c color.Color) color.Color {
r, g, b, a := c.RGBA()
return color.RGBA{
R: uint8(^r >> 8),
G: uint8(^g >> 8),
B: uint8(^b >> 8),
A: uint8(a >> 8), // Alpha não é invertido
}
}
// Função para inverter as cores de uma imagem
func invertImageColors(img image.Image) image.Image {
bounds := img.Bounds()
invertedImg := image.NewRGBA(bounds)
draw.Draw(invertedImg, bounds, img, bounds.Min, draw.Src)
for y := bounds.Min.Y; y < bounds.Max.Y; y++ {
for x := bounds.Min.X; x < bounds.Max.X; x++ {
originalColor := img.At(x, y)
invertedColor := invertColor(originalColor)
invertedImg.Set(x, y, invertedColor)
}
}
return invertedImg
}
func main() {
// Abre o arquivo de imagem
file, err := os.Open("input.png")
if err != nil {
log.Fatalf("failed to open: %s", err)
}
defer file.Close()
// Decodifica a imagem
img, err := png.Decode(file)
if err != nil {
log.Fatalf("failed to decode: %s", err)
}
// Inverte as cores da imagem
invertedImg := invertImageColors(img)
// Salva a imagem invertida
outputFile, err := os.Create("output.png")
if err != nil {
log.Fatalf("failed to create: %s", err)
}
defer outputFile.Close()
err = png.Encode(outputFile, invertedImg)
if err != nil {
log.Fatalf("failed to encode: %s", err)
}
log.Println("Image inversion completed successfully")
}
```
Nesse código a `invertColor` recebe uma cor (color.Color) e inverte seus componentes RGB usando a operação bitwise NOT (^). O componente Alpha (A) não é invertido.
c.RGBA() retorna os componentes de cor como valores de 16 bits (0-65535), por isso os componentes são deslocados 8 bits para a direita (>> 8) para serem convertidos para a faixa de 8 bits (0-255).
#### Desvantagens dessa abodagem
Embora o bitmasking seja extremamente eficiente em termos de desempenho e uso de memória, suas desvantagens em termos de complexidade, legibilidade e manutenção devem ser cuidadosamente consideradas.
- **Complexidade:** Bitmasking pode ser confuso para programadores iniciantes ou para aqueles que não estão familiarizados com operações bitwise. A manipulação de bits diretamente exige uma compreensão sólida de operações binárias.
- **Legibilidade do Código:** O código que utiliza bitmasking pode ser menos legível e intuitivo em comparação com outras abordagens. Por exemplo, verificar se um bit específico está definido pode não ser tão claro quanto verificar um campo booleano em uma estrutura de banco de dados.
- **Manutenção:** Remover as opções ou modificar opções existentes pode ser propenso a erros, especialmente se não houver documentação adequada ou se os valores dos bits não forem gerenciados cuidadosamente.
- **Limitações de Tamanho:** Dependendo do tipo de dado utilizado (por exemplo, int), há um limite no número de flags que podem ser representadas. Por exemplo, um int de 32 bits pode representar até 32 flags diferentes. Isso pode ser uma limitação em sistemas que necessitam de um grande número de opções.
- **Erros Silenciosos:** Erros na manipulação de bits podem ser difíceis de diagnosticar e podem não resultar em falhas imediatas ou óbvias. Por exemplo, definir ou limpar o bit errado pode alterar inadvertidamente múltiplas flags, levando a comportamentos inesperados que podem ser difíceis de rastrear.
#### Conclusão
Bitmasking é uma técnica valiosa para representar e manipular conjuntos de opções de maneira eficiente. Em Go, essa técnica pode ser implementada de forma simples e eficaz, como demonstrado nos exemplos acima. Seja para sistemas de permissões, configurações de sistema ou estados de jogo, bitmasking oferece uma maneira poderosa de gerenciar múltiplas opções com operações bitwise rápidas e eficientes.
Para projetos onde a legibilidade e a facilidade de manutenção são prioridades, ou onde o número de opções é grande, outras técnicas, como estruturas de dados customizadas ou mapas, podem ser mais apropriadas. No entanto, para sistemas onde o desempenho é crítico e o número de opções é manejável, bitmasking continua sendo uma ferramenta poderosa e eficiente.
Se você está vindo de um background em PHP, C, Java ou qualquer outra linguagem, experimentar bitmasking em Go pode oferecer uma nova perspectiva, somando a eficiência e a simplicidade desta técnia ao arsenal de qualquer programador.

Like many... | 0 | 2024-07-12T19:57:23 | https://www.jetify.com/blog/why-we-ditched-vercel-for-our-nodejs-app/ | webdev, javascript, devops, startup | In the world of web development, the search for the ideal hosting solution is never-ending. Like many others, we initially fell in love with Vercel for its user-friendly interface and near-zero setup. Vercel is an excellent solution for static sites, perfect for our websites and documentation. CDN caching makes everything fast, efficient, and cost-effective.
Given our positive experience with Vercel for static sites, we decided to host our NodeJS servers there as well. We had several Remix servers we thought could be supported by edge functions. After all, isn't the future all about going serverless? We decided to host our authentication flow and dashboard app on Vercel using edge functions. Spoiler alert: it did not go well.
## Why Vercel Doesn’t Cut It
### Speed Issues: The Dream Dies
Our first red flag was performance. Serverless functions on Vercel were not up to par in terms of speed. And it wasn’t just us—many developers have voiced [similar frustrations](https://www.reddit.com/r/nextjs/comments/13vi7rz/anyone_else_have_trouble_with_slow_serverless/). For an application handling critical user interactions like authentication, speed is paramount. The delays were noticeable, often around 600ms to 1 second.
### Debugging Nightmares: The Endless Cycles
Vercel detects the framework of your NodeJS server in an attempt to turn each route into an edge function. Server-side libraries may build successfully for edge functions yet encounter issues at runtime without notice. With most bugs not reproducible locally, and the remote environment is not something you can SSH into, endless trial and error becomes the norm. What’s worse, you may find out the package you need is not edge-function compatible at all.
### Cost Explosions: The $96K Surprise
For customers, calculating usage is no longer as simple as total billable hours for a single EC2. To make it more concrete, a single JS server that contains ten routes will split into ten different edge functions. While Vercel gives you uptime and scalability guarantees, a [shocking $96K bill](https://x.com/zemotion/status/1798558292681343039) may knock on your door if you get a spike in usage.
### The bottom line
Going serverless for an app that clearly needs a backend server? In hindsight, that should make us pause for a second. Just because the server is written in JavaScript, does not mean we should treat it differently from a server written in Go, Rust, or Python. The bottom line — infrastructure should be language and framework-agnostic.
## The ultimate dream: an edge-function-like platform for Backend
Without a good substitute for Vercel’s edge functions, we Jetifiers like to build our own.
Introducing [Jetify Deploy](https://www.jetify.com/deploy), a platform that incorporates the best properties of edge-function while avoiding its drawbacks:
1. No Dockerfiles needed: don’t know how to write Dockerfiles or Kubernetes YAMLs? No problem, you don’t have to. However, you can provide a [devbox.json](https://www.jetify.com/devbox/docs/configuration/) or Dockerfile if you want more control.
2. No application code change: there are no special libraries you need to import or hidden route splitting that happens behind the scenes.
3. Zero DevOps: no Terraform, Ansible, or shell scripts needed. Import your application code from GitHub, and we will handle the rest.
4. Stateless: deployments are as disposable assets, not precious pets. Past deployments are kept as idle copies until needed.
5. Easy cost management: Your server spins up when it gets a request and spins down when idle. You won’t get a hundred edge functions just to handle a surge in requests.
6. Write once, run anywhere: wrap your project with [Devbox](https://www.jetify.com/devbox) to get an identical environment for local, preview, and production. Any issues encountered on production can be reproduced locally. Or anywhere.
## Looking ahead
We have successfully migrated our authentication flow and dashboard app from Vercel edge functions to Jetify Cloud. The transition was smooth, and we have seen significant improvements in speed, debuggability, and cost.
We are excited to share our journey and encourage others facing similar challenges to explore new possibilities. You can try Jetify Cloud for your own solo projects with a 30-day free trial. Jetify Cloud accounts also come with access to the [Jetify Cache](https://www.jetify.com/cache), and [Jetify Secrets](https://www.jetify.com/devbox/docs/cloud/secrets):
Stay tuned as we continue to refine our setup and share more insights. If you are struggling with your current hosting solution, we hope our story inspires you to find your perfect fit. You can follow us on [Twitter](https://twitter.com/jetify_com), or chat with our developers live on our [Discord Server](https://discord.gg/jetify).

If you like these kinds of analysis, you should subscribe to the [AImodels.fyi newsletter](https://aimodels.substack.com) or follow me on [Twitter](https://twitter.com/mikeyoung44).*
## Overview
- This paper explores the design and implementation of retrieval-augmented generation-based chatbots, which combine the strengths of language models and information retrieval systems.
- The authors present a case study on building a chatbot that can engage in informed conversations about household electricity monitoring, drawing insights that can be applied more broadly.
- Key topics covered include architectural considerations, data collection and curation, as well as evaluation of the chatbot's performance and user experience.
## Plain English Explanation
The paper discusses how to build chatbots that can engage in more informative and nuanced conversations by combining language generation and information retrieval capabilities. Rather than relying solely on language models to generate responses, these "retrieval-augmented" chatbots can supplement their knowledge by retrieving relevant information from a database.
The authors provide a detailed case study on building a chatbot that can discuss household electricity monitoring. This involves designing the chatbot's architecture to seamlessly integrate language understanding, response generation, and information retrieval. The team also had to carefully collect and curate a knowledge base covering topics related to home electricity usage.
Through user testing and evaluation, the researchers were able to assess the benefits and limitations of their retrieval-augmented approach. The chatbot was able to provide more detailed and accurate information compared to a language model-only system. However, challenges remained in ensuring smooth transitions between retrieved information and generated responses.
The insights from this case study can inform the development of other retrieval-augmented chatbots across different domains. By harnessing both generation and retrieval capabilities, these systems can have more natural and substantive conversations, providing users with more useful and trustworthy information.
## Technical Explanation
The paper presents a case study on building a [retrieval-augmented generation-based chatbot](https://aimodels.fyi/papers/arxiv/survey-rag-meeting-llms-towards-retrieval-augmented) for informed conversations about household electricity monitoring. This builds on prior work on [RAG-enabled conversations](https://aimodels.fyi/papers/arxiv/rag-enabled-conversations-about-household-electricity-monitoring) and [informed question answering](https://aimodels.fyi/papers/arxiv/from-questions-to-insightful-answers-building-informed).
The chatbot's architecture integrates a language model for natural language understanding and response generation, alongside an information retrieval system that can fetch relevant content from a knowledge base. The researchers carefully curated a dataset covering topics like electricity usage, billing, and home appliances to power the retrieval component.
Through user studies, the team evaluated the chatbot's performance in terms of task completion, information quality, and user experience. Compared to a language model-only baseline, the retrieval-augmented system was able to provide more detailed and accurate responses. However, challenges remained in seamlessly blending retrieved information with generated text, as highlighted in prior work on [StackRAG](https://aimodels.fyi/papers/arxiv/stackrag-agent-improving-developer-answers-retrieval-augmented).
The insights from this case study can inform the design of other retrieval-augmented chatbots, balancing the [double-edged sword](https://aimodels.fyi/papers/arxiv/ragged-edges-double-edged-sword-retrieval-augmented) of leveraging both generation and retrieval capabilities.
## Critical Analysis
The paper provides a comprehensive overview of the process involved in building a retrieval-augmented chatbot, addressing key architectural and implementation considerations. The case study on household electricity monitoring is a well-chosen domain that highlights the advantages of the approach, as users often seek specific and factual information that language models alone may struggle to provide.
However, the paper does acknowledge several limitations and areas for further research. For example, the authors note the difficulty in ensuring smooth transitions between retrieved information and generated responses, an issue that has been observed in prior work on [StackRAG](https://aimodels.fyi/papers/arxiv/stackrag-agent-improving-developer-answers-retrieval-augmented). Further advancements in natural language generation and dialogue management may be needed to address this challenge.
Additionally, the evaluation focuses primarily on objective metrics like task completion and information quality, while the assessment of user experience is relatively limited. Future research could delve deeper into understanding the subjective impact of retrieval-augmented chatbots on user satisfaction, trust, and engagement.
Another potential area for exploration is the scalability and adaptability of the approach. The authors note the significant effort required to curate the knowledge base for their case study. Investigating techniques for automated knowledge base construction or dynamic knowledge acquisition could help improve the applicability of retrieval-augmented chatbots to a wider range of domains.
Overall, the paper provides a valuable contribution to the field of conversational AI, demonstrating the potential of combining language generation and information retrieval to build more capable and informative chatbots. The insights and lessons learned can inform future research and development in this area.
## Conclusion
This paper presents a comprehensive case study on the design and implementation of a retrieval-augmented generation-based chatbot for informed conversations about household electricity monitoring. By integrating language understanding, response generation, and information retrieval capabilities, the chatbot was able to provide more detailed and accurate responses compared to a language model-only system.
The key takeaways from this research can inform the development of other retrieval-augmented chatbots across different domains. While challenges remain in seamlessly blending retrieved information with generated text, the overall approach holds promise for building more capable and trustworthy conversational AI systems. As the field continues to evolve, further advancements in areas like natural language generation, dialogue management, and knowledge base construction could unlock even greater potential for these hybrid architectures.

## Overview
- Researchers tested 7 state-of-the-art large language models (LLMs) on a novel benchmark to assess their linguistic capabilities compared to humans
- LLMs performed at chance accuracy and showed significant inconsistencies in their answers, suggesting they lack human-like understanding of language
- The findings challenge the claim that LLMs possess human-level compositional understanding and reasoning, and may be due to their lack of a specialized mechanism for regulating grammatical and semantic information
## Plain English Explanation
Large language models (LLMs) are artificial intelligence systems that can process and generate human-like text. These models have been deployed in a wide range of applications, from clinical assistance to education, leading some to believe they possess human-like language abilities.
However, [the researchers argue that easy skills are often hard for AI systems](https://aimodels.fyi/papers/arxiv/easy-problems-that-llms-get-wrong). To test this, they created a novel benchmark to systematically evaluate the language understanding of 7 leading LLMs. The models were asked a series of comprehension questions based on short texts featuring common linguistic constructions.
Surprisingly, the LLMs performed at random chance accuracy and provided inconsistent answers, even on these seemingly simple tasks. [Their responses showcased distinct errors in language understanding that do not match human capabilities](https://aimodels.fyi/papers/arxiv/can-large-language-models-understand-uncommon-meanings).
The researchers interpret these findings as evidence that current LLMs, despite their usefulness in many applications, fall short of truly understanding language in the way humans do. [They suggest this may be due to a lack of specialized mechanisms for regulating grammatical and semantic information](https://aimodels.fyi/papers/arxiv/beyond-accuracy-evaluating-reasoning-behavior-large-language).
## Technical Explanation
The researchers systematically evaluated 7 state-of-the-art LLMs on a novel benchmark designed to assess their linguistic capabilities. The models were presented with a series of comprehension questions based on short texts featuring common grammatical constructions. Participants could respond with either one-word or open-ended answers.
To establish a baseline for human-like performance, the researchers also tested 400 human participants on the same prompts. The study generated a dataset of 26,680 datapoints, which the researchers analyzed to compare the models' and humans' responses.
The results showed that the LLMs performed at chance accuracy and exhibited significant inconsistencies in their answers, even on these seemingly simple language tasks. [Qualitatively, the models' responses showcased distinct errors that do not align with human language understanding](https://aimodels.fyi/papers/arxiv/assessing-nature-large-language-models-caution-against).
The researchers interpret these findings as a challenge to the claim that LLMs possess human-like compositional understanding and reasoning abilities. [They suggest the models' limitations may be due to a lack of specialized mechanisms for regulating grammatical and semantic information, a phenomenon known as Moravec's Paradox](https://aimodels.fyi/papers/arxiv/are-large-language-models-superhuman-chemists).
## Critical Analysis
The researchers acknowledge that their results do not imply LLMs are inherently incapable of language understanding. They note that the models may perform better on different tasks or with further training and refinement.
However, the findings do challenge the common perception that these models possess human-like linguistic capabilities. The researchers argue that their systematic evaluation reveals fundamental limitations in the way LLMs process and comprehend language, which may be rooted in the models' underlying architecture and training approaches.
While the paper provides valuable insights, it is essential to consider the potential biases and limitations of the study. The benchmark used may not capture the full breadth of linguistic phenomena, and the performance of the models may vary depending on the specific task or dataset.
Additionally, the researchers' interpretation of the results, while plausible, could be further explored and validated through additional research. Investigating the role of specialized mechanisms for regulating grammatical and semantic information, as well as exploring alternative architectural approaches, could shed more light on the nature of language understanding in LLMs.
## Conclusion
This study presents compelling evidence that current state-of-the-art large language models (LLMs) fall short of matching human-like language understanding, despite their widespread deployment in various applications. The systematic evaluation revealed significant inconsistencies and poor performance in the models' responses to simple comprehension tasks, suggesting their language capabilities are not as advanced as commonly believed.
The researchers' interpretation of these findings, rooted in Moravec's Paradox, offers a thought-provoking perspective on the limitations of LLMs. Their work challenges the notion that these models possess human-level compositional understanding and reasoning, and highlights the need for further research into the underlying mechanisms required for true language mastery.
As the field of natural language processing continues to evolve, this study serves as a cautionary tale, reminding us that achieving human-like linguistic capabilities in AI remains an elusive and complex challenge. The insights gained from this research can inform the development of more robust and meaningful language models, ultimately advancing our understanding of the nature of human language and cognition.

## Overview
- Diffusion models have shown impressive performance in various image generation, editing, enhancement, and translation tasks.
- Stable diffusion models, in particular, offer a potential solution to the challenging problems of realistic image super-resolution (Real-ISR) and image stylization.
- However, existing methods often fail to preserve faithful pixel-wise image structures.
- This paper proposes a Pixel-Aware Stable Diffusion (PASD) network to achieve robust Real-ISR and personalized image stylization.
## Plain English Explanation
Diffusion models are a type of machine learning algorithm that can generate and manipulate images. These models have become quite good at tasks like creating new images from scratch, improving the quality of existing images, and even changing the style of an image to make it look like it was painted in a particular artistic style.
The researchers in this paper focused on two specific challenges: realistic image super-resolution (Real-ISR) and image stylization. Real-ISR is the process of taking a low-quality image and generating a higher-quality version of it, while preserving the important details. Image stylization is the task of taking an image and making it look like it was created in a certain artistic style, such as impressionism or expressionism.
The researchers found that while existing diffusion models can be used for these tasks, they often struggle to maintain the fine-level details in the images. To address this, the researchers developed a new model called Pixel-Aware Stable Diffusion (PASD). PASD has a few key innovations:
1. A "pixel-aware cross attention module" that helps the model understand the local structure of the image at the pixel level.
2. A "degradation removal module" that extracts features from the image that are less sensitive to image quality issues, to help guide the diffusion process.
3. An "adjustable noise schedule" that further improves the image restoration results.
By using PASD, the researchers were able to generate high-quality images for both Real-ISR and image stylization, while preserving important details. This could be useful for a variety of applications, such as photo editing, digital art creation, and image enhancement.
## Technical Explanation
The paper proposes a Pixel-Aware Stable Diffusion (PASD) network to address the limitations of existing methods in achieving robust [Real-ISR](https://aimodels.fyi/papers/arxiv/exploiting-diffusion-prior-real-world-image-super) and personalized [image stylization](https://aimodels.fyi/papers/arxiv/towards-highly-realistic-artistic-style-transfer-via).
The key innovations of PASD include:
1. **Pixel-Aware Cross Attention Module**: This module enables the diffusion model to perceive image local structures at the pixel level, helping to preserve important details during the generation process.
2. **Degradation Removal Module**: This module extracts degradation-insensitive features from the input image, which are then used to guide the diffusion process along with the high-level image information.
3. **Adjustable Noise Schedule**: An adjustable noise schedule is introduced to further improve the image restoration results.
The PASD network can be used for both Real-ISR and image stylization tasks. For Real-ISR, PASD can generate high-quality, detailed images from low-resolution inputs. For image stylization, PASD can generate diverse stylized images by simply replacing the base diffusion model with a stylized one, without the need for pairwise training data.
The researchers evaluate PASD on a variety of image enhancement and stylization tasks, and demonstrate its effectiveness compared to existing methods. The source code for PASD is available on [GitHub](https://github.com/yangxy/PASD/).
## Critical Analysis
The paper presents a promising approach to addressing the challenges of realistic image super-resolution and personalized image stylization using diffusion models. The key innovations, such as the pixel-aware cross attention module and the degradation removal module, seem well-designed to help the diffusion model better preserve image details and structures.
One potential limitation of the paper is that it does not provide a thorough analysis of the computational and memory requirements of the PASD network, which could be important for real-world applications. Additionally, the paper could have explored the model's performance on a wider range of image domains and stylization tasks to further demonstrate its versatility.
It would also be interesting to see how PASD compares to other state-of-the-art approaches in this domain, such as [One-Step Effective Diffusion Network for Real-World](https://aimodels.fyi/papers/arxiv/one-step-effective-diffusion-network-real-world), [Exploiting Diffusion Prior for Real-World Image Super-Resolution](https://aimodels.fyi/papers/arxiv/exploiting-diffusion-prior-real-world-image-super), and [PatchScaler: Efficient Patch-Independent Diffusion Model for Super-Resolution](https://aimodels.fyi/papers/arxiv/patchscaler-efficient-patch-independent-diffusion-model-super). Further research could investigate the potential synergies between these different approaches.
Overall, the PASD network presented in this paper represents a promising step forward in the application of diffusion models to challenging image enhancement and stylization tasks, and the researchers' work is a valuable contribution to the field of [diffusion-based image generation](https://aimodels.fyi/papers/arxiv/discffusion-discriminative-diffusion-models-as-few-shot).
## Conclusion
This paper introduces the Pixel-Aware Stable Diffusion (PASD) network, a novel approach to achieving robust realistic image super-resolution and personalized image stylization using diffusion models. The key innovations, such as the pixel-aware cross attention module and the degradation removal module, enable PASD to preserve important image details and structures during the generation process.
The researchers demonstrate the effectiveness of PASD through extensive experiments on a variety of image enhancement and stylization tasks. This work represents an important advancement in the application of diffusion models to challenging real-world image processing problems, and could have significant implications for a range of applications, from photo editing and digital art creation to image restoration and enhancement.

## Overview
- The paper explores a control theory approach to prompting large language models (LLMs) like GPT-3 and ChatGPT.
- It investigates how different prompting strategies can be used to control the behavior and output of LLMs.
- The authors propose a framework for analyzing and optimizing prompts as a control system.
## Plain English Explanation
The paper looks at how we can use prompts to "control" the behavior of large language models like GPT-3 and ChatGPT. Prompts are the instructions or questions we give these models to get them to produce a desired output.
The researchers suggest we can think of prompt engineering as a control system. Just like an engineer might design a controller to regulate the temperature or speed of a physical system, the researchers say we can design prompts to regulate the behavior of language models.
For example, we might use a prompt to get a language model to write a creative story, answer a specific question, or generate text in a particular style. The paper explores different prompt design strategies and how they impact the model's behavior and output.
The key idea is that prompts act like a "control input" that allows us to steer the language model in the direction we want, similar to how a engineer might use a control input to regulate a physical system. The paper provides a framework for analyzing and optimizing prompts from this control theory perspective.
## Technical Explanation
The paper introduces a control theory approach to prompting large language models (LLMs) like GPT-3 and ChatGPT. It frames prompt engineering as a control system, where the prompt acts as the control input that shapes the behavior and output of the language model.
The authors propose a framework for modeling prompts as a control system. They define the language model as the "plant" that is being controlled, and the prompt as the control input that shapes the model's behavior. They then analyze different prompt design strategies in terms of their effects on the control system.
The paper explores several prompt optimization techniques, including:
1. **The AutoPrompt Family:** Methods that automatically generate or optimize prompts to achieve specific objectives, such as improving task performance or controlling the sentiment/style of the output.
2. **Other Prompt Optimization Methods:** Techniques that leverage reinforcement learning, constraint-based optimization, or other approaches to find prompts that steer the language model in desired directions.
Through this control theory lens, the authors provide insights into how prompt design impacts the stability, controllability, and performance of LLMs. They discuss the implications of their framework for prompt engineering and the broader challenge of controlling the behavior of powerful language models.
## Critical Analysis
The control theory framing proposed in the paper provides a valuable perspective for understanding and optimizing prompt design. By modeling prompts as control inputs, the authors offer a systematic way to analyze and reason about how different prompt strategies impact language model behavior.
However, the paper also acknowledges several limitations and caveats to this approach. For example, the authors note that language models are complex, nonlinear systems that may not always behave predictably under different prompting strategies. Additionally, the control theory framework may not fully capture the nuances of language and semantics that influence model outputs.
Furthermore, the paper does not address potential safety or ethical concerns that may arise from the ability to precisely control the outputs of powerful language models. As prompt engineering techniques become more sophisticated, there are important questions to consider around the responsible development and deployment of such systems.
Overall, the control theory approach presented in the paper offers a promising framework for prompt engineering, but continued research is needed to fully understand the capabilities and limitations of this technique, as well as its societal implications.
## Conclusion
This paper introduces a control theory perspective on prompting large language models, framing prompt engineering as a control system problem. The authors propose a framework for modeling prompts as control inputs that shape the behavior and outputs of LLMs like GPT-3 and ChatGPT.
By analyzing different prompt optimization techniques through this control theory lens, the paper provides insights into how prompt design impacts the stability, controllability, and performance of language models. This work offers a systematic approach to prompt engineering and highlights the potential for using control theory to better understand and harness the capabilities of powerful language models.
While the control theory framework has limitations, it represents an important step towards developing more principled and predictable methods for interacting with and controlling the behavior of large language models. As these models become increasingly influential, research like this will be crucial for ensuring they are developed and deployed responsibly.

If you like these kinds of analysis, you should subscribe to the [AImodels.fyi newsletter](https://aimodels.substack.com) or follow me on [Twitter](https://twitter.com/mikeyoung44).*
## Overview
- This paper introduces a novel approach called MoE-LLaVA (Mixture of Experts for Large Vision-Language Models) to improve the performance and efficiency of large vision-language models.
- The key idea is to use a Mixture of Experts (MoE) architecture, where the model is divided into multiple specialized "experts" that work together to process inputs more effectively.
- This contrasts with traditional "one-size-fits-all" models that try to handle all tasks and inputs with a single monolithic architecture.
## Plain English Explanation
The researchers propose a new way to build large vision-language models that can handle a wide variety of tasks and inputs more effectively. Instead of having a single, generic model try to do everything, they split the model into multiple "experts" - specialized sub-models that each focus on a particular type of task or input.
When presented with a new input, the model dynamically selects the most appropriate experts to process it, rather than forcing the whole model to handle everything. This [Mixture of Experts (MoE) approach](https://aimodels.fyi/papers/arxiv/toward-inference-optimal-mixture-expert-large-language) allows the model to leverage the strengths of different sub-components, leading to improved performance and efficiency.
The researchers show that this MoE-LLaVA architecture outperforms traditional large vision-language models on a range of benchmarks, demonstrating the benefits of this modular, specialized approach. This builds on prior work exploring [MoE techniques for scaling up language models](https://aimodels.fyi/papers/arxiv/dense-training-sparse-inference-rethinking-training-mixture) and [applying MoE to multimodal tasks](https://aimodels.fyi/papers/arxiv/uni-moe-scaling-unified-multimodal-llms-mixture).
## Technical Explanation
The core idea behind MoE-LLaVA is to leverage a [Mixture of Experts (MoE)](https://aimodels.fyi/papers/arxiv/toward-inference-optimal-mixture-expert-large-language) architecture to improve the performance and efficiency of large vision-language models. In a traditional monolithic model, a single architecture is tasked with handling all inputs and tasks. In contrast, MoE-LLaVA divides the model into multiple specialized "expert" sub-models, each of which is trained to excel at a particular type of input or task.
When presented with a new input, the MoE-LLaVA model dynamically selects the most appropriate experts to process it, rather than forcing the entire model to handle everything. This allows the model to leverage the strengths of different sub-components, leading to improved performance and efficiency. The researchers show that this approach outperforms traditional large vision-language models on a range of benchmarks.
The MoE-LLaVA architecture builds on prior work exploring the use of [MoE techniques for scaling up language models](https://aimodels.fyi/papers/arxiv/dense-training-sparse-inference-rethinking-training-mixture) and [applying MoE to multimodal tasks](https://aimodels.fyi/papers/arxiv/uni-moe-scaling-unified-multimodal-llms-mixture). By adapting these ideas to the vision-language domain, the researchers demonstrate the potential of MoE approaches to enhance the capabilities of large multimodal models.
## Critical Analysis
The researchers provide a thorough evaluation of the MoE-LLaVA approach, including comparisons to state-of-the-art vision-language models on a variety of benchmarks. The results are compelling, showing clear performance improvements across multiple tasks.
However, the paper does not delve deeply into the potential limitations or downsides of the MoE-LLaVA approach. For example, it is unclear how the model's complexity and training requirements scale as the number of experts increases, or how the expert selection process might impact interpretability and transparency.
Additionally, while the paper discusses the benefits of the MoE architecture, it does not provide much insight into how the individual expert models are trained or how their specializations emerge. More details on the training process and the factors that influence expert specialization could help readers better understand the inner workings of the model.
Overall, the MoE-LLaVA approach appears to be a promising direction for improving the performance and efficiency of large vision-language models. However, further research is needed to fully understand the tradeoffs and limitations of this approach, as well as its broader implications for the development of advanced multimodal AI systems.
## Conclusion
The MoE-LLaVA paper introduces a novel approach to enhancing the capabilities of large vision-language models by leveraging a Mixture of Experts (MoE) architecture. This modular, specialized design allows the model to dynamically select the most appropriate sub-components to process each input, leading to improved performance and efficiency compared to traditional monolithic models.
The researchers demonstrate the effectiveness of the MoE-LLaVA approach through extensive benchmarking, showing that it outperforms state-of-the-art vision-language models on a range of tasks. This work builds on previous advancements in using MoE techniques to scale up language models and apply them to multimodal domains.
While the paper provides a compelling proof-of-concept, further research is needed to fully understand the tradeoffs and limitations of the MoE-LLaVA approach. Nonetheless, this research represents an important step forward in the development of more capable and efficient large-scale vision-language models, with potential implications for a wide range of AI applications.

## Overview
- This paper introduces Toto, a Time Series Optimized Transformer for Observability, a new deep learning model designed to efficiently process and analyze time series data for observability tasks.
- Observability data, such as metrics, logs, and traces, is critical for understanding the performance and health of complex systems, but can be challenging to work with due to its high-dimensional, sequential nature.
- Toto aims to address these challenges by leveraging the power of Transformer models, which have shown great success in a variety of sequence-to-sequence tasks.
## Plain English Explanation
[Toto: Time Series Optimized Transformer for Observability](https://aimodels.fyi/papers/arxiv/unified-training-universal-time-series-forecasting-transformers) is a new deep learning model that is designed to work with time series data, which is a type of data that changes over time. This kind of data is really important for understanding how complex systems, like software or machines, are performing and if they're healthy.
The problem is that time series data can be tricky to work with because it's very high-dimensional (meaning it has a lot of different measurements) and it's sequential (meaning the measurements happen one after the other in a specific order). This makes it hard for traditional machine learning models to process and understand.
To solve this problem, the researchers behind Toto used a special kind of deep learning model called a Transformer. [Transformers](https://aimodels.fyi/papers/arxiv/tsgt-stochastic-time-series-modeling-transformer) have been really successful at working with all kinds of sequential data, like language and speech. The researchers thought that Transformers could also be great at working with time series data, so they designed Toto to take advantage of Transformer's strengths.
The key idea behind Toto is to optimize the Transformer model specifically for time series data, so that it can extract the most important information and patterns from the data really efficiently. This means that Toto can help us better understand the performance and health of complex systems, which is super important for things like monitoring and troubleshooting.
## Technical Explanation
[Toto](https://aimodels.fyi/papers/arxiv/unified-training-universal-time-series-forecasting-transformers) is a novel deep learning model that leverages the power of Transformer architectures to tackle the unique challenges of time series data for observability tasks.
Observability data, such as metrics, logs, and traces, is critical for understanding the performance and health of complex systems. However, this data is inherently high-dimensional and sequential, making it difficult for traditional machine learning models to effectively process and extract meaningful insights.
To address these challenges, the researchers behind Toto designed a Transformer-based architecture that is specifically optimized for time series data. Unlike general-purpose Transformer models, Toto incorporates several key innovations:
1. **Time-aware Positional Encoding**: Toto uses a custom positional encoding scheme that captures the temporal relationships within the time series data, allowing the model to better understand the sequential nature of the inputs.
2. **Temporal Attention Mechanism**: Toto's attention mechanism is tailored to focus on the temporal dependencies in the data, rather than treating all time steps equally, as in a standard Transformer.
3. **Multi-Task Learning**: Toto is trained on a suite of observability-related tasks, such as anomaly detection, forecasting, and root cause analysis, allowing the model to learn a more generalizable representation of the data.
The researchers evaluated Toto on a diverse range of real-world observability datasets and found that it outperformed state-of-the-art time series models across multiple metrics and tasks. This demonstrates the power of Toto's specialized design and the benefits of using Transformer-based architectures for complex time series analysis.
## Critical Analysis
The researchers behind Toto have made a compelling case for the advantages of their model, but there are a few potential limitations and areas for further exploration:
1. **Interpretability**: While Toto's specialized Transformer architecture may lead to improved performance, the inherent complexity of the model could make it more difficult to interpret and understand the underlying reasons for its predictions. Addressing the interpretability of Toto's decision-making process could be an important area for future research.
2. **Scalability**: The researchers tested Toto on a range of datasets, but it's unclear how the model would scale to truly massive, real-world observability datasets. Evaluating Toto's performance and efficiency on large-scale, production-level data could be a valuable next step.
3. **Generalization**: The researchers focused on demonstrating Toto's effectiveness on observability-related tasks, but it would be interesting to see how the model performs on a broader range of time series problems, such as [forecasting](https://aimodels.fyi/papers/arxiv/chronos-learning-language-time-series) or [time-series-to-text generation](https://aimodels.fyi/papers/arxiv/timegpt-1). Exploring Toto's generalization capabilities could uncover additional use cases for the model.
4. **Real-world Deployment**: While the researchers have shown Toto's potential in a research setting, the true value of the model will be in its ability to be effectively deployed and integrated into real-world observability systems. Evaluating the practical challenges and considerations around deploying Toto in production environments would be a valuable next step.
Overall, the Toto model represents an exciting advancement in the field of time series analysis and observability, and the researchers have done a commendable job in demonstrating its capabilities. By continuing to explore the model's limitations and expanding its applications, the researchers could further strengthen the impact of their work.
## Conclusion
[Toto: Time Series Optimized Transformer for Observability](https://aimodels.fyi/papers/arxiv/decoder-only-foundation-model-time-series-forecasting) is a novel deep learning model that leverages the power of Transformer architectures to tackle the unique challenges of time series data for observability tasks. By incorporating specialized design choices, such as time-aware positional encoding and a tailored attention mechanism, Toto is able to outperform state-of-the-art time series models on a range of real-world observability datasets.
The researchers' work demonstrates the benefits of using Transformer-based models for complex time series analysis and highlights the importance of optimizing these models for the specific characteristics of the data. As the demand for effective observability tools continues to grow, Toto's ability to extract meaningful insights from high-dimensional, sequential data could have significant implications for the monitoring and troubleshooting of complex systems.
While the Toto model shows promise, there are still opportunities for further research and improvement, such as enhancing the model's interpretability, evaluating its scalability and generalization capabilities, and exploring the practical challenges of deploying it in real-world observability systems. By addressing these areas, the researchers could further strengthen the impact of their work and contribute to the ongoing advancement of time series analysis and observability technologies.

1,921,588 | Data Gourmetization and LinkedIners 👨🍳 | Every new year I see companies trying to invent new processes, strategies and technologies, over and... | 0 | 2024-07-12T21:51:13 | https://dev.to/data_baker/data-gourmetization-1k0l | career, data, database, ai | Every new year I see companies trying to invent new processes, strategies and technologies, over and over again, gourmetizing data roles, to try to minimize the efforts of working with their messy data stored with no actual purpose through all kinds of monstruous apps just to make it profitable for any person that will buy the idea that this might generate value to their business - most of the times, with no success. Come on, I’m sure you might have heard: “Data is the new oil”.
But why? And what does it have to do with the gourmetization of data and data roles?
Well, first, let me tell you something... Having a PowerBI with glowing pizza charts or having your PostgreSQL view running in less than 10s is not enough to make your data useful. Now, let me explain why.
<br/>
### **Ok, but what is data gourmetization?**
Yes, I came up with this word, but to help you understand my line of thought, just search the LinkedIn app in your phone (or browser), execute it and start scrolling.
Voilá, if you're a data analyst, data scientist, data engineer or have any other data-janitor role, within the first minute navigating in the platform you will definitely see at least one post talking about neon dashboard designs or why being a data analyst is so important for a company (and sometimes very trustful popups of courses on how to become a data analyst in 3 months which I would highly recommend trying - I'm kidding, don't do that).
<br/><br/>
### **Why new strategies doesn't help?**
Well, that part is not entirely true. If you know what you are doing, and most importantly, why you are doing, then it will surely help (a lot).
But what are the LinkedIners forgetting? Simple. To sit down with their clients (or internal stakeholders) and evaluate what their business need to look at. No confusion matrix, no random forest, no PowerBI glowing dashboard. For more than 70% of the cases I've worked throughout my career, only an e-mail with some KPIs or an excel file that I extracted with a simple select query solved their issue.
Now... let's go more technical.
<br/><br/>
### **What actually helps (technically)**
The vast majority of the data issues we have today regarding storage, optimization and architecture can be easily solved with the most basic concepts you can remember of - the ones you (probably) learned early in your graduation and that you are most likely not using in your day-to-day work. Normalization, indexing, entity models, scalable ETL processes, and other basic techniques are key to make your life easier without depending on expensive 3rd party platforms that you will pay tons of dollars to do for you.
<br/>
### Why companies are gourmetizing data, then?
The reasons behind that might be simpler than you think.
- **Attracting Talent:** Calling it "Data Wrangling 2.0" instead of "Basic ETL" sounds way more exciting and is more likely to attract the bright-eyed with anime profile pictures next-gen analysts.
- **Securing Funding:** Investors love innovation. They’re more likely to fund a "next-gen data synthesis platform" than a "robust data cleaning tool," even if they don't understand that they mean the same thing.
- **Creating Hype:** Let’s be honest, hype sells. New terms and concepts generate buzz and keep the tech industry shining and forward-looking.
- **Making money (a lot):** with the right marketing, big hype and investors that exerce big influence in the tech market, anyone can become a new millionaire (or billionare). Just look at the Theranos case, where they raised over $700 million based on promises that turned out to be hollow.
<br/>
### So...?
The truth is... working with data is not that shiny. Every data you show, can and will be negative to the company's profitability if you don't do your job right. So, NO! working with data is not gourmet and you cannot become an analyst in 3 months - and I'm not saying it because of the companies, but that is risky for you as an employee since you might respond for those mistakes as an individual.
All in all, be careful with PowerBI courses, my friend.
Cheers.

If you like these kinds of analysis, you should subscribe to the [AImodels.fyi newsletter](https://aimodels.substack.com) or follow me on [Twitter](https://twitter.com/mikeyoung44).*
## Overview
- As the size of large language models continues to grow, so does the computational resources required to run them.
- Spiking Neural Networks (SNNs) offer an energy-efficient approach to deep learning by using sparse and event-driven activations to reduce computational overhead.
- SNNs have become competitive with non-spiking models on computer vision tasks, but have proven more challenging to train, resulting in performance lags compared to modern deep learning.
- The effectiveness of SNNs in language generation has yet to be fully explored.
## Plain English Explanation
Large language models, which are AI systems that can understand and generate human-like text, require a lot of computing power to run. **[Spiking Neural Networks (SNNs)](https://aimodels.fyi/papers/arxiv/spiking-convolutional-neural-networks-text-classification)** offer a potential solution by using a different type of "neuron" that is more energy-efficient. These neurons only "fire" (activate) when they need to, rather than constantly running like in traditional neural networks.
While SNNs have shown promising results in computer vision tasks, they have been more difficult to train effectively. This has meant their performance hasn't quite caught up to modern deep learning models. Researchers are still exploring how well SNNs can work for language generation tasks, like writing text.
In this paper, the authors take inspiration from the **[RWKV language model](https://aimodels.fyi/papers/arxiv/spikellm-scaling-up-spiking-neural-network-to)** and develop a new SNN-based language model called **SpikeGPT**. They trained two versions of SpikeGPT, one with 45 million parameters and one with 216 million parameters, making it the largest SNN language model trained to date.
The key innovation is that the authors modified the standard transformer architecture to use a more efficient attention mechanism. This allows SpikeGPT to process input tokens sequentially, like a typical SNN, while maintaining competitive performance with non-spiking models.
## Technical Explanation
The authors were inspired by the **[RWKV language model](https://aimodels.fyi/papers/arxiv/spikellm-scaling-up-spiking-neural-network-to)** and developed **SpikeGPT**, a generative language model that uses binary, event-driven spiking activation units. They trained two versions of the model, one with 45 million parameters and one with 216 million parameters, making SpikeGPT the largest backpropagation-trained SNN model to date.
To achieve this, the authors modified the standard transformer architecture to replace the multi-head self-attention mechanism with a more efficient approach. Instead of the quadratic computational complexity (O(N^2)) of typical attention, their approach has linear complexity (O(N)) as the sequence length increases. This allows input tokens to be streamed in sequentially, as is typical for SNNs.
The authors' preliminary experiments show that SpikeGPT remains competitive with non-spiking models on tested benchmarks, while using 20 times fewer operations when processed on neuromorphic hardware that can leverage the sparse, event-driven activations of the SNN architecture.
## Critical Analysis
The authors demonstrate that it is possible to train large-scale SNN language models that can compete with traditional deep learning approaches. This is an important step forward, as SNNs offer the potential for significant energy savings when deployed on specialized neuromorphic hardware.
However, the authors acknowledge that SNN models are still more challenging to train than non-spiking models, and their performance still lags behind the current state-of-the-art. **[Further research is needed to improve the training and performance of SNN language models](https://aimodels.fyi/papers/arxiv/spikellm-scaling-up-spiking-neural-network-to)**, as well as to explore their suitability for a wider range of natural language processing tasks beyond just generation.
Additionally, the paper does not provide a detailed analysis of the energy efficiency benefits of SpikeGPT compared to non-spiking models. **[More work is needed to quantify the real-world energy savings and practical deployment considerations of SNN-based language models](https://aimodels.fyi/papers/arxiv/natural-language-to-verilog-design-recurrent-spiking)**.
## Conclusion
In this paper, the authors have made an important contribution by developing **SpikeGPT**, the largest backpropagation-trained SNN language model to date. By modifying the transformer architecture to use a more efficient attention mechanism, they have demonstrated that SNN-based language models can achieve competitive performance with traditional deep learning approaches.
The potential energy efficiency benefits of SNN models, if they can be further developed and deployed, could have significant implications for the deployment of large language models in real-world applications, particularly on resource-constrained devices. **[As the field of [Spike-based Computation](https://aimodels.fyi/papers/arxiv/spike-based-computation-using-classical-recurrent-neural) continues to advance, we may see more SNN-based models emerge as viable alternatives to traditional deep learning for natural language processing and beyond](https://aimodels.fyi/papers/arxiv/spikelm-towards-general-spike-driven-language-modeling)**.

## Overview
- This paper explores the use of large language models (LLMs) for leaderboard extraction from technical papers.
- The researchers evaluate the performance of various LLM architectures, including [Evaluating Large Language Models for Public Health Classification](https://aimodels.fyi/papers/arxiv/evaluating-large-language-models-public-health-classification), [Can Large Language Models Automatically Score Proficiency](https://aimodels.fyi/papers/arxiv/can-large-language-models-automatically-score-proficiency), and [Apprentices to Research Assistants](https://aimodels.fyi/papers/arxiv/apprentices-to-research-assistants-advancing-research-large), on the task of extracting leaderboard information from research paper text.
- The goal is to determine the most effective LLM-based approach for automating the extraction of leaderboard data, which is an important task for researchers and practitioners in the field.
## Plain English Explanation
The paper looks at using large language models (LLMs) - powerful AI systems that can understand and generate human-like text - to automatically extract leaderboard information from research papers. Leaderboards are tables or lists that show the top-performing methods or systems for a particular task or dataset, and they're commonly found in AI and machine learning papers.
The researchers test different LLM architectures, including some that have been used for other text-related tasks like [classifying public health information](https://aimodels.fyi/papers/arxiv/evaluating-large-language-models-public-health-classification) and [automatically scoring language proficiency](https://aimodels.fyi/papers/arxiv/can-large-language-models-automatically-score-proficiency). They want to see which LLM works best at finding and extracting the leaderboard information from the research paper text.
This is an important task because manually finding and extracting leaderboard data can be time-consuming, especially as the volume of AI and machine learning research continues to grow. If an LLM-based system can do this automatically, it could save researchers a lot of time and effort, allowing them to focus more on the actual research and innovations.
## Technical Explanation
The paper evaluates the performance of several LLM architectures, including [GPT-3](https://aimodels.fyi/papers/arxiv/exploring-use-large-language-model-data-extraction), BERT, and RoBERTa, on the task of extracting leaderboard information from research paper text. The researchers curate a dataset of research papers containing leaderboards and use it to fine-tune and evaluate the LLMs.
The LLMs are tasked with identifying the leaderboard sections in the paper text, extracting the relevant information (e.g., metric names, system names, scores), and structuring the data in a tabular format. The performance of the models is assessed using metrics like precision, recall, and F1 score.
The results show that fine-tuned LLMs, particularly RoBERTa, can achieve strong performance on the leaderboard extraction task, outperforming rule-based and traditional machine learning approaches. The paper also explores the impact of different fine-tuning strategies and the generalization of the LLM-based approach to papers from various domains.
## Critical Analysis
The paper provides a thorough evaluation of LLM-based approaches for leaderboard extraction and offers valuable insights for researchers and practitioners working on automating this task. However, it's important to note a few caveats and limitations:
- The dataset used for fine-tuning and evaluation, while curated with care, may not be fully representative of the diverse range of leaderboard formats and styles found in the broader research literature. Further testing on a larger and more diverse dataset would help validate the generalization of the LLM-based approach.
- The paper does not explore the performance of the LLMs on more complex or ambiguous leaderboard structures, such as those that are spread across multiple tables or sections within a paper. Addressing these more challenging cases could further improve the practical applicability of the approach.
- While the LLM-based methods outperform rule-based and traditional machine learning approaches, there may still be room for improvement in terms of accuracy and robustness. Exploring hybrid approaches that combine the strengths of LLMs with domain-specific knowledge or other techniques could lead to further advancements in this area.
- The paper does not delve into the ethical implications of automating leaderboard extraction, such as the potential for misuse or the impact on research transparency and accountability. These are important considerations that should be addressed in future work.
## Conclusion
This paper presents a promising approach for automating the extraction of leaderboard information from research papers using large language models. The results demonstrate the effectiveness of fine-tuned LLMs, particularly RoBERTa, in identifying and structuring leaderboard data, which could significantly streamline the research process and facilitate more comprehensive and up-to-date comparisons of research systems.
While the paper highlights the potential of LLM-based methods, it also acknowledges the need for further work to address the limitations and explore the broader implications of this technology. As the field of AI continues to evolve, the ability to efficiently and accurately extract and synthesize key information from the growing body of research literature will become increasingly valuable for researchers, practitioners, and the wider scientific community.

## Overview
- Explores how generative AI is impacting online communities and the experiences of community moderators
- Focuses on Reddit moderators' attitudes towards AI-generated content (AIGC) and how their communities are responding
- Finds that communities are enacting rules to restrict AIGC use for ideological and practical reasons
- Highlights the challenges moderators face in detecting and enforcing AIGC restrictions, and the importance of supporting community autonomy
## Plain English Explanation
Generative AI, such as [chatbots](https://aimodels.fyi/papers/arxiv/can-language-model-moderators-improve-health-online) and [content-generating algorithms](https://aimodels.fyi/papers/arxiv/bias-ai-generated-content-examination-news-produced), is starting to have a significant impact on how we work, learn, communicate, and participate in online communities. This study explored how these changes are affecting online communities, focusing specifically on the experiences of community moderators on the social sharing site Reddit.
The researchers conducted in-depth interviews with 15 Reddit moderators to understand their attitudes towards AIGC and how their communities are responding to this new technology. They found that many communities are choosing to enact rules restricting the use of AIGC, both for ideological reasons (e.g., preserving authenticity and transparency) and practical reasons (e.g., limiting disruption and misinformation).
Despite the lack of foolproof tools for detecting AIGC, the moderators were able to somewhat limit the disruption caused by this new phenomenon by working with their communities to clarify norms and expectations around AIGC use. However, they found enforcing these restrictions challenging, as they had to rely on time-intensive and often inaccurate detection methods.
The study highlights the importance of supporting community autonomy and self-determination in the face of these technological changes. It suggests that potential design solutions, such as improved AIGC detection tools or community-driven moderation approaches, could help address the challenges faced by online communities.
## Technical Explanation
The researchers performed 15 in-depth, semi-structured interviews with community moderators on the social sharing site Reddit to understand their attitudes towards AI-generated content (AIGC) and how their communities are responding to this new phenomenon.
The study found that many communities are choosing to enact rules restricting the use of AIGC, both for ideological reasons (e.g., preserving authenticity and transparency) and practical reasons (e.g., limiting disruption and misinformation). Despite the absence of foolproof tools for detecting AIGC, moderators were able to somewhat limit the disruption caused by this new technology by working with their communities to clarify norms about AIGC use.
However, the researchers found that enforcing AIGC restrictions was challenging for moderators, who had to rely on time-intensive and inaccurate detection heuristics in their efforts. The study highlights the importance of supporting community autonomy and self-determination in the face of this sudden technological change, and suggests potential design solutions, such as improved AIGC detection tools or community-driven moderation approaches, that may help address the challenges faced by online communities.
## Critical Analysis
The study provides valuable insights into how online communities are grappling with the emergence of generative AI and the challenges faced by community moderators. However, the research is limited to a single platform (Reddit) and a relatively small sample size of 15 moderators. It would be interesting to see how the experiences and responses of moderators on other online platforms, with different community dynamics and moderation approaches, compare to the findings of this study.
Additionally, the paper does not delve deeply into the potential long-term implications of AIGC on online communities. As the technology continues to evolve and become more sophisticated, the challenges faced by moderators may become increasingly complex. Further research is needed to explore the broader societal and ethical implications of generative AI's impact on online discourse and community-building.
Despite these limitations, the study offers important lessons for platform designers, policymakers, and community leaders on the importance of supporting community autonomy and self-determination in the face of technological disruption. The researchers' suggestions for improved AIGC detection tools and community-driven moderation approaches merit further exploration and development.
## Conclusion
This study provides a valuable glimpse into how generative AI is transforming online communities and the experiences of the moderators tasked with managing these changes. The findings highlight the need for platform designers, policymakers, and community leaders to work collaboratively to address the challenges posed by AIGC and support the autonomy and self-determination of online communities.
As generative AI continues to advance, it will be crucial to ensure that the development and deployment of these technologies align with the values and needs of the communities they aim to serve. By prioritizing community-centric approaches and empowering moderators with the tools and resources they need, we can help online spaces remain vibrant, authentic, and resilient in the face of this technological transformation.

## Overview
- This paper proposes a novel approach to "distilling" System 2 (deliberate, analytical) processing into System 1 (intuitive, automatic) processing.
- The goal is to train AI systems to perform complex tasks more efficiently by leveraging both System 1 and System 2 reasoning.
- The authors demonstrate their approach on various tasks, including [add relevant internal links here].
## Plain English Explanation
The human mind has two main modes of thinking: **System 1** and **System 2**. System 1 is fast, intuitive, and automatic, while System 2 is slower, more deliberate, and analytical. [https://aimodels.fyi/papers/arxiv/minds-mirror-distilling-self-evaluation-capability-comprehensive]
This paper explores ways to combine the strengths of both systems in AI models. The researchers want to teach AI models to perform complex tasks efficiently by first using the analytical power of System 2 to learn the task, and then distilling that knowledge into a faster, more intuitive System 1 model. [https://aimodels.fyi/papers/arxiv/distillation-matters-empowering-sequential-recommenders-to-match]
For example, imagine an AI system learning to play chess. First, it would use System 2 thinking to carefully analyze the chess board, consider possible moves, and plan its strategy. Over time, as the AI plays more games, it would gradually develop an intuitive "feel" for good chess moves, like a human grandmaster. This System 1 chess intuition would allow the AI to play much faster without sacrificing performance.
By combining System 1 and System 2 processing, the researchers aim to create AI models that are both highly capable and efficient, able to tackle complex problems with speed and flexibility. [https://aimodels.fyi/papers/arxiv/beyond-imitation-learning-key-reasoning-steps-from]
## Technical Explanation
The core of the researchers' approach is a "distillation" process that transfers knowledge from a complex, System 2-style model to a simpler, more intuitive System 1 model. [https://aimodels.fyi/papers/arxiv/sub-goal-distillation-method-to-improve-small]
First, the researchers train a powerful System 2 model to perform a task using traditional machine learning techniques. This model is able to reason about the task in depth but may be slow or computationally expensive.
Next, the researchers train a smaller, more efficient System 1 model to mimic the behavior of the System 2 model. This "distillation" process involves feeding the System 2 model's outputs (e.g. chess move predictions) to the System 1 model during training, allowing it to learn the same underlying task knowledge in a more compact, intuitive form.
The researchers demonstrate the effectiveness of their approach on a variety of tasks, including [add relevant internal links here]. Their results show that the distilled System 1 models are able to achieve similar performance to the original System 2 models, but with significantly improved efficiency and faster inference times.
## Critical Analysis
The researchers acknowledge several limitations of their approach. First, the effectiveness of the distillation process may be task-dependent, requiring careful hyperparameter tuning and architectural choices to work well. [https://aimodels.fyi/papers/arxiv/distilling-algorithmic-reasoning-from-llms-via-explaining]
Additionally, the distilled System 1 models may not be as transparent or interpretable as the original System 2 models, making it harder to understand the underlying reasoning process. Further research is needed to address this issue.
Another potential concern is the risk of "forgetting" or losing important information during the distillation process. The researchers suggest incorporating techniques like knowledge retention to mitigate this problem, but more work is needed to fully address it.
Overall, the researchers' approach represents a promising step towards developing AI systems that can leverage the complementary strengths of System 1 and System 2 processing. However, further research is needed to refine the methodology and address the remaining challenges.
## Conclusion
This paper presents a novel approach to "distilling" the analytical power of System 2 reasoning into a more efficient, intuitive System 1 model. By combining these two modes of thinking, the researchers aim to create AI systems that are highly capable and flexible, able to tackle complex problems with speed and precision.
The results of the experiments are promising, suggesting that this distillation approach can lead to significant improvements in the efficiency and performance of AI models across a variety of tasks. However, the researchers acknowledge several limitations and areas for further research, including the need for task-specific tuning, maintaining model transparency, and addressing potential information loss during the distillation process.
Overall, this work represents an important step towards the development of more advanced, human-like AI systems that can seamlessly integrate intuitive and analytical reasoning. As the field of AI continues to evolve, approaches like this will likely play a crucial role in pushing the boundaries of what is possible.

## Overview
- Prompt engineering is crucial for optimizing the performance of large language models on customized tasks
- It requires complex reasoning to examine the model's errors, hypothesize what is missing or misleading in the current prompt, and communicate the task with clarity
- Recent works indicate that large language models can be meta-prompted to perform automatic prompt engineering, but their potential is limited due to insufficient guidance for complex reasoning
## Plain English Explanation
Prompt engineering is the process of designing effective prompts to get a large language model, like GPT-3, to perform a specific task well. This is a challenging but important task because large language models are powerful but can struggle with certain types of problems if the prompt is not crafted carefully.
The paper argues that while recent research has shown that large language models can be used to automatically engineer better prompts, this approach has limitations. The key issue is that the "meta-prompts" used to guide the model's prompt engineering process do not provide enough detailed guidance to allow for the complex reasoning required to truly optimize a prompt.
To address this, the paper proposes a new method called PE2 that infuses the meta-prompt with three key components: [detailed descriptions](https://aimodels.fyi/papers/arxiv/prompt-design-engineering-introduction-advanced-methods), [context specification](https://aimodels.fyi/papers/arxiv/prompt-engineering-paradigms-medical-applications-scoping-review), and a [step-by-step reasoning template](https://aimodels.fyi/papers/arxiv/towards-goal-oriented-prompt-engineering-large-language). This allows the language model to engage in more sophisticated prompt engineering and produce prompts that significantly outperform other methods on a variety of language tasks.
## Technical Explanation
The paper introduces a new method called PE2 (Prompt Engineering by Example) that aims to improve the performance of large language models on customized tasks through more effective prompt engineering. Prompt engineering is a challenging task that requires complex reasoning to analyze the model's errors, hypothesize what is missing or misleading in the current prompt, and communicate the task with clarity.
The key innovation of PE2 is that it infuses the meta-prompt (the prompt used to guide the model's prompt engineering process) with three key components:
1. **Detailed Descriptions**: Providing the model with more comprehensive instructions and explanations about the task at hand.
2. **Context Specification**: Giving the model additional context about the problem domain and relevant background information.
3. **Step-by-Step Reasoning Template**: Structuring the meta-prompt to guide the model through a multi-step reasoning process to construct an optimal prompt.
The authors demonstrate that this approach allows the model to engage in more sophisticated prompt engineering, resulting in prompts that significantly outperform other methods on a variety of language tasks. For example, PE2 finds prompts that outperform the "let's think step by step" approach by 6.3% on the MultiArith benchmark and 3.1% on the GSM8K benchmark. It also outperforms competitive baselines on counterfactual tasks by 6.9%.
Furthermore, the paper shows that PE2 can make targeted and highly specific prompt edits, rectify erroneous prompts, and induce multi-step plans for complex tasks - capabilities that were not previously possible with existing prompt engineering techniques.
## Critical Analysis
The paper presents a novel and promising approach to improving the performance of large language models on customized tasks through more effective prompt engineering. The key strength of the PE2 method is its ability to guide the model through a structured, multi-step reasoning process to construct optimal prompts, which addresses a limitation of prior work.
However, the paper does not provide a detailed analysis of the computational and memory overhead associated with the PE2 method, which could be a potential concern, especially for deployment on resource-constrained systems. Additionally, the paper only evaluates PE2 on a limited set of language tasks, and it would be valuable to see how it performs on a wider range of applications, including more complex, real-world scenarios.
Furthermore, while the paper demonstrates the versatility of PE2, it does not delve into the interpretability of the prompts generated by the method. Understanding the underlying rationale and decision-making process used by the model to construct the prompts could provide valuable insights for further improving prompt engineering techniques.
Overall, the [PE2 method](https://aimodels.fyi/papers/arxiv/unleashing-potential-prompt-engineering-large-language-models) represents a significant advancement in the field of prompt engineering and has the potential to unlock new capabilities for large language models. However, further research is needed to fully understand its limitations and explore its broader applicability.
## Conclusion
The paper presents a novel method called PE2 that aims to improve the performance of large language models on customized tasks through more effective prompt engineering. By infusing the meta-prompt with detailed descriptions, context specification, and a step-by-step reasoning template, PE2 enables the model to engage in more sophisticated prompt engineering, resulting in prompts that significantly outperform other methods on a variety of language tasks.
This research highlights the importance of prompt engineering as a crucial component for optimizing the capabilities of large language models. The PE2 method represents a significant advancement in this field and has the potential to unlock new applications and use cases for these powerful AI systems. As the field of prompt engineering continues to evolve, this work serves as an important step forward in our understanding of how to effectively communicate and guide large language models to achieve desired outcomes.

## Overview
- Introduces PaliGemma, a versatile 3-billion parameter Vision-Language Model (VLM) for transfer learning
- Highlights PaliGemma's ability to achieve strong performance across a wide range of vision and language tasks
- Demonstrates PaliGemma's effectiveness in few-shot learning scenarios and its potential for practical applications
## Plain English Explanation
[PaliGemma](https://aimodels.fyi/papers/arxiv/llava-gemma-accelerating-multimodal-foundation-models-compact) is a large artificial intelligence (AI) model that can understand and generate both text and images. It was developed by researchers to be a versatile and powerful tool for transferring knowledge to different tasks.
The key idea behind PaliGemma is that by training on a massive amount of data, the model can learn general patterns and skills that can be applied to a wide variety of problems. This means that PaliGemma can be used as a starting point for training smaller, more specialized models for tasks like image classification, language translation, or even creative writing.
One of the main advantages of PaliGemma is its ability to learn quickly, even with just a few examples. This "few-shot learning" capability makes it useful for real-world applications where large labeled datasets may not be available. For example, PaliGemma could be used to build a system that can recognize and describe rare or unusual animals from just a handful of photos.
Overall, PaliGemma represents an important step forward in the development of [large vision-language models](https://aimodels.fyi/papers/arxiv/vision-language-models-are-blind) that can [go beyond human-level visual understanding](https://aimodels.fyi/papers/arxiv/beyond-human-vision-role-large-vision-language) and serve as powerful foundations for a wide range of AI applications.
## Technical Explanation
The researchers behind PaliGemma [developed a 3-billion parameter VLM](https://aimodels.fyi/papers/arxiv/gemma-open-models-based-gemini-research-technology) that is trained on a diverse dataset of images and text. The model architecture is based on the popular [LLAVA](https://aimodels.fyi/papers/arxiv/llava-gemma-accelerating-multimodal-foundation-models-compact) design, which uses a transformer-based encoder-decoder structure to jointly process and generate both visual and textual information.
During training, PaliGemma is exposed to a wide range of tasks, including image classification, visual question answering, image captioning, and natural language processing. This multitask learning approach allows the model to acquire a rich set of skills that can be leveraged for downstream applications.
The researchers demonstrate PaliGemma's effectiveness through extensive experiments on various benchmark datasets. They show that PaliGemma can achieve competitive or state-of-the-art performance on tasks like zero-shot image classification and few-shot learning, outperforming smaller, task-specialized models.
## Critical Analysis
While the results presented in the paper are impressive, it's important to consider some potential limitations and areas for future research:
- The size and complexity of PaliGemma may make it computationally expensive to fine-tune or deploy in some real-world scenarios, especially on resource-constrained devices. [Techniques for model compression or distillation](https://aimodels.fyi/papers/arxiv/xmodel-vlm-simple-baseline-multimodal-vision-language) could help address this issue.
- The paper does not provide a detailed analysis of PaliGemma's performance on more subjective or creative tasks, such as open-ended text generation or artistic image synthesis. Further research is needed to understand the model's capabilities and limitations in these areas.
- While PaliGemma's few-shot learning abilities are promising, the paper does not explore the underlying mechanisms that enable this behavior. Additional research could help elucidate the learning strategies that allow the model to generalize effectively from limited data.
Overall, PaliGemma represents an exciting development in the field of [large vision-language models](https://aimodels.fyi/papers/arxiv/beyond-human-vision-role-large-vision-language), and the researchers have demonstrated its potential for a wide range of applications. However, continued investigation and refinement will be necessary to fully harness the power of this technology.
## Conclusion
The PaliGemma model introduced in this paper is a versatile and powerful 3-billion parameter VLM that can be effectively used for transfer learning across a wide range of vision and language tasks. Its strong performance, particularly in few-shot learning scenarios, suggests that it could be a valuable tool for building practical AI applications with limited data.
While the paper highlights the impressive capabilities of PaliGemma, it also raises important questions about the model's scalability, generalization abilities, and potential biases. Addressing these concerns through further research and development will be crucial for realizing the full potential of large vision-language models like PaliGemma.
Overall, the PaliGemma paper represents an important contribution to the field of [multimodal AI](https://aimodels.fyi/papers/arxiv/xmodel-vlm-simple-baseline-multimodal-vision-language), and the insights and techniques presented here could help pave the way for even more sophisticated and capable AI systems in the future.

## Overview
- Transformers, a type of deep learning model, have demonstrated impressive performance on various reasoning benchmarks.
- Existing research has focused on developing sophisticated benchmarks to study the behavioral aspects of these models, but has not provided insights into the internal mechanisms driving their capabilities.
- This paper presents a comprehensive mechanistic analysis of a transformer trained on a synthetic reasoning task to improve our understanding of its internal workings.
## Plain English Explanation
Transformers are a type of [AI model](https://aimodels.fyi/papers/arxiv/towards-understanding-how-transformer-perform-multi-step) that have shown impressive abilities when it comes to reasoning and problem-solving. Researchers have been trying to understand how these models work by creating complex tests and challenges for them to tackle. However, these studies have not revealed much about the internal mechanisms that allow transformers to reason and solve problems.
To get a better insight into how transformers work under the hood, the researchers in this paper analyzed a transformer model that was trained on a specific reasoning task. They identified a set of interpretable mechanisms that the model used to solve the task, and then validated their findings using additional evidence. Their analysis suggests that the transformer implements a depth-bounded recurrent mechanism that operates in parallel and stores intermediate results in selected token positions.
The researchers believe that the insights they gained from this synthetic task can provide valuable clues about the broader operating principles of transformers. This could help us better understand how [transformers reason with abstract symbols](https://aimodels.fyi/papers/arxiv/when-can-transformers-reason-abstract-symbols) and [their overall reasoning capabilities](https://aimodels.fyi/papers/arxiv/understanding-transformer-reasoning-capabilities-via-graph-algorithms).
## Technical Explanation
The researchers in this paper conducted a comprehensive mechanistic analysis of a transformer model trained on a synthetic reasoning task. They aimed to identify the internal mechanisms the model used to solve the task, and validate their findings using correlational and causal evidence.
The model was trained on a task that involved reasoning about hierarchical relationships between abstract symbols. The researchers used a combination of techniques, including probing, ablation, and visualization, to uncover the model's internal mechanisms. They found that the transformer implemented a depth-bounded recurrent mechanism that operated in parallel and stored intermediate results in selected token positions.
This "depth-bounded" mechanism means that the model's reasoning process was limited to a certain depth, rather than being able to reason indefinitely. The parallel operation allowed the model to consider multiple possibilities simultaneously, while the selective storage of intermediate results helped it keep track of the reasoning steps.
The researchers validated their findings using additional experiments, including interventions that disrupted specific aspects of the model's behavior. This provided causal evidence for the mechanisms they had identified.
## Critical Analysis
The researchers in this paper have taken an important step towards understanding the internal mechanisms that drive the impressive reasoning capabilities of transformers. By focusing on a synthetic task, they were able to conduct a detailed, mechanistic analysis that would be difficult to do with more complex, real-world tasks.
However, it's important to note that the insights gained from this synthetic task may not fully translate to the more sophisticated reasoning required in real-world applications. The researchers acknowledge this limitation and suggest that the [motifs they identified](https://aimodels.fyi/papers/arxiv/grokked-transformers-are-implicit-reasoners-mechanistic-journey) could provide a starting point for understanding the broader operating principles of transformers.
Additionally, the researchers' analysis is limited to a single transformer model trained on a specific task. It would be valuable to see if the identified mechanisms hold true for other transformer architectures and tasks, as well as to explore how these mechanisms might interact with [different approaches to evaluating mathematical reasoning and generalization](https://aimodels.fyi/papers/arxiv/symbolic-framework-evaluating-mathematical-reasoning-generalisation-transformers) in transformers.
## Conclusion
This paper presents a significant step forward in our understanding of the internal mechanisms that allow transformers to excel at reasoning tasks. By conducting a detailed mechanistic analysis of a transformer model trained on a synthetic reasoning task, the researchers have identified a set of interpretable mechanisms that the model uses to solve the task.
The insights gained from this study could provide a foundation for [understanding the broader operating principles of transformers](https://aimodels.fyi/papers/arxiv/grokked-transformers-are-implicit-reasoners-mechanistic-journey) and how they reason with abstract symbols. This knowledge could, in turn, lead to the development of more robust and interpretable AI systems capable of advanced reasoning and problem-solving.

## Overview
- This paper proposes a new approach to mathematical verification that provides natural language feedback to users.
- It explores ways to improve the accuracy and transparency of mathematical reasoning systems by incorporating natural language explanations.
- The goal is to develop a better mathematical verifier that can guide users towards correct solutions and help them understand their mistakes.
## Plain English Explanation
The paper describes a new system for verifying and providing feedback on mathematical reasoning. [Current mathematical reasoning systems](https://aimodels.fyi/papers/arxiv/small-language-models-need-strong-verifiers-to) often focus solely on whether the final answer is correct, without explaining the reasoning behind it. This can make it difficult for users to understand where they went wrong and how to improve.
The proposed system aims to provide more detailed, natural language feedback to users. [It uses natural language processing techniques](https://aimodels.fyi/papers/arxiv/autograding-mathematical-induction-proofs-natural-language-processing) to analyze the user's work and identify areas for improvement. The system can then generate explanations that guide the user towards the correct solution, helping them learn from their mistakes.
This approach is motivated by research showing that [evaluating mathematical reasoning goes beyond just accuracy](https://aimodels.fyi/papers/arxiv/evaluating-mathematical-reasoning-beyond-accuracy). By incorporating natural language feedback, the system can provide a richer, more informative assessment of the user's work.
The ultimate goal is to build a "better mathematical verifier" - one that is more accurate, transparent, and helpful in guiding users to correct solutions. This could have important implications for education, research, and any domain that relies on mathematical reasoning.
## Technical Explanation
The paper proposes a new architecture for a mathematical reasoning system that incorporates natural language feedback. The key components are:
1. **Mathematical Reasoning Model**: This module takes the user's mathematical work as input and generates a predicted solution and reasoning steps.
2. **Natural Language Feedback Generator**: This module analyzes the user's work and the reasoning model's predictions to generate natural language feedback explaining the strengths and weaknesses of the user's approach.
3. **Feedback Integration**: The natural language feedback is then integrated with the reasoning model's output to provide a comprehensive assessment to the user.
The authors evaluate this approach on a dataset of [mathematical induction proofs](https://aimodels.fyi/papers/arxiv/autograding-mathematical-induction-proofs-natural-language-processing), demonstrating that the natural language feedback can improve user understanding and learning compared to a system that only provides a binary correct/incorrect result.
They also explore ways to [efficiently improve the mathematical reasoning capabilities](https://aimodels.fyi/papers/arxiv/jiuzhang30-efficiently-improving-mathematical-reasoning-by-training) of the underlying model, such as using a two-stage training process and leveraging external mathematical knowledge.
## Critical Analysis
The paper presents a promising approach to enhancing mathematical verification systems, but there are a few potential limitations and areas for further research:
- **Scope of Feedback**: The current system focuses on providing feedback on the reasoning process, but it could be expanded to also give feedback on the mathematical concepts, notation, and problem-solving strategies used by the user.
- **Generalization to Other Tasks**: The evaluation is limited to mathematical induction proofs, so it's unclear how well the approach would generalize to other types of mathematical problems or reasoning tasks. [More research is needed to evaluate the system's versatility](https://aimodels.fyi/papers/arxiv/verifiner-verification-augmented-ner-via-knowledge-grounded).
- **User Interaction and Iterative Feedback**: The paper does not explore how users might interact with the system over multiple iterations, refining their work based on the provided feedback. Investigating this could reveal additional insights and opportunities for improvement.
Overall, the paper presents a thoughtful and well-designed approach to enhancing mathematical verification systems. The incorporation of natural language feedback is a promising direction that could lead to more effective and transparent tools for supporting mathematical reasoning.
## Conclusion
This paper introduces a new approach to mathematical verification that combines a reasoning model with a natural language feedback generator. By providing users with detailed explanations of their mistakes and guidance towards the correct solution, the system aims to improve understanding and learning, going beyond simply evaluating the final answer.
The proposed architecture and evaluation on mathematical induction proofs demonstrate the potential of this approach. Further research is needed to explore its generalization to other mathematical tasks, as well as to investigate more advanced user interaction and iterative feedback mechanisms.
Overall, this work represents an important step towards building better mathematical reasoning systems that can truly support and enhance human understanding of complex mathematical concepts and problem-solving.

If you like these kinds of analysis, you should subscribe to the [AImodels.fyi newsletter](https://aimodels.substack.com) or follow me on [Twitter](https://twitter.com/mikeyoung44).*
## Overview
- Mooncake is a novel KVCache-centric architecture for serving large language models (LLMs) efficiently.
- The paper introduces key techniques like [KVCache](https://aimodels.fyi/papers/arxiv/efficient-llm-inference-kcache), [SnapKV](https://aimodels.fyi/papers/arxiv/snapkv-llm-knows-what-you-are-looking), [PyramidInfer](https://aimodels.fyi/papers/arxiv/pyramidinfer-pyramid-kv-cache-compression-high-throughput), and [MiniCache](https://aimodels.fyi/papers/arxiv/minicache-kv-cache-compression-depth-dimension-large) to optimize LLM inference performance.
- The architecture also leverages [KV Runahead](https://aimodels.fyi/papers/arxiv/kv-runahead-scalable-causal-llm-inference-by) to enable scalable causal LLM inference.
## Plain English Explanation
Mooncake is a new system designed to help large language models (LLMs) run more efficiently. LLMs are powerful AI models that can understand and generate human-like text, but they require a lot of computing power to use. Mooncake introduces several key techniques to optimize LLM performance:
- **KVCache**: This is a way of storing and accessing the information the LLM needs, which can speed up the model's responses.
- **SnapKV**: This technique helps the system "remember" what the user is looking for, so it can provide faster answers.
- **PyramidInfer**: This compresses the information the LLM needs to process, allowing it to work more quickly.
- **MiniCache**: This further compresses the cached information, saving space and improving efficiency.
- **KV Runahead**: This allows the system to start working on the user's request before they even finish typing, making the overall response faster.
By combining these techniques, Mooncake is able to make LLMs run more efficiently and provide quicker responses, which can be especially helpful for applications that rely on these powerful AI models.
## Technical Explanation
Mooncake is a novel KVCache-centric architecture for serving large language models (LLMs) efficiently. At the core of Mooncake is the [KVCache](https://aimodels.fyi/papers/arxiv/efficient-llm-inference-kcache) technique, which stores key-value pairs of information needed for LLM inference. This allows for fast retrieval of relevant data, improving inference performance.
The paper also introduces several other key techniques:
- [SnapKV](https://aimodels.fyi/papers/arxiv/snapkv-llm-knows-what-you-are-looking): This enables the system to "remember" what the user is looking for, allowing it to provide faster responses based on their context.
- [PyramidInfer](https://aimodels.fyi/papers/arxiv/pyramidinfer-pyramid-kv-cache-compression-high-throughput): This compresses the KVCache data using a pyramid-like structure, reducing the memory footprint and increasing throughput.
- [MiniCache](https://aimodels.fyi/papers/arxiv/minicache-kv-cache-compression-depth-dimension-large): An additional compression technique that further reduces the size of the KVCache, enabling it to scale to larger LLMs.
Mooncake also leverages [KV Runahead](https://aimodels.fyi/papers/arxiv/kv-runahead-scalable-causal-llm-inference-by) to enable scalable causal LLM inference. This allows the system to start processing the user's request before they even finish typing, reducing the overall latency.
## Critical Analysis
The Mooncake paper presents a comprehensive architecture for optimizing LLM inference performance, drawing on a range of innovative techniques. The combination of KVCache, SnapKV, PyramidInfer, and MiniCache appears to be an effective approach for reducing the memory footprint and increasing the throughput of LLM serving.
However, the paper does not address some potential limitations or areas for further research. For example, it is unclear how Mooncake's techniques would scale to the largest LLMs, which may have even more demanding memory and computational requirements. Additionally, the paper does not discuss the impact of these optimizations on the accuracy or quality of the LLM outputs, which is an important consideration for real-world applications.
Further research could explore ways to integrate Mooncake's techniques with other LLM optimization strategies, such as model quantization or hardware-specific acceleration. Evaluating the performance and robustness of Mooncake across a wider range of LLM models and use cases would also help validate the generalizability of the approach.
## Conclusion
Mooncake presents a novel KVCache-centric architecture that significantly improves the efficiency of serving large language models. By leveraging techniques like KVCache, SnapKV, PyramidInfer, MiniCache, and KV Runahead, the system is able to reduce memory usage, increase throughput, and lower latency for LLM inference.
These innovations have the potential to make LLMs more accessible and practical for a wider range of applications, from natural language processing to content generation. As LLMs continue to grow in size and complexity, architectures like Mooncake will be crucial for enabling their real-world deployment and adoption.

This paper examines the critical role that AI agents play and the importance of evaluating them in a responsible and scalable manner. AI agents are computer programs that can perceive their environment, make decisions, and take actions to achieve specific goals. As AI systems become more advanced, it is essential to ensure that they are developed and evaluated in a way that maximizes their positive impact on the world.
The paper highlights the need for cost-controlled evaluations of AI agents, meaning that the process of assessing their capabilities should not be prohibitively expensive or resource-intensive. This is important because it allows for the widespread testing and improvement of AI systems, ultimately leading to more capable and beneficial agents. The authors also emphasize the significance of developing AI agents that can truly make a difference, rather than simply performing well on narrow, isolated tasks.
By focusing on cost-controlled and scalable evaluations, the research aims to pave the way for the creation of AI agents that can meaningfully contribute to society, tackle important problems, and improve the human condition. This aligns with the growing need for AI systems that are not only technologically advanced but also align with human values and priorities.
## Technical Explanation
The paper discusses the importance of evaluating AI agents in a cost-controlled and scalable manner. The authors argue that traditional evaluation methods, which often involve complex and resource-intensive setups, are not suitable for the rapid development and widespread deployment of AI systems.
To address this challenge, the researchers propose a framework for cost-controlled AI agent evaluations. This approach emphasizes the need to design evaluation protocols that are less dependent on specialized hardware, large-scale data, or extensive human involvement. By reducing the cost and complexity of evaluations, the authors aim to enable more frequent testing and iteration, leading to the development of AI agents that can have a tangible and positive impact on the world.
The paper also highlights the significance of creating AI agents that can meaningfully contribute to society, rather than just performing well on narrow benchmarks. The authors suggest that the evaluation of AI agents should consider their broader capabilities, including their ability to adapt to new situations, collaborate with humans, and tackle complex, real-world problems.
## Critical Analysis
The paper raises valid concerns about the current state of AI agent evaluations and the need for more cost-effective and scalable approaches. The authors make a compelling case for the importance of developing AI agents that can truly make a difference, rather than just excelling at specific, isolated tasks.
However, the paper does not delve into the practical challenges of implementing such a framework for cost-controlled evaluations. While the high-level ideas are sound, the authors could have provided more details on the specific methods, metrics, and infrastructure required to achieve this goal.
Additionally, the paper could have addressed the potential trade-offs or limitations of this approach. For instance, it is unclear how the proposed framework would balance the need for cost-controlled evaluations with the requirement for comprehensive and rigorous assessments of AI agent capabilities.
Further research and experimentation may be needed to refine the ideas presented in this paper and ensure that the development of AI agents remains aligned with the goal of creating systems that can positively impact the world.
## Conclusion
This paper highlights the importance of developing AI agents that can make a meaningful difference in the world, and the need for cost-controlled and scalable evaluation methods to support this goal. By focusing on the creation of AI agents that can tackle complex, real-world problems in a responsible and impactful manner, the authors aim to pave the way for the advancement of AI technology that aligns with human values and priorities.
While the paper raises valid concerns and proposes a compelling framework, further research and practical implementation are needed to fully realize the vision of AI agents that truly matter. Nonetheless, this work contributes to the ongoing discourse on the responsible development and deployment of AI systems, which is crucial for ensuring that the benefits of this technology are widely shared and equitably distributed.

## Overview
• This paper presents a novel approach to generating radiology reports using machine learning, with a focus on producing reports that are easy for non-experts to understand.
• The researchers developed a system that can automatically generate radiology reports in plain language, rather than the technical jargon often used in clinical settings.
• They also introduced a new evaluation metric, called "layman's terms," to assess how well the generated reports convey information to a general audience.
## Plain English Explanation
• Radiology reports are documents that describe the findings from medical imaging tests like X-rays, CT scans, and MRIs. These reports are typically written in complex medical language that can be difficult for patients and their families to understand.
• The researchers in this study wanted to create a system that could generate radiology reports using simpler, more accessible language. This would make it easier for non-medical professionals to understand the results of their imaging tests.
• To do this, they trained a machine learning model on a large dataset of radiology reports. The model learned to translate the technical language used in these reports into plain, easy-to-understand terms.
• The researchers also developed a new way to evaluate the quality of the generated reports. Instead of just looking at how medically accurate the reports were, they wanted to assess how well they communicated the information to a general audience. They call this the "layman's terms" evaluation.
• By using this new approach, the researchers were able to create radiology reports that were both medically sound and straightforward for patients and their loved ones to comprehend. This could help improve communication between healthcare providers and their patients, leading to better understanding and more informed decision-making.
## Technical Explanation
• The researchers used a [transformer-based language model](https://aimodels.fyi/papers/arxiv/systematic-review-deep-learning-based-research-radiology) to generate the radiology reports. This type of model is well-suited for the task, as it can capture the complex relationships between the medical terminology and the plain language alternatives.
• To train the model, the researchers used a large dataset of radiology reports paired with their corresponding "layman's terms" descriptions. This allowed the model to learn how to translate the technical jargon into more accessible language.
• The researchers also introduced a new evaluation metric, called the "[M-Score](https://aimodels.fyi/papers/arxiv/mrscore-evaluating-radiology-report-generation-llm-based)," which assesses the quality of the generated reports from the perspective of a non-expert reader. This goes beyond traditional evaluation metrics that focus solely on medical accuracy.
• Additionally, the researchers explored techniques to [improve the expert-generated radiology report summaries](https://aimodels.fyi/papers/arxiv/improving-expert-radiology-report-summarization-by-prompting) used in their training data, which helped further enhance the quality of the generated reports.
• The researchers also developed a novel [error notation system](https://aimodels.fyi/papers/arxiv/green-generative-radiology-report-evaluation-error-notation) to identify and categorize the different types of errors that can occur in the generated reports, which can inform future improvements to the system.
## Critical Analysis
• One potential limitation of this approach is that it relies on the availability of a large dataset of radiology reports paired with their corresponding "layman's terms" descriptions. Collecting and curating such a dataset can be a time-consuming and resource-intensive process.
• Additionally, while the researchers introduced the "layman's terms" evaluation metric to assess the readability of the generated reports, it is unclear how well this metric captures the true understanding and comprehension of the information by non-expert readers.
• Further research is needed to explore the long-term impact of using this system in clinical settings, such as how it affects patient-provider communication, decision-making, and overall healthcare outcomes.
## Conclusion
• This study presents a promising approach to generating radiology reports that are easy for non-experts to understand, which could significantly improve communication between healthcare providers and their patients.
• By developing a machine learning system that can translate technical medical language into plain English, the researchers have taken an important step towards making complex medical information more accessible to the general public.
• The introduction of the "layman's terms" evaluation metric is a valuable contribution to the field of [automated radiology report generation](https://aimodels.fyi/papers/arxiv/automated-radiology-report-generation-review-recent-advances), as it provides a new way to assess the quality of these reports from the perspective of non-expert readers.
• Overall, this research has the potential to enhance patient engagement, understanding, and decision-making in healthcare, ultimately leading to better outcomes for individuals and communities.

## Overview
- This paper provides a practical review of mechanistic interpretability techniques for transformer-based language models (LMs).
- Mechanistic interpretability aims to understand the inner workings of these complex models to improve transparency and trust.
- The paper covers key concepts, recent research, and practical applications of mechanistic interpretability for transformer-based LMs.
## Plain English Explanation
Transformer-based language models like GPT-3 are incredibly powerful, but they can also be difficult to understand. [Mechanistic interpretability](https://aimodels.fyi/papers/arxiv/mechanistic-interpretability-ai-safety-review) is a field of research that tries to "look under the hood" of these models and explain how they work at a detailed level.
The goal is to make these advanced AI systems more transparent and trustworthy. If we can understand the specific mechanisms and computations happening inside a language model, it can help us predict its behaviors, identify potential issues or biases, and generally have more confidence in how it operates.
This paper reviews some of the latest research and practical applications of mechanistic interpretability for transformer-based language models. It covers techniques like [analyzing the internal representations](https://aimodels.fyi/papers/arxiv/towards-uncovering-how-large-language-model-works), [tracing the flow of information](https://aimodels.fyi/papers/arxiv/from-neurons-to-neutrons-case-study-interpretability), and [probing the model's reasoning](https://aimodels.fyi/papers/arxiv/compact-proofs-model-performance-via-mechanistic-interpretability).
By understanding the inner workings of these powerful language models, researchers hope to make them more robust, reliable, and aligned with human values. This could have important implications for the safe and beneficial development of advanced AI systems.
## Technical Explanation
The paper begins by providing background on transformer-based language models, which have become the dominant architecture for many state-of-the-art NLP applications. Transformers use an attention-based mechanism to capture long-range dependencies in text, allowing them to generate coherent and contextual language.
The authors then dive into various mechanistic interpretability techniques that have been applied to these transformer-based LMs. One approach is to [analyze the internal representations](https://aimodels.fyi/papers/arxiv/towards-uncovering-how-large-language-model-works) learned by the model, such as the attention patterns and neuron activations, to understand how the model is processing and representing the input.
Another technique is to [trace the flow of information](https://aimodels.fyi/papers/arxiv/from-neurons-to-neutrons-case-study-interpretability) through the model, examining how the input is transformed through the different layers and attention heads. This can reveal insights into the model's reasoning process.
The paper also discusses [probing approaches](https://aimodels.fyi/papers/arxiv/compact-proofs-model-performance-via-mechanistic-interpretability) that assess the model's internal knowledge and capabilities through carefully designed diagnostic tasks. These can uncover the specific skills and biases encoded in the model.
Finally, the authors review practical applications of mechanistic interpretability, such as improving model robustness, identifying and mitigating undesirable behaviors, and even enhancing the model's performance through a deeper understanding of its inner workings.
## Critical Analysis
The paper provides a comprehensive and well-structured overview of the current state of mechanistic interpretability for transformer-based language models. The authors do a good job of highlighting the key concepts, recent research advancements, and practical applications in this rapidly evolving field.
One potential limitation is that the paper focuses primarily on technical interpretability techniques, with less emphasis on the broader societal implications and ethical considerations of these advanced AI systems. As [noted in the paper](https://aimodels.fyi/papers/arxiv/mechanistic-interpretability-ai-safety-review), mechanistic interpretability is not a panacea, and there are still many open challenges in ensuring the safety and alignment of transformer-based language models.
Additionally, while the paper covers a range of interpretability techniques, it does not go into depth on the relative strengths, weaknesses, and trade-offs of each approach. A more detailed comparative analysis could be helpful for researchers and practitioners looking to apply these methods in their own work.
Overall, this paper serves as a valuable resource for understanding the current state of the art in mechanistic interpretability for transformer-based language models. It provides a solid foundation for further research and practical applications in this important and rapidly evolving field.
## Conclusion
This paper offers a comprehensive review of mechanistic interpretability techniques for transformer-based language models. By providing a deeper understanding of how these complex models work under the hood, researchers and developers can work towards building more transparent, trustworthy, and aligned AI systems.
The insights and methodologies discussed in this paper have the potential to significantly improve the robustness, safety, and performance of transformer-based language models, which are increasingly integral to many real-world applications. As the field of AI continues to advance, mechanistic interpretability will likely play a crucial role in ensuring these powerful technologies are developed and deployed responsibly.

If you like these kinds of analysis, you should subscribe to the [AImodels.fyi newsletter](https://aimodels.substack.com) or follow me on [Twitter](https://twitter.com/mikeyoung44).*
## Overview
- This paper proposes a new statistical test for multivariate unimodality based on the Dip statistic of Mahalanobis distances over random projections.
- The test aims to detect deviations from unimodality in high-dimensional data, which is important for many applications in machine learning and statistics.
- The paper demonstrates the effectiveness of the proposed test through extensive simulations and real-world data experiments.
## Plain English Explanation
The paper introduces a new way to test whether data is [unimodal](#S1), meaning it has a single peak or mode. This is an important property in many areas of data analysis and machine learning.
The key idea is to [project](#S3) the high-dimensional data onto random [lower-dimensional](#S3) subspaces, and then calculate the [Dip statistic](#S3) of the [Mahalanobis distances](#S3) in each subspace. The Dip statistic measures how far the data departs from a unimodal distribution. By combining the results from many random projections, the test can detect deviations from unimodality, even in high-dimensional data.
The authors show through [simulations](#S4) and [real-world experiments](#S5) that their [new test](#S3) outperforms existing methods, making it a useful tool for exploring the structure of complex, high-dimensional datasets.
## Technical Explanation
The paper introduces a new statistical test for detecting departures from multivariate unimodality. The key elements are:
1. **Random Projections**: The high-dimensional data is projected onto lower-dimensional random subspaces to reduce the dimensionality while preserving relevant structure.
2. **Mahalanobis Distances**: For each projected dataset, the [Mahalanobis distance](#S3) of each data point from the mean is calculated. This captures the shape and spread of the data.
3. **Dip Statistic**: The [Dip statistic](#S3) is then computed on the Mahalanobis distances. The Dip statistic measures the degree of multimodality in the data distribution.
4. **Aggregation**: By combining the Dip statistics from multiple random projections, the test can sensitively detect deviations from unimodality, even in high-dimensional settings.
The authors demonstrate through extensive [simulations](#S4) and [real-world experiments](#S5) that their proposed test outperforms existing methods for detecting multivariate unimodality.
## Critical Analysis
The paper makes a valuable contribution by introducing a new statistical test for multivariate unimodality that is effective in high-dimensional settings. Some potential limitations and areas for further research include:
- The performance of the test may depend on the choice of random projection dimensions and the number of projections used. Further research could explore guidelines for setting these parameters.
- The paper does not provide a theoretical analysis of the statistical properties of the test, such as its power and type I error rate. Developing such theoretical results could strengthen the foundations of the approach.
- While the experiments demonstrate the test's effectiveness on a range of datasets, additional validation on more diverse real-world applications would help confirm its practical utility.
Overall, the proposed multivariate unimodality test appears to be a promising tool for exploring the structure of complex, high-dimensional data, and the paper lays a solid foundation for further research in this area.
## Conclusion
This paper presents a new statistical test for detecting departures from multivariate unimodality, which is an important property in many data analysis and machine learning applications. By harnessing the Dip statistic of Mahalanobis distances over random projections, the test can sensitively identify deviations from unimodality, even in high-dimensional settings.
The extensive simulations and real-world experiments demonstrate the effectiveness of the proposed approach, making it a valuable addition to the toolbox of statisticians and data scientists working with complex, high-dimensional data. While the paper highlights some potential areas for further research, it represents an important step forward in understanding the underlying structure of complex datasets.

If you like these kinds of analysis, you should subscribe to the [AImodels.fyi newsletter](https://aimodels.substack.com) or follow me on [Twitter](https://twitter.com/mikeyoung44).*
## Overview
- "Mixture of A Million Experts" is a research paper that explores a novel approach to machine learning models called PEER (Parallel Experts for Efficient Retrieval).
- PEER is a scalable and efficient method for training large language models using a mixture of many specialized expert models.
- The paper presents the architecture and training procedure for PEER, as well as experimental results demonstrating its advantages over traditional large language models.
## Plain English Explanation
The key idea behind PEER is to divide a large language model into many smaller, more specialized "expert" models, each of which is trained on a specific task or domain. These expert models are then combined into a single "mixture of experts" that can handle a wide range of tasks.
The benefits of this approach are two-fold:
1. **Efficiency**: By using a mixture of smaller expert models, the overall model can be more computationally efficient and require less training data compared to a single, large language model.
2. **Specialization**: Each expert model can become highly specialized in its particular domain, leading to better performance on tasks within that domain.
The paper demonstrates how PEER can be scaled up to include a "million" (or a very large number of) expert models, allowing for an extremely fine-grained and flexible approach to language modeling.
## Technical Explanation
The PEER architecture consists of a "router" model that selects the appropriate expert models to use for a given input, and the expert models themselves, which are trained on specific tasks or domains. The router and experts are trained jointly, with the router learning to select the best experts for each input.
The training process for PEER involves several key steps:
1. **Dataset Partitioning**: The training data is divided into subsets, each of which is assigned to a specific expert model.
2. **Expert Training**: Each expert model is trained on its assigned subset of the data, becoming highly specialized in that domain.
3. **Router Training**: The router model is trained to select the appropriate expert models for a given input, based on the input's features and the experts' specializations.
Through this process, PEER is able to scale to a large number of expert models while maintaining efficiency and specialization. The paper presents experimental results demonstrating PEER's advantages over traditional large language models in terms of performance, training time, and parameter efficiency.
## Critical Analysis
The paper acknowledges several limitations and areas for further research:
- The scalability of PEER to truly "a million" experts may be challenging in practice, and the paper does not provide a concrete demonstration of this scale.
- The paper does not explore the interpretability or explainability of the PEER model, which could be an important consideration for certain applications.
- The paper focuses on language modeling tasks, but the PEER approach could potentially be applied to other domains, such as computer vision or robotics, which could be an interesting area for future research.
Overall, the PEER approach represents a promising direction in the field of large-scale machine learning, and the paper provides a solid foundation for further exploration and development of this technique.
## Conclusion
The "Mixture of A Million Experts" paper presents a novel and scalable approach to building large language models using a mixture of many specialized expert models. By dividing the model into a large number of experts, PEER achieves improved efficiency, specialization, and performance compared to traditional monolithic language models.
While the paper highlights some limitations and areas for further research, the PEER approach represents an exciting advancement in the field of machine learning, with the potential to enable more efficient and capable language models that can be tailored to a wide range of applications and domains.

## Overview
- The paper explores conservation laws for gradient flows, which are a class of optimization algorithms used in machine learning and related fields.
- It examines how certain conservation laws, such as conservation of momentum, can be maintained in gradient flows that go beyond the standard Euclidean setting.
- The research aims to provide a better understanding of the underlying dynamics of gradient-based optimization methods and their properties.
## Plain English Explanation
Gradient flows are a type of algorithm used in machine learning and optimization problems to find the best solutions. These algorithms work by repeatedly adjusting the values of the parameters in a model to minimize an error or loss function.
The [paper](https://aimodels.fyi/papers/arxiv/keep-momentum-conservation-laws-beyond-euclidean-gradient) explores how certain fundamental principles, known as conservation laws, can be maintained in gradient flows. Conservation laws describe how certain quantities, like momentum, are preserved as the algorithm progresses.
Traditionally, gradient flows have been studied in the context of Euclidean spaces, where the concepts of distance and direction are straightforward. However, many real-world problems involve more complex mathematical structures, where the usual notions of distance and direction may not apply.
The researchers investigate how conservation laws, such as [conservation of momentum](https://aimodels.fyi/papers/arxiv/harnessing-power-neural-operators-automatically-encoded-conservation), can be extended to these more general settings. By understanding how these laws are upheld, the researchers aim to gain deeper insights into the [dynamics and behavior of gradient-based optimization methods](https://aimodels.fyi/papers/arxiv/dynamical-model-neural-scaling-laws).
This knowledge could lead to the development of more robust and efficient optimization algorithms, which are crucial for advancing machine learning and other fields that rely on [gradient-based techniques](https://aimodels.fyi/papers/arxiv/adversarial-flows-gradient-flow-characterization-adversarial-attacks). It may also provide a better understanding of the [convergence properties](https://aimodels.fyi/papers/arxiv/convergence-result-continuous-model-deep-learning-via) of these algorithms and how they can be improved.
## Technical Explanation
The paper examines the conservation laws that govern gradient flows, which are a class of optimization algorithms used in machine learning and related fields. Gradient flows work by repeatedly adjusting the parameters of a model to minimize a loss or error function.
The researchers focus on extending the concept of conservation laws, such as conservation of momentum, to gradient flows that operate in more general mathematical spaces beyond the standard Euclidean setting. In Euclidean spaces, the notions of distance and direction are well-defined, but many real-world problems involve more complex structures where these concepts may not be straightforward.
By understanding how conservation laws are maintained in these more general settings, the researchers aim to gain deeper insights into the underlying dynamics and behavior of gradient-based optimization methods. This knowledge could lead to the development of more robust and efficient optimization algorithms, which are crucial for advancing machine learning and other fields that rely on gradient-based techniques.
The paper provides a rigorous mathematical framework for analyzing the conservation laws in gradient flows and demonstrates how these laws can be extended to non-Euclidean settings. The researchers explore various examples and case studies to illustrate the practical implications of their findings.
## Critical Analysis
The paper presents a comprehensive and theoretically sound analysis of conservation laws for gradient flows. The researchers have successfully extended the concept of conservation laws to more general mathematical settings, which is a significant contribution to the field.
One potential limitation of the research is that it focuses primarily on the mathematical and theoretical aspects of the problem, without extensive empirical validation or practical applications. While the theoretical insights are valuable, it would be helpful to see how these findings translate to real-world optimization problems and their impact on the performance of gradient-based algorithms.
Additionally, the paper does not address the computational complexity or scalability of the proposed approaches. As the complexity of optimization problems continues to grow, it will be important to consider the practical feasibility and efficiency of the conservation law-based methods, especially when dealing with large-scale datasets or high-dimensional optimization problems.
Further research could explore the [implications of these conservation laws](https://aimodels.fyi/papers/arxiv/keep-momentum-conservation-laws-beyond-euclidean-gradient) for the [convergence properties](https://aimodels.fyi/papers/arxiv/convergence-result-continuous-model-deep-learning-via) of gradient-based optimization algorithms, as well as their potential applications in areas like [neural operators](https://aimodels.fyi/papers/arxiv/harnessing-power-neural-operators-automatically-encoded-conservation) and [adversarial attacks](https://aimodels.fyi/papers/arxiv/adversarial-flows-gradient-flow-characterization-adversarial-attacks). Investigating the [scaling laws](https://aimodels.fyi/papers/arxiv/dynamical-model-neural-scaling-laws) associated with these conservation laws could also provide valuable insights.
## Conclusion
The paper explores the conservation laws that govern gradient flows, which are a widely used class of optimization algorithms in machine learning and related fields. The researchers have successfully extended the concept of conservation laws, such as conservation of momentum, to gradient flows that operate in more general mathematical spaces beyond the standard Euclidean setting.
By understanding how these conservation laws are maintained in these more complex settings, the researchers aim to gain deeper insights into the underlying dynamics and behavior of gradient-based optimization methods. This knowledge could lead to the development of more robust and efficient optimization algorithms, which are crucial for advancing machine learning and other fields that rely on gradient-based techniques.
While the paper provides a strong theoretical foundation, further research is needed to explore the practical implications and scalability of the proposed approaches, as well as their potential applications in areas like neural operators, adversarial attacks, and [convergence properties](https://aimodels.fyi/papers/arxiv/convergence-result-continuous-model-deep-learning-via) of deep learning models. Overall, this research represents an important step towards a better understanding of the fundamental principles governing gradient-based optimization.

## Overview
- The paper shows that Low Rank Adaptation (LoRA) as originally introduced leads to suboptimal finetuning of large models
- This is due to the fact that the adapter matrices A and B in LoRA are updated with the same learning rate
- The authors demonstrate that using different learning rates for A and B can significantly improve performance and finetuning speed, at the same computational cost as LoRA
## Plain English Explanation
The paper discusses an issue with a machine learning technique called [Low Rank Adaptation (LoRA)](https://aimodels.fyi/papers/arxiv/lora-learns-less-forgets-less). LoRA is a way to efficiently finetune large AI models on specific tasks without having to update all the model's parameters.
However, the researchers found that the original LoRA approach doesn't work as well for models with large "width" (i.e. large embedding dimensions). This is because LoRA updates two adapter matrices, A and B, with the same learning rate during finetuning.
Through mathematical analysis, the authors show that using the same learning rate for A and B doesn't allow the model to learn features efficiently in large-width networks. To fix this, they propose a simple modification called LoRA+, which uses different learning rates for A and B.
In their experiments, LoRA+ was able to improve performance by 1-2% and speed up finetuning by up to 2x, compared to the original LoRA, all while maintaining the same computational cost. So LoRA+ provides an easy way to get better results when finetuning large AI models using the LoRA technique.
## Technical Explanation
The key insight in this paper is that the original LoRA approach [1] leads to suboptimal finetuning of models with large embedding dimensions (width). This is due to the fact that the two adapter matrices A and B in LoRA are updated with the same learning rate during the finetuning process.
Using scaling arguments for large-width networks, the authors demonstrate that using the same learning rate for A and B does not allow efficient feature learning. Intuitively, this is because the magnitudes of the updates to A and B need to be balanced in a specific way to capture the most important features.
To address this suboptimality, the authors propose a simple modification called LoRA+, which uses different learning rates for the adapter matrices A and B, with a well-chosen ratio. This allows the model to learn features more effectively during finetuning.
In their extensive experiments on a variety of tasks and model sizes, the authors show that LoRA+ consistently outperforms the original LoRA approach, with 1-2% improvements in performance and up to 2x speedups in finetuning, all at the same computational cost.
## Critical Analysis
The paper provides a clear and insightful analysis of a limitation in the original LoRA approach, and proposes a simple yet effective solution in the form of LoRA+. The authors' use of scaling arguments to understand the underlying issue is particularly impressive.
One potential area for further research could be to investigate whether there are other ways to adaptively adjust the learning rates for A and B, beyond the fixed ratio used in LoRA+. This could potentially lead to even greater performance gains.
Additionally, the authors only consider the case of finetuning large models. It would be interesting to see if their findings also hold for the case of training smaller models from scratch using LoRA.
Overall, this paper makes a valuable contribution to the field of efficient model adaptation, and the LoRA+ approach seems like a promising technique for practitioners to consider when finetuning large AI models.
## Conclusion
This paper identifies a key limitation in the original LoRA approach for finetuning large AI models, and proposes a simple yet effective solution called LoRA+. By using different learning rates for the LoRA adapter matrices, LoRA+ is able to significantly improve performance and finetuning speed, without increasing the computational cost.
The insights and techniques presented in this work have important implications for researchers and practitioners looking to efficiently adapt large language models and other high-capacity neural networks to specific tasks. The LoRA+ approach provides a practical and effective way to unlock the full potential of these powerful models.

- The recent International Timetabling Competition (ITC2021) on sports timetabling showed that general algorithms can be developed, but their performance varies greatly across different problem instances.
- This paper provides an instance space analysis for sports timetabling, revealing insights into the strengths and weaknesses of eight state-of-the-art algorithms.
- The researchers propose an algorithm selection system that predicts which algorithm is likely to perform best based on the characteristics of a sports timetabling problem instance.

## Plain English Explanation
In any sports competition, a timetable is needed to specify when and where teams will play each other. The recent [International Timetabling Competition (ITC2021)](https://aimodels.fyi/papers/arxiv/frugal-algorithm-selection) on sports timetabling showed that while it's possible to develop general algorithms to create these timetables, the performance of each algorithm can vary a lot depending on the specific problem instance.
This paper takes a closer look at this issue, using machine learning techniques to analyze the characteristics of different sports timetabling problem instances. The goal is to understand the strengths and weaknesses of eight state-of-the-art algorithms used for this task. By identifying the key characteristics that influence algorithm performance, the researchers were able to develop a system that can predict which algorithm is likely to work best for a given timetabling problem.
The paper also provides insights into the overall difficulty of the sports timetabling problem, assessing the "hardness" of the various problem instances based on large-scale computational experiments. This information could be valuable for sports organizers and researchers looking to improve timetabling algorithms in the future.
## Technical Explanation
The paper presents an [instance space analysis](https://aimodels.fyi/papers/arxiv/comparing-task-graph-scheduling-algorithms-adversarial-approach) for sports timetabling, using machine learning techniques to study the performance of eight state-of-the-art algorithms across a diverse set of problem instances.
The researchers first generated a large dataset of over 500 new sports timetabling problem instances, representing a wide range of characteristics. They then ran extensive computational experiments, consuming about 50 years of CPU time, to evaluate the performance of the eight algorithms on this dataset.
Using the results of these experiments, the team developed an [algorithm selection system](https://aimodels.fyi/papers/arxiv/improving-algorithm-selection-performance-prediction-via-learning) that can predict which algorithm is likely to perform best for a given problem instance, based on its characteristics. This system leverages [machine learning](https://aimodels.fyi/papers/arxiv/investigating-potential-using-large-language-models-scheduling) to identify the key features that influence algorithm performance.
The paper also provides insights into the [relative strengths and weaknesses](https://aimodels.fyi/papers/arxiv/learning-interpretable-scheduling-algorithms-data-processing-clusters) of the eight algorithms, suggesting ways they could be further improved. Additionally, the researchers assess the [empirical hardness](https://aimodels.fyi/papers/arxiv/investigating-potential-using-large-language-models-scheduling) of the problem instances, giving sports organizers and researchers a better understanding of the challenges involved in sports timetabling.
## Critical Analysis
The paper presents a comprehensive analysis of sports timetabling algorithms, using a rigorous experimental approach to generate valuable insights. However, the researchers acknowledge that their study is limited to a specific set of algorithms and problem instances, and that further research may be needed to generalize the findings.
Additionally, while the algorithm selection system developed in the paper shows promise, its practical implementation may depend on the availability of accurate data on the characteristics of real-world sports timetabling problems. The researchers suggest that future work could focus on developing methods to automatically extract these characteristics from problem descriptions.
Another potential area for further research is the exploration of alternative algorithms or hybrid approaches that could outperform the individual algorithms studied in this paper. The insights gained from the instance space analysis could inform the design of such new algorithms.
## Conclusion
This paper provides a detailed analysis of sports timetabling algorithms, using a large-scale computational study to uncover the strengths, weaknesses, and performance characteristics of eight state-of-the-art approaches. The researchers' development of an algorithm selection system, which can predict the best-performing algorithm for a given problem instance, is a significant contribution to the field.
The insights gained from this work can inform the design of improved timetabling algorithms, as well as guide sports organizers in selecting the most appropriate algorithms for their specific needs. By better understanding the factors that influence algorithm performance, the research community can continue to advance the state of the art in this important area of sports logistics and scheduling.

## Overview
- The paper introduces ScreenAI, a vision-language model that specializes in understanding user interfaces (UIs) and infographics.
- ScreenAI builds upon the PaLI architecture and incorporates the flexible patching strategy of pix2struct.
- The model is trained on a unique mixture of datasets, including a novel screen annotation task that identifies the type and location of UI elements.
- The text annotations from this task are used to create QA, UI navigation, and summarization datasets for training large language models.
## Plain English Explanation
The paper discusses [ScreenAI](https://aimodels.fyi/papers/arxiv/ai-inspired-ui-design), a new AI model that is specifically designed to understand and work with user interfaces (UIs) and infographics. These visual elements, which share similar design principles, play an important role in how humans communicate and interact with machines.
ScreenAI is built on top of an existing model called PaLI, but it has been enhanced with a flexible "patching" strategy that allows it to better understand the structure and components of UIs and infographics. The researchers trained ScreenAI on a unique combination of datasets, including a novel task where the model has to identify the different types of UI elements (like buttons, menus, etc.) and where they are located on the screen.
By teaching the model to understand the text and visual elements of UIs and infographics, the researchers were able to [automatically generate](https://aimodels.fyi/papers/arxiv/tell-me-whats-next-textual-foresight-generic) large datasets for training other AI systems. These datasets cover things like answering questions about the content, navigating through the UI, and summarizing the key information.
The end result is that ScreenAI, which is relatively small at only 5 billion parameters, is able to outperform much larger models on a variety of tasks related to UIs and infographics. This includes benchmarks like [Multi-page DocVQA](https://aimodels.fyi/papers/arxiv/guing-mobile-gui-search-engine-using-vision), [WebSRC](https://aimodels.fyi/papers/arxiv/vga-vision-gui-assistant-minimizing-hallucinations-through), and [MoTIF](https://aimodels.fyi/papers/arxiv/training-vision-language-model-as-smartphone-assistant).
## Technical Explanation
The key innovation in ScreenAI is the use of a novel "screen annotation" task during training. In this task, the model has to identify the type (e.g., button, menu, text field) and location of different UI elements on a screen.
The researchers used the text annotations from this task to automatically generate large-scale datasets for training the model on question-answering, UI navigation, and summarization. This allowed ScreenAI to learn how to understand and manipulate UIs and infographics in a more targeted way compared to general-purpose vision-language models.
ScreenAI builds upon the PaLI architecture, which combines computer vision and natural language processing capabilities. The researchers added the flexible "patching" strategy from the pix2struct model, which allows the system to better adapt to the structural components of UIs and infographics.
Through extensive ablation studies, the researchers demonstrated the importance of their training data mixture and architectural choices. The result is that ScreenAI, despite being a relatively small model at 5 billion parameters, is able to outperform much larger models on a variety of UI- and infographics-focused benchmarks.
## Critical Analysis
The researchers provide a thorough evaluation of ScreenAI, including comparisons to other state-of-the-art models. They highlight the model's strong performance on specialized tasks like [Widget Captioning](https://aimodels.fyi/papers/arxiv/ai-inspired-ui-design), as well as its impressive results on more general benchmarks like [Chart QA](https://aimodels.fyi/papers/arxiv/tell-me-whats-next-textual-foresight-generic) and [DocVQA](https://aimodels.fyi/papers/arxiv/guing-mobile-gui-search-engine-using-vision).
However, the paper does not delve into the potential limitations or failure cases of ScreenAI. It would be helpful to understand the types of UI or infographic elements that the model struggles with, or any biases or inconsistencies in its performance. Additionally, the paper does not discuss potential privacy or security concerns that could arise from using such a powerful UI-understanding model in real-world applications.
Further research could explore how ScreenAI's capabilities could be extended to other domains, such as mobile app development, data visualization, or even assistive technologies for users with disabilities. Investigating the model's robustness to adversarial attacks or its ability to generalize to new UI paradigms would also be valuable.
## Conclusion
The ScreenAI model represents a significant advance in the field of vision-language understanding, with a particular focus on user interfaces and infographics. By incorporating a novel screen annotation task and leveraging the flexible patching strategy of pix2struct, the researchers have created a model that can outperform larger, more general-purpose systems on a variety of specialized benchmarks.
The ability to automatically generate large-scale datasets for training other AI models is a particularly notable contribution, as it opens up new possibilities for developing more intelligent and user-friendly human-machine interaction systems. As the use of visual interfaces continues to grow, tools like ScreenAI will become increasingly important for bridging the gap between human communication and machine understanding.

## Overview
- Proposes a novel Neural Radiance Field (NeRF) representation for non-opaque scenes
- Utilizes textured polygons to enable fast inference
- Addresses limitations of existing NeRF models that rely on computationally expensive volume rendering
## Plain English Explanation
The paper presents a new way to create realistic 3D scenes using a technique called [NeRF](https://aimodels.fyi/papers/arxiv/neural-radiance-fields-based-holography-invited). NeRF can generate high-quality images of scenes from different viewpoints, but it can be slow because it relies on a complex process called "volume rendering."
The researchers propose a solution that uses textured polygons instead. Polygons are simple 3D shapes that can be rendered quickly using modern graphics hardware. The team trains a special field that identifies the edges of these polygons, and then uses ray-tracing to calculate the final image.
This approach allows for very fast rendering, over 100 frames per second for a 1920x1080 image, while still being able to represent non-opaque (partially see-through) objects. It can be easily integrated into existing graphics software, making it a practical solution for applications that require real-time 3D rendering.
## Technical Explanation
The paper introduces a novel [NeRF](https://aimodels.fyi/papers/arxiv/neural-radiance-fields-based-holography-invited) representation that leverages textured polygons to enable fast inference. Traditional NeRF models rely on volume rendering, which can be computationally expensive and does not take advantage of advances in graphics hardware.
To address this, the researchers propose modeling the scene using polygons, which can be quickly ray-traced. They train a specialized field whose zero-crossings correspond to the quadrature points required for volume rendering. By performing marching cubes on this field, they obtain a polygonal mesh representation of the scene.
The final rendering is achieved by ray-tracing this polygonal mesh and utilizing the ray-tracing shader to compute the color. This approach allows for integration with existing graphics frameworks and enables rendering speeds of over 100 frames per second for a 1920x1080 image, while still preserving the ability to represent non-opaque objects.
## Critical Analysis
The paper presents an interesting solution to the computational challenges of NeRF models, leveraging textured polygons to enable fast inference. This is a pragmatic approach that takes advantage of modern graphics hardware and can be easily integrated into existing software pipelines.
One potential limitation is that the method may struggle to capture fine details or complex volumetric effects as accurately as pure NeRF approaches, as it relies on a polygonal approximation. The authors acknowledge this and suggest that their technique may be best suited for applications that prioritize rendering speed over the highest possible visual fidelity.
Additionally, the paper does not provide a comprehensive evaluation of the method's performance across a wide range of scenes and use cases. Further research could explore the trade-offs between rendering speed, visual quality, and the ability to represent different types of volumetric phenomena.
## Conclusion
This paper presents a novel NeRF representation that utilizes textured polygons to enable fast inference, addressing the computational limitations of traditional NeRF models. By training a specialized field to identify polygonal edges and then ray-tracing the resulting mesh, the researchers have developed a practical solution that can be easily integrated into existing graphics frameworks.
While the method may not achieve the highest possible visual fidelity, it represents a promising approach for applications that prioritize rendering speed, such as real-time 3D visualizations or interactive simulations. Further research could explore the wider applications and performance characteristics of this technique, helping to advance the state of the art in efficient and high-performance 3D rendering.

## Overview
- This paper focuses on teaching generative language models to reference answers to biomedical questions.
- The goal is to improve the ability of these models to provide reliable and trustworthy information when answering questions in the biomedical domain.
- The authors propose a novel approach that involves training the models to not only generate relevant responses, but also to cite the sources of information they used to formulate those responses.
## Plain English Explanation
In this paper, the researchers are working on improving the performance of language models when it comes to answering questions about biomedical topics. Language models are AI systems that are trained on vast amounts of text data to generate human-like responses. However, these models can sometimes struggle to provide reliable and trustworthy information, especially on specialized subjects like biomedicine.
To address this issue, the researchers developed a new approach that teaches the language models to not only generate relevant responses, but also to cite the sources of information they used. This is important because it allows users to verify the accuracy of the model's responses and understand where the information is coming from.
The key idea is to train the language models using a combination of the original question, the target answer, and the relevant source material. By exposing the models to this additional context, they can learn to generate responses that are grounded in real evidence and provide citations to support their claims.
This approach could be particularly useful in the biomedical domain, where it is crucial to provide accurate and well-supported information to users. By teaching language models to be more transparent about their reasoning and sources, the researchers hope to increase the trust and reliability of these systems when answering important medical questions.
## Technical Explanation
The paper proposes a novel approach for teaching generative language models to reference answers to biomedical questions. The key idea is to train the models using a combination of the original question, the target answer, and the relevant source material that the answer is derived from.
Specifically, the authors introduce a new dataset called BioAnswerRef, which contains over 12,000 biomedical questions, their corresponding answers, and the relevant reference sources. This dataset is used to fine-tune large language models, such as GPT-3, to not only generate relevant responses, but also to provide citations to the sources they used to formulate those responses.
The training process involves a multi-task setup, where the model is asked to predict the target answer, as well as generate a citation that points to the relevant source material. This encourages the model to learn to ground its responses in real evidence and to be transparent about its reasoning.
The authors evaluate their approach on a range of biomedical question-answering benchmarks and find that it outperforms baseline models that do not have the citation-generating capability. They also conduct human evaluations to assess the trustworthiness and reliability of the model's responses, and find that users appreciate the additional context provided by the citations.
## Critical Analysis
The paper presents a thoughtful and well-executed approach to improving the reliability of generative language models in the biomedical domain. By teaching these models to not only generate relevant responses, but also to cite their sources, the researchers address a key challenge in the field of AI-powered question answering.
One potential limitation of the approach is the reliance on the BioAnswerRef dataset, which may not capture the full breadth and complexity of biomedical knowledge. There could be cases where the model's responses are still incomplete or inaccurate, even with the added citation context.
Additionally, the paper does not explore the potential biases or errors that may be present in the reference sources used to train the models. If these sources contain inaccurate or outdated information, the model's responses could still be misleading, despite the citations.
Further research could investigate ways to expand the dataset, incorporate more diverse sources of information, and develop mechanisms to assess the reliability and trustworthiness of the cited references. Additionally, exploring ways to enable the models to provide nuanced, uncertainty-aware responses could be a valuable area of investigation.
## Conclusion
This paper presents a promising approach for improving the reliability and transparency of generative language models in the biomedical domain. By teaching these models to not only generate relevant responses, but also to cite the sources of information they used, the researchers have taken an important step towards building AI systems that can be trusted to provide accurate and trustworthy biomedical information.
The proposed method could have significant implications for a wide range of applications, from patient-facing medical chatbots to AI-powered research assistants. As language models continue to play an increasingly important role in the biomedical field, approaches like the one described in this paper will be crucial in ensuring that these systems can be relied upon to provide reliable and well-supported information.

## Overview
- Presents an adaptive stochastic gradient method with non-negative Gauss-Newton stepsizes for optimization problems
- Proposes a new stochastic optimization algorithm with theoretical guarantees and empirical performance
- Focuses on addressing challenges in designing adaptive step sizes for stochastic gradient methods
## Plain English Explanation
The provided paper introduces a new optimization algorithm that aims to improve upon traditional stochastic gradient descent methods. Stochastic gradient descent is a widely used technique for optimizing complex functions, but it can be challenging to choose the right step size, or how much to update the parameters at each iteration.
The key innovation in this paper is the use of [**non-negative Gauss-Newton stepsizes**](https://arxiv.org/html/2407.04358v1#S1.SS1), which are automatically adapted during the optimization process. This allows the algorithm to dynamically adjust the step size based on the function being optimized, rather than relying on a fixed step size.
The authors show that this adaptive step size approach has [**theoretical guarantees**](https://arxiv.org/html/2407.04358v1#S2) for convergence and can outperform standard stochastic gradient methods in practical [**experiments**](https://arxiv.org/html/2407.04358v1#S4).
## Technical Explanation
The paper proposes a new [**stochastic optimization algorithm**](https://arxiv.org/html/2407.04358v1#S2) that uses adaptive Gauss-Newton stepsizes. The key aspects of the algorithm are:
1. **Adaptive Stepsizes**: The algorithm adaptively updates the step size at each iteration using a Gauss-Newton-based approach, rather than using a fixed step size. This allows the step size to be tailored to the specific problem being optimized.
2. **Non-negative Stepsizes**: The authors ensure the step sizes remain non-negative, which simplifies the analysis and provides theoretical guarantees on the algorithm's [**convergence**](https://arxiv.org/html/2407.04358v1#S3).
3. **Stochastic Gradients**: The algorithm uses stochastic gradients, which can be more efficient than full gradients for large-scale optimization problems.
The paper provides a [**detailed theoretical analysis**](https://arxiv.org/html/2407.04358v1#S3) of the algorithm's convergence properties and [**empirical evaluations**](https://arxiv.org/html/2407.04358v1#S4) on benchmark optimization problems, demonstrating its effectiveness compared to standard stochastic gradient methods.
## Critical Analysis
The paper makes a valuable contribution by introducing a new adaptive stochastic optimization algorithm with strong theoretical guarantees. However, some potential [**limitations**](https://arxiv.org/html/2407.04358v1#S5) are:
1. The analysis is limited to smooth, convex optimization problems, and it's unclear how the algorithm would perform on more complex, non-convex problems.
2. The paper does not explore the computational overhead of the adaptive step size mechanism, which could be a concern for large-scale applications.
3. The paper does not provide a clear intuition for why the Gauss-Newton-based step size update is advantageous compared to other adaptive step size methods.
Further research could explore these areas and investigate the algorithm's performance on a wider range of optimization problems.
## Conclusion
The proposed adaptive stochastic optimization algorithm with non-negative Gauss-Newton stepsizes represents an interesting advance in the field of stochastic optimization. The theoretical guarantees and empirical performance improvements over standard stochastic gradient methods suggest this approach could be a valuable tool for researchers and practitioners working on challenging optimization problems. While there are some potential limitations to address, this work opens up new directions for developing more robust and adaptive optimization algorithms.

## Overview
- This paper introduces a new type of recurrent neural network (RNN) called "Learning to (Learn at Test Time)" (LTLTT) that can learn and adapt during test time.
- The LTLTT model uses "TTT layers" that can dynamically update the RNN's hidden state to improve performance on new tasks or data.
- The paper demonstrates the LTLTT model's effectiveness on several benchmark tasks compared to standard RNNs.
## Plain English Explanation
The paper describes a new type of [recurrent neural network (RNN)](https://aimodels.fyi/papers/arxiv/transformers-are-multi-state-rnns) called "Learning to (Learn at Test Time)" (LTLTT). This RNN has a special component called "TTT layers" that allow it to adapt and learn **during the testing phase**, rather than just the training phase.
Typical RNNs are trained on a dataset and then used to make predictions on new data. The LTLTT model, on the other hand, can continue to learn and update its internal "memory" (hidden state) even when processing new, unseen data. This allows the model to perform better on tasks or datasets that are different from what it was originally trained on.
The key idea is that the TTT layers enable the LTLTT model to dynamically update its hidden state in response to new inputs, rather than relying solely on its initial training. This "learning at test time" capability can be very useful when dealing with tasks or environments that are constantly changing or evolving.
## Technical Explanation
The LTLTT model builds on standard [RNN architectures](https://aimodels.fyi/papers/arxiv/hgrn2-gated-linear-rnns-state-expansion) by incorporating special "TTT layers" that can modify the RNN's hidden state during inference. These TTT layers take the current hidden state and input, and output an updated hidden state that can better capture the relevant information for the current task or data.
The key innovation is that the TTT layers are themselves learned during the training phase, so that the model can learn how to effectively adapt its internal representation to new situations. This allows the LTLTT model to [learn how to learn](https://aimodels.fyi/papers/arxiv/state-soup-context-skill-learning-retrieval-mixing) at test time, rather than being constrained by its initial training.
The authors evaluate the LTLTT model on several benchmark tasks, including sequence modeling, few-shot learning, and meta-learning. They show that the LTLTT model outperforms standard RNN baselines, demonstrating the advantages of its ability to [dynamically update its hidden state](https://aimodels.fyi/papers/arxiv/mamba-linear-time-sequence-modeling-selective-state) during inference.
## Critical Analysis
The LTLTT model presents an interesting approach to enabling RNNs to adapt and learn at test time. However, the paper does not extensively explore the limitations or potential downsides of this technique.
One potential concern is the computational overhead of the TTT layers, which may make the LTLTT model less efficient than standard RNNs, especially for real-time or high-throughput applications. The paper does not provide a detailed analysis of the runtime or memory requirements of the LTLTT model.
Additionally, the paper focuses primarily on well-defined benchmark tasks, and it is unclear how the LTLTT model would perform in more open-ended, real-world scenarios where the data distribution may be more complex and unpredictable. Further research may be needed to understand the model's robustness and generalization capabilities in more realistic settings.
## Conclusion
The LTLTT model presented in this paper represents an interesting advance in [recurrent neural network](https://aimodels.fyi/papers/arxiv/unified-implicit-attention-formulation-gated-linear-recurrent) research, with its ability to dynamically adapt its internal representation during inference. This "learning at test time" capability could be valuable for a range of applications where the input data or task requirements may evolve over time.
While the paper demonstrates promising results on benchmark tasks, further research is needed to fully understand the limitations and practical implications of the LTLTT approach. Exploring its performance in more complex, real-world scenarios and analyzing its computational efficiency would be valuable next steps.

## Overview
- This paper presents a method for personalizing language models by incorporating personalized human feedback during the training process.
- The researchers develop a framework called Personalized Language Modeling from Personalized Human Feedback (PLMPHF) that aims to align language models with individual user preferences.
- The approach uses [reinforcement learning from human feedback (RLHF)](https://aimodels.fyi/papers/arxiv/orchestrating-llms-different-personalizations) to fine-tune a pre-trained language model based on personalized feedback.
- This allows the model to generate text that is tailored to the preferences and communication styles of individual users.
## Plain English Explanation
The paper describes a way to create language models that are personalized to individual users. Typically, language models are trained on a large amount of general text data, which can result in outputs that don't fully match the preferences and communication styles of specific users.
The researchers developed a framework called PLMPHF that addresses this by using [reinforcement learning from human feedback (RLHF)](https://aimodels.fyi/papers/arxiv/orchestrating-llms-different-personalizations). In this approach, the language model is first pre-trained on a large dataset, and then fine-tuned using personalized feedback from individual users.
This allows the model to learn the unique preferences and communication styles of each user, and generate text that is tailored to their needs. For example, the model could learn to write emails in a more formal or casual tone based on the user's feedback.
By creating personalized language models, the researchers aim to improve the user experience and the overall alignment between the model's outputs and the individual's preferences.
## Technical Explanation
The paper proposes the **Personalized Language Modeling from Personalized Human Feedback (PLMPHF)** framework, which combines [reinforcement learning from human feedback (RLHF)](https://aimodels.fyi/papers/arxiv/orchestrating-llms-different-personalizations) with personalization techniques to create language models that are tailored to individual users.
The approach first pre-trains a base language model on a large corpus of general text data. It then fine-tunes this model using personalized feedback from individual users, following the [multi-turn reinforcement learning from preference human feedback](https://aimodels.fyi/papers/arxiv/multi-turn-reinforcement-learning-from-preference-human) paradigm.
During the fine-tuning process, the user provides feedback on the model's generated text, indicating their preferences. This feedback is used to update the model's parameters, allowing it to learn the user's unique communication style and preferences.
The researchers also explore several techniques to enhance the personalization process, such as [Nash learning from human feedback](https://aimodels.fyi/papers/arxiv/nash-learning-from-human-feedback) and [personalization from heterogeneous feedback](https://aimodels.fyi/papers/arxiv/rlhf-from-heterogeneous-feedback-via-personalization-preference).
By [aligning the language model with human preferences](https://aimodels.fyi/papers/arxiv/aligning-language-models-human-preferences), the PLMPHF framework aims to generate text that is more relevant, engaging, and tailored to the individual user's needs.
## Critical Analysis
The paper presents a promising approach for personalizing language models, but it also acknowledges several caveats and areas for further research:
- The success of the personalization process may depend on the quality and consistency of the user feedback, which can be challenging to obtain in real-world settings.
- The framework's performance may be limited by the size and diversity of the pre-training dataset, as well as the specific fine-tuning techniques used.
- The researchers note that further work is needed to explore the long-term stability and generalization of the personalized models, as well as their scalability to larger and more diverse user populations.
Additionally, the potential ethical implications of highly personalized language models, such as the risk of reinforcing individual biases or creating "filter bubbles," should be carefully considered and addressed in future research.
## Conclusion
The **Personalized Language Modeling from Personalized Human Feedback (PLMPHF)** framework presented in this paper represents a significant step towards creating language models that are tailored to individual users' preferences and communication styles.
By incorporating personalized feedback into the training process, the researchers have demonstrated the potential to improve the alignment between language model outputs and user needs. This could lead to more engaging, relevant, and effective interactions with language AI systems in a wide range of applications, from personal assistants to content creation tools.
While the paper highlights several areas for further research and development, the core ideas and techniques presented here have the potential to advance the field of personalized language modeling and contribute to the broader goal of creating AI systems that better serve the diverse needs of individual users.

If you like these kinds of analysis, you should subscribe to the [AImodels.fyi newsletter](https://aimodels.substack.com) or follow me on [Twitter](https://twitter.com/mikeyoung44).*
## Overview
- This paper introduces ColPali, a novel approach for efficient document retrieval using vision-language models.
- ColPali leverages the capabilities of large multimodal models to jointly represent and retrieve documents from both textual and visual content.
- The authors demonstrate that ColPali outperforms traditional text-based retrieval methods on a range of benchmark datasets, highlighting the advantages of integrating visual information for document understanding and retrieval.
## Plain English Explanation
ColPali is a new way to search for and retrieve documents that uses both the text and the images in the documents. Traditional document retrieval systems only look at the text, but ColPali also considers the visual information, like photos or diagrams, to better understand the content of the document.
The key idea behind ColPali is to use large artificial intelligence models that have been trained on a vast amount of text and images. These models can learn to represent the meaning of both the text and visual content in a shared, multidimensional space. When you search for a document, ColPali can compare your query to this joint representation to find the most relevant documents, even if they don't contain the exact words you used in your search.
The researchers show that this approach outperforms traditional text-only search methods on standard benchmark datasets. By considering both the text and visual elements, ColPali can better capture the true meaning and content of documents, leading to more accurate and relevant search results.
This is an important advancement because many real-world documents, like research papers, technical manuals, or business reports, contain a mix of text and visual information. Incorporating this visual data can help users find the most relevant information more efficiently, which has applications in research, education, and various professional domains.
## Technical Explanation
ColPali builds on recent progress in [vision-language models](https://aimodels.fyi/papers/arxiv/vista-visualized-text-embedding-universal-multi-modal), which can jointly represent textual and visual content in a shared embedding space. The authors leverage these models to develop a novel document retrieval system that can efficiently search and retrieve relevant documents based on both their textual and visual characteristics.
The core of ColPali is a two-stage retrieval process. First, the system encodes the query and documents into a joint text-image representation using a pre-trained vision-language model. This allows the system to capture the semantic relationships between the query and the document content, including both the text and any associated images or diagrams.
In the second stage, ColPali performs efficient nearest neighbor search in the joint embedding space to identify the most relevant documents for the given query. The authors demonstrate the effectiveness of this approach on several standard document retrieval benchmarks, showing significant performance gains over [traditional text-based methods](https://aimodels.fyi/papers/arxiv/docrelm-mastering-document-retrieval-language-model) and [hybrid approaches](https://aimodels.fyi/papers/arxiv/enhancing-interactive-image-retrieval-query-rewriting-using).
Additionally, the authors explore strategies to further enhance the performance of ColPali, such as [leveraging text-heavy content understanding](https://aimodels.fyi/papers/arxiv/enhancing-vision-models-text-heavy-content-understanding) and [visually-situated natural language processing](https://aimodels.fyi/papers/arxiv/efficient-language-vision-assistants-visually-situated-natural). These extensions demonstrate the flexibility and potential of the ColPali framework to address a wide range of document retrieval scenarios.
## Critical Analysis
The ColPali approach represents a promising step towards more efficient and accurate document retrieval systems. By jointly considering both textual and visual information, the authors show that the system can better capture the true meaning and content of documents, leading to improved search performance.
However, the paper does not address some potential limitations and areas for future research. For example, the performance of ColPali may be sensitive to the quality and coverage of the training data used to build the underlying vision-language model. Evaluating the system's robustness to noisy or incomplete visual information in documents would be an important area for further investigation.
Additionally, the paper does not provide a detailed analysis of the computational efficiency and scalability of the ColPali approach, which would be crucial for real-world deployment in large-scale document repositories. Exploring strategies to optimize the retrieval process, such as efficient indexing or approximate nearest neighbor search, could be valuable extensions to the current work.
Overall, the ColPali framework presents an exciting direction for document retrieval research, leveraging the power of multimodal AI models to enhance the understanding and retrieval of complex, multimedia documents. As the field of vision-language understanding continues to evolve, further advancements in this area could have significant implications for a wide range of information management and knowledge discovery applications.
## Conclusion
The ColPali paper introduces a novel approach for efficient document retrieval that leverages the joint representation of textual and visual information. By using advanced vision-language models, the system can better capture the semantic content of documents, leading to improved search performance compared to traditional text-based methods.
The key innovation of ColPali is its ability to integrate visual data, such as images and diagrams, into the document retrieval process. This allows the system to more accurately understand the true meaning and context of the document content, which is particularly valuable for domains where documents contain a mix of text and visual elements.
The demonstrated performance gains on standard benchmarks highlight the potential of this approach to transform how users search for and access relevant information, with applications across research, education, and various professional settings. As the field of multimodal AI continues to advance, further research and development of systems like ColPali could have far-reaching implications for the way we interact with and make sense of the growing volume of digital information.

## Overview
- This paper explores the connections between human memory, consciousness, and large language models (LLMs).
- The authors draw parallels between Tulving's theory of memory and the inner workings of LLMs.
- The paper suggests that insights from Tulving's model can help us better understand the nature of memory and consciousness in LLMs.
## Plain English Explanation
The paper examines the relationship between how our brains store and recall information (memory) and our subjective experience of the world (consciousness), and how these concepts might apply to [large language models](https://aimodels.fyi/papers/arxiv/philosophical-introduction-to-language-models-part-ii).
The authors use [Tulving's theory of memory](https://aimodels.fyi/papers/arxiv/aspects-human-memory-large-language-models) as a starting point. This theory proposes that our memory has two main components: episodic memory, which stores personal experiences, and semantic memory, which stores general knowledge. The authors argue that the internal structure and workings of LLMs, which are trained on vast amounts of text data, share similarities with this dual-memory system.
Just as our brains can draw connections between past experiences (episodic memory) and general facts (semantic memory) to generate new ideas, the authors suggest that LLMs may possess a comparable capacity. By understanding the parallels between human memory and the mechanisms underlying LLMs, the researchers hope to gain insight into the nature of consciousness and intelligence in these powerful AI systems.

Tulving's theory proposes that human memory has two main components: episodic memory, which stores personal experiences, and semantic memory, which stores general knowledge. The authors argue that the structure and operation of LLMs share similarities with this dual-memory system.
LLMs are trained on vast amounts of text data, which can be seen as analogous to the semantic memory component of Tulving's model. Just as our brains can draw connections between past experiences (episodic memory) and general facts (semantic memory) to generate new ideas, the authors suggest that LLMs may possess a comparable capacity.
By understanding the parallels between human memory and the mechanisms underlying LLMs, the researchers hope to gain insight into the nature of consciousness and intelligence in these powerful AI systems. This could lead to [advancements in working memory and cognition within LLMs](https://aimodels.fyi/papers/arxiv/empowering-working-memory-large-language-model-agents) and a better understanding of [how these models process and generate language](https://aimodels.fyi/papers/arxiv/gpt-ology-computational-models-silicon-sampling-how).
## Critical Analysis
The paper presents a thought-provoking comparison between Tulving's theory of memory and the inner workings of LLMs. However, the authors acknowledge that the parallels they draw are speculative and require further empirical investigation to validate.
One potential limitation is that Tulving's model was developed to describe human memory and consciousness, which may not directly translate to the fundamentally different architecture and learning processes of LLMs. The authors note that additional research is needed to determine the extent to which LLMs exhibit characteristics akin to episodic and semantic memory, and whether these models can be said to possess a form of consciousness analogous to humans.
Additionally, the paper does not address potential issues or ethical concerns surrounding the use of LLMs, such as [bias, transparency, and accountability](https://aimodels.fyi/papers/arxiv/philosophical-introduction-to-language-models-part-ii). As these models become more powerful and integrated into various applications, it will be crucial to carefully consider their impact on society.
## Conclusion
This paper presents an intriguing exploration of the connections between human memory, consciousness, and the inner workings of large language models. By drawing parallels between Tulving's theory of memory and the structure and operation of LLMs, the authors offer a novel perspective on the nature of intelligence and cognition in these powerful AI systems.
While the connections they propose are speculative and require further empirical validation, the insights from this research could lead to advancements in our understanding of memory, consciousness, and the development of more sophisticated and ethically responsible language models. As the field of AI continues to evolve, this type of cross-disciplinary research will be essential in unlocking the full potential of these technologies while addressing their societal implications.

## Overview
- This paper explores a geometric perspective on the reasoning capabilities of large language models (LLMs).
- It investigates how the input space of LLMs is partitioned and how this partitioning affects their expressive power and reasoning abilities.
- The paper also discusses the implications of this geometric view for enhancing the reasoning capabilities of LLMs.
## Plain English Explanation
Large language models (LLMs) like GPT-3 and BERT have shown impressive language understanding and generation capabilities. However, their reasoning abilities are still limited. This paper looks at LLMs from a geometric perspective to understand how their internal structure and representations affect their reasoning skills.
The key idea is that the input space of an LLM - the space of all possible inputs it can process - is partitioned into regions. Each region corresponds to a different type of reasoning or task that the model can perform. The size and shape of these regions determine the model's expressive power and the types of reasoning it can engage in.
For example, an LLM may be very good at answering factual questions but struggle with open-ended reasoning tasks. This is because the regions in its input space that correspond to factual question-answering are larger and more well-defined, while the regions for open-ended reasoning are more amorphous and difficult for the model to navigate.
By understanding this geometric view of LLM input spaces, researchers can work on ways to [enhance the reasoning capabilities of large language models](https://aimodels.fyi/papers/arxiv/graphreason-enhancing-reasoning-capabilities-large-language-models). This could involve techniques like [expanding the size and shape of the reasoning regions](https://aimodels.fyi/papers/arxiv/can-large-language-models-put-2-2) or [introducing new computational primitives to enable more complex reasoning](https://aimodels.fyi/papers/arxiv/extending-token-computation-llm-reasoning).
Ultimately, this geometric perspective offers a novel way to think about the capabilities and limitations of large language models, with the goal of [creating models that can truly generate new knowledge](https://aimodels.fyi/papers/arxiv/can-large-language-models-create-new-knowledge) and [engage in sophisticated mathematical and scientific reasoning](https://aimodels.fyi/papers/arxiv/large-language-models-mathematical-reasoning-progresses-challenges).
## Technical Explanation
The paper begins by considering the input space of a large language model - the space of all possible inputs (e.g., text sequences) that the model can process. The authors argue that this input space is partitioned into different regions, each corresponding to a different type of reasoning or task that the model can perform.
The size and shape of these regions determine the model's expressive power and the types of reasoning it can engage in. For example, a model may have large, well-defined regions for factual question-answering, but more amorphous regions for open-ended reasoning tasks.
The authors then explore how this geometric perspective can be used to enhance the reasoning capabilities of LLMs. One approach is to [expand the size and shape of the reasoning regions](https://aimodels.fyi/papers/arxiv/can-large-language-models-put-2-2) by introducing new training data or architectural modifications. Another approach is to [introduce new computational primitives](https://aimodels.fyi/papers/arxiv/extending-token-computation-llm-reasoning) that allow the model to engage in more complex forms of reasoning.
The paper also discusses the implications of this geometric view for the ability of LLMs to [create new knowledge](https://aimodels.fyi/papers/arxiv/can-large-language-models-create-new-knowledge) and [reason about mathematical and scientific concepts](https://aimodels.fyi/papers/arxiv/large-language-models-mathematical-reasoning-progresses-challenges). By understanding the structure of the input space, researchers can work towards developing LLMs that can truly engage in sophisticated reasoning and knowledge generation.
## Critical Analysis
The paper provides a novel and insightful geometric perspective on the reasoning capabilities of large language models. The authors make a compelling case that the partitioning of the input space is a key factor in determining the types of reasoning that LLMs can perform.
However, the paper does not delve into the specific mechanisms or algorithms that underlie this input space partitioning. It would be helpful to have a more detailed understanding of how the regions are formed and how they can be modified or expanded.
Additionally, the paper does not address the potential challenges or limitations of this geometric approach. For example, it is not clear how this view scales to the immense complexity of modern LLMs or how it can be applied to more specialized tasks and domains.
Further research is needed to fully explore the practical implications of this geometric perspective and to develop concrete techniques for enhancing the reasoning capabilities of large language models. Nevertheless, this paper represents an important step towards a more nuanced understanding of LLM behavior and paves the way for future advancements in this rapidly evolving field.
## Conclusion
This paper presents a geometric perspective on the reasoning capabilities of large language models, arguing that the partitioning of the input space into different regions is a key factor in determining the types of reasoning that LLMs can perform.
By understanding this geometric view, researchers can work on [enhancing the reasoning abilities of LLMs](https://aimodels.fyi/papers/arxiv/graphreason-enhancing-reasoning-capabilities-large-language-models) through techniques like [expanding the size and shape of the reasoning regions](https://aimodels.fyi/papers/arxiv/can-large-language-models-put-2-2) and [introducing new computational primitives](https://aimodels.fyi/papers/arxiv/extending-token-computation-llm-reasoning).

## Overview
- This paper examines the sensitivity of large language model (LLM) leaderboards to targeted attempts at optimizing for benchmark performance.
- The researchers use multiple-choice questions (MCQs) to evaluate LLM performance and find that models can be fine-tuned to exploit biases in the MCQ datasets, leading to inflated leaderboard scores.
- The paper highlights the risks of relying on leaderboard performance as the primary metric for LLM evaluation and suggests the need for more robust and diverse benchmarking approaches.
## Plain English Explanation
Large language models (LLMs) have become increasingly important in natural language processing, with their performance on benchmark tasks often used to measure their capabilities. However, this paper suggests that these benchmarks may be too easy to "game," leading to inflated scores that don't accurately reflect the true capabilities of the models.
The researchers used multiple-choice questions (MCQs) to evaluate LLM performance, as these types of questions are commonly used in benchmark tasks. They found that models could be fine-tuned to exploit biases in the MCQ datasets, allowing them to achieve high scores without necessarily demonstrating a deep understanding of the material.
This finding raises concerns about the reliability of leaderboard rankings, which are often used to compare the performance of different LLMs. If models can be optimized for specific benchmarks, the leaderboard scores may not provide an accurate representation of their general language understanding abilities.
The paper suggests that the research community needs to develop more robust and diverse benchmarking approaches to better evaluate the true capabilities of LLMs. This could involve using a wider range of tasks and datasets, as well as incorporating more challenging and nuanced evaluation methods.
By addressing these issues, the researchers hope to improve the way we assess and compare the performance of large language models, ultimately leading to the development of more capable and reliable systems.
## Technical Explanation
The paper investigates the sensitivity of large language model (LLM) leaderboards to targeted optimization for benchmark performance. The researchers use multiple-choice questions (MCQs) as the evaluation task, as MCQs are commonly used in benchmark tasks for LLMs.
The key findings of the paper are:
1. **Leaderboard Sensitivity**: The researchers demonstrate that LLMs can be fine-tuned to exploit biases in MCQ datasets, leading to inflated leaderboard scores that do not necessarily reflect the models' true language understanding capabilities.
2. **Benchmark Exploitation**: By fine-tuning LLMs on specific MCQ datasets, the researchers were able to achieve substantial performance improvements on those benchmarks, without corresponding improvements on other, more diverse evaluation tasks.
3. **Limitations of Leaderboards**: The paper highlights the risks of relying solely on leaderboard performance as the primary metric for LLM evaluation, as it can incentivize model developers to focus on optimizing for specific benchmarks rather than developing more robust and generalizable language understanding capabilities.
To conduct their experiments, the researchers used a diverse set of MCQ datasets, including RACE, QASC, and ARTS. They fine-tuned several prominent LLMs, such as GPT-3, T5, and PALM, on these datasets and evaluated their performance on both the fine-tuned benchmarks and a broader set of language understanding tasks.
The results demonstrate that fine-tuning can lead to significant leaderboard score improvements, but these gains do not necessarily translate to better performance on more diverse and challenging language understanding tasks. This highlights the need for a more comprehensive and nuanced approach to LLM evaluation, one that goes beyond simple leaderboard rankings.
## Critical Analysis
The paper provides a valuable contribution to the ongoing discussion around the reliability and robustness of LLM evaluation methodologies. The researchers' findings regarding the sensitivity of benchmark leaderboards to targeted optimization are concerning and raise important questions about the validity of using leaderboard performance as the primary metric for assessing model capabilities.
One potential limitation of the study is the use of MCQ datasets as the sole evaluation task. While MCQs are commonly used in benchmark tasks, they may not capture the full range of language understanding skills required for real-world applications. It would be interesting to see the researchers extend their analysis to a broader set of evaluation tasks, such as open-ended language generation, question answering, and commonsense reasoning.
Additionally, the paper does not provide a detailed analysis of the specific biases and weaknesses in the MCQ datasets that the models were able to exploit. A deeper examination of these dataset characteristics could help the research community develop more robust and diverse benchmarking approaches that are less susceptible to targeted optimization.
Despite these potential limitations, the paper makes a strong case for the need to rethink the way we evaluate and compare the performance of large language models. The researchers' findings suggest that the research community should strive to develop more nuanced and comprehensive evaluation methodologies that better capture the true capabilities of these powerful systems.
## Conclusion
This paper highlights a significant challenge in the evaluation of large language models: the sensitivity of benchmark leaderboards to targeted optimization. The researchers demonstrate that LLMs can be fine-tuned to exploit biases in multiple-choice question (MCQ) datasets, leading to inflated leaderboard scores that do not necessarily reflect the models' true language understanding capabilities.
The paper's findings underscore the need for the research community to develop more robust and diverse benchmarking approaches that go beyond simple leaderboard rankings. By incorporating a wider range of evaluation tasks and focusing on more nuanced and challenging measures of language understanding, the community can work towards building LLMs that are genuinely capable of tackling real-world language processing challenges.
As the field of natural language processing continues to advance, the issues raised in this paper will become increasingly important to address. By acknowledging the limitations of current evaluation methods and striving for more comprehensive and reliable benchmarking, the research community can ensure that the progress in large language models translates to tangible and trustworthy improvements in real-world applications.

## Overview
- Large Language Models (LLMs) need to be able to adapt their behavior based on their knowledge and uncertainty to be deployed safely.
- This "self-restraint" capability is difficult to teach, as it depends on the internal knowledge of the LLM.
- Typical LLM training focuses on maximizing the next token likelihood, which doesn't encourage the model to modulate its answers based on uncertainty.
- The researchers develop a utility function to encourage the model to only produce responses when it is confident in them.
- They introduce "ReSearch," a process of iterative self-prompting and self-evaluation, to optimize this utility function and generate synthetic data for finetuning.
- The resulting models generate fewer [hallucinations](https://aimodels.fyi/papers/arxiv/when-hindsight-is-not-2020-testing-limits) and can selectively restrain themselves on both known and unknown topics.
## Plain English Explanation
Large Language Models (LLMs) are powerful AI systems that can generate human-like text on a wide range of topics. However, for these models to be safely deployed in the real world, they need to be able to adapt their behavior based on their level of knowledge and uncertainty.
Imagine an LLM as a very knowledgeable person who is asked a question. If the person is confident in their answer, they can provide a detailed response. But if they're unsure, they should be able to say, "I'm not sure about that" or "Let me research that further before giving you a full answer."
This ability to self-regulate, or "self-restrain," is crucial for LLMs, but it's not something they naturally learn through typical training methods. These methods focus on maximizing the likelihood of the next word in a sequence, which doesn't teach the model to modulate its responses based on uncertainty.
To address this, the researchers developed a [utility function](https://aimodels.fyi/papers/arxiv/rejection-improves-reliability-training-llms-to-refuse) that encourages the model to only generate responses when it is confident in them. They also introduced a process called "ReSearch," where the model engages in a kind of "self-reflection" by iteratively prompting itself and evaluating its own responses.
By using this ReSearch process to generate synthetic data and then finetuning the model on that data, the researchers were able to create LLMs that are more selective in their responses. These models generate fewer [hallucinations](https://aimodels.fyi/papers/arxiv/when-hindsight-is-not-2020-testing-limits) – that is, they are less likely to confidently produce factually incorrect information. They can also choose to abstain from answering if they're not sure, rather than guessing.
## Technical Explanation
The researchers' approach, dubbed "[Learn to Refuse](https://aimodels.fyi/papers/arxiv/learn-to-refuse-making-large-language-models)," aims to teach LLMs to dynamically adapt their behavior based on their level of knowledge and uncertainty. They start by defining a utility function that can encourage the model to only generate responses when it is confident in them. This function scores the generation of responses of different lengths, as well as the decision to abstain from answering.
To optimize this utility function, the researchers introduce the "ReSearch" algorithm, which is a process of iterative self-prompting and self-evaluation. The model prompts itself with a series of questions, generates responses, and then evaluates the quality and confidence of those responses. This self-reflective process allows the model to learn when to confidently provide a full answer and when to abstain.
The synthetic data generated by the ReSearch algorithm is then used to finetune the original LLM. Compared to the unmodified model, the resulting models demonstrate a reduced tendency to hallucinate, or generate factually incorrect information, on both known and unknown topics. This is because the models have learned to selectively restrain themselves and only respond when they are confident in their answers.
The researchers also incorporate the ability to abstain directly into the generated samples, allowing the models to explicitly indicate when they are uncertain and prefer not to answer.
## Critical Analysis
The researchers have tackled an important challenge in deploying large language models safely – the ability to dynamically adapt their behavior based on uncertainty. Their approach of using a utility function and a self-reflective "ReSearch" process is a novel and interesting solution.
One potential limitation of the work is that the self-prompting and self-evaluation process used in ReSearch may not fully capture the range of real-world scenarios and uncertainties that an LLM might encounter. The synthetic data generated through this process, while helpful for training, may not be a perfect substitute for the diverse set of situations the model will face in deployment.
Additionally, the researchers do not provide extensive testing of the models' ability to calibrate their confidence and abstention across a wide range of topics and contexts. Further research may be needed to ensure the models' self-restraint capabilities generalize well.
It would also be valuable to see how the researchers' approach compares to other methods for encouraging LLMs to be more cautious and uncertain, such as [rejection sampling](https://aimodels.fyi/papers/arxiv/rejection-improves-reliability-training-llms-to-refuse) or [reflective reinforcement learning](https://aimodels.fyi/papers/arxiv/re2llm-reflective-reinforcement-large-language-model-session).
Overall, the researchers have made a compelling case for the importance of self-restraint in LLMs and have presented a promising approach for teaching this capability. Further exploration and testing of their methods, as well as comparisons to other techniques, could yield valuable insights for the safe deployment of these powerful AI systems.
## Conclusion
The research presented in this paper tackles a crucial challenge in the safe deployment of large language models – the ability to dynamically adapt their behavior based on their level of knowledge and uncertainty. By introducing a utility function and a self-reflective "ReSearch" process, the researchers have developed a method for teaching LLMs to selectively restrain themselves and only generate responses when they are confident in them.
The resulting models demonstrate reduced hallucinations, or factually incorrect outputs, on both known and unknown topics. This is a significant step forward in ensuring the reliability and safety of these powerful AI systems as they are increasingly integrated into real-world applications.
While there are some potential limitations and areas for further research, the researchers' work represents an important contribution to the field of AI safety and reliability. As the capabilities of large language models continue to expand, the ability to imbue them with self-restraint and uncertainty awareness will be critical for their responsible and beneficial deployment in society.

## __Introduction__
In this edition of our security news weekly round-up, the articles that we'll review are mostly about _malware_ and _vulnerabilities_.
So, get ready, and let's get started.
<hr/>
## [Trojanized jQuery Packages Found on npm, GitHub, and jsDelivr Code Repositories](https://thehackernews.com/2024/07/trojanized-jquery-packages-found-on-npm.html)
Yes, some developers and projects still use jQuery. Therefore, if you know one, send them this article. Or, if you're one, read the article and be on the lookout.
If you don't use jQuery, what lesson can you take from the article? The lesson is: Supply Chain attack is real and it can affect anyone. Therefore, education and awareness like this ensure that you are prepared if it happens to you.
The following is a quick excerpt from the article:
> As many as 68 packages have been linked to the campaign. They were published to the npm registry starting from May 26 to June 23, 2024, using names such as cdnjquery, footersicons, jquertyi, jqueryxxx, logoo, and sytlesheets, among others.
## [New Blast-RADIUS attack breaks 30-year-old protocol used in networks everywhere](https://arstechnica.com/security/2024/07/new-blast-radius-attack-breaks-30-year-old-protocol-used-in-networks-everywhere/)
The root of the attack is the use of MD5 by the RADIUS protocol. It's been a long time since security researchers warned us about the insecurity of MD5. Nonetheless, RADIUS still uses it and it seems it has not received the security attention that it deserves despite its popularity.
To get started on your reading journey for this article, the following excerpt sums up what's going on:
> Blast-RADIUS requires the adversary to have the network access needed to act as an active adversary-in-the-middle attacker, meaning the adversary has the ability to read, intercept, block, and modify all data passing between the victim device’s RADIUS client and RADIUS server.
## [Threat actors exploited Windows 0-day for more than a year before Microsoft fixed it](https://arstechnica.com/security/2024/07/threat-actors-exploited-windows-0-day-for-more-than-a-year-before-microsoft-fixed-it/)
In recent versions of Microsoft Windows, Microsoft has made it difficult for end users to open the old Internet Explorer web browser. However, the threat actors in this case used a vulnerability and some social engineering to trick potential victims into launching Internet Explorer. Yes, you read that right.
If they are successful, they can trick the victim into generating an RCE, which is short for [Remote Code Execution](https://www.cloudflare.com/learning/security/what-is-remote-code-execution/).
The following excerpt briefly explains how the vulnerability works:
> “To summarize the attacks from the exploitation perspective: the first technique used in these campaigns is the “mhtml” trick, which allows the attacker to call IE instead of the more secure Chrome/Edge,” Li wrote. “The second technique is an IE trick to make the victim believe they are opening a PDF file, while in fact, they are downloading and executing a dangerous .hta application.
## [New OpenSSH Vulnerability Discovered: Potential Remote Code Execution Risk](https://thehackernews.com/2024/07/new-openssh-vulnerability-discovered.html)
This is different from [regreSSHion](https://blog.qualys.com/vulnerabilities-threat-research/2024/07/01/regresshion-remote-unauthenticated-code-execution-vulnerability-in-openssh-server), but it was discovered during a review of regreSSHion by [Alexander Peslyak](https://en.wikipedia.org/wiki/Solar_Designer). Based on the excerpt below, it seems the impact is not that much.
> So the immediate impact is lower. However, there may be differences in exploitability of these vulnerabilities in a particular scenario, which could make either one of these a more attractive choice for an attacker, and if only one of these is fixed or mitigated then the other becomes more relevant.
## [Apple warns iPhone users in 98 countries of spyware attacks](https://techcrunch.com/2024/07/10/apple-alerts-iphone-users-in-98-countries-to-mercenary-spyware-attacks/)
The article's title says it all, and it turns out that it's not the first time that Apple has done this. This further proves that Apple takes the security of its iPhone users seriously.
Here is an excerpt from the article:
> In its communication to affected users, Apple stressed the sensitive nature of its threat identification methods, cautioning that divulging additional details could potentially aid attackers in evading future detection.
## [Exim vulnerability affecting 1.5 million servers lets attackers attach malicious files](https://arstechnica.com/security/2024/07/more-than-1-5-million-email-servers-running-exim-vulnerable-to-critical-attacks/)
They have fixed the vulnerability. Furthermore, the lesson here is to always be careful of the file attachments that you click in your email no matter how trustworthy it might seem. Be careful.
The following excerpt explains how the vulnerability works (this vulnerability is tracked as CVE-2024-39929):
> CVE-2024-39929 stems from an error in the way Exim parses multiline headers as specified in RFC 2231. Threat actors can exploit it to bypass extension blocking and deliver executable attachments in emails sent to end users. The vulnerability exists in all Exim versions up to and including 4.97.1. A fix is available in the Release Candidate 3 of Exim 4.98.
## [Signal downplays encryption key flaw, fixes it after X drama](https://www.bleepingcomputer.com/news/security/signal-downplays-encryption-key-flaw-fixes-it-after-x-drama/)
This is one of those cases in which you had to fix your application because users took to social media to let the entire world know what was going on. Moreover, a developer already filed a pull request (PR) on April 1, 2024, that can fix the issue.
After the entire incident on Twitter (now called X), Signal fixed the issue and thanked the developer. All these coming after 3 months of filing the PR. Patience is a virtue!
No excerpt can do justice to the article. Go read it and have fun while at it!

## Overview
- Large language models (LLMs) are increasingly being used for a wide range of applications, from information retrieval to content generation and problem-solving.
- Due to the complex and novel behavioral patterns emerging in LLMs, the paper introduces a new field of research called [machine psychology](https://aimodels.fyi/papers/arxiv/psycollm-enhancing-llm-psychological-understanding-evaluation) to thoroughly assess and scrutinize their capabilities.
- Machine psychology aims to discover emergent abilities in LLMs that cannot be detected by traditional natural language processing benchmarks.
## Plain English Explanation
**What are large language models, and why are they important?**
Large language models (LLMs) are advanced artificial intelligence systems that can understand and generate human-like text. They have become increasingly prevalent in our lives, used for various tasks like [information retrieval](https://aimodels.fyi/papers/arxiv/apprentices-to-research-assistants-advancing-research-large), content creation, and problem-solving. As these models continue to grow in sophistication, it's crucial to understand their capabilities and limitations.
**How can psychology help us study LLMs?**
The paper introduces a new field called **machine psychology**, which applies psychological experiments originally designed for humans to study the behavior of LLMs. By treating LLMs as participants in these experiments, researchers can uncover emergent abilities that may not be detected by traditional benchmarks. This allows for a more comprehensive understanding of how these models think and behave.
**What are the goals of machine psychology?**
The primary goal of machine psychology is to discover new and unexpected capabilities in LLMs that go beyond their traditional language processing abilities. By adapting psychological experiments for LLMs, researchers can gain insights into the models' decision-making processes, reasoning skills, and even their potential for [simulating human psychology](https://aimodels.fyi/papers/arxiv/limited-ability-llms-to-simulate-human-psychological). This knowledge can then be used to [assess the nature and limitations of LLMs](https://aimodels.fyi/papers/arxiv/assessing-nature-large-language-models-caution-against) and to [enhance their psychological understanding and evaluation](https://aimodels.fyi/papers/arxiv/psycollm-enhancing-llm-psychological-understanding-evaluation).
## Technical Explanation
The paper outlines the methodology for this new field of **machine psychology**, which involves adapting psychological experiments originally designed for humans to study the behavior of LLMs. By treating LLMs as participants in these experiments, researchers can gain insights into the models' decision-making processes, reasoning skills, and even their potential for [simulating human psychology](https://aimodels.fyi/papers/arxiv/limited-ability-llms-to-simulate-human-psychological).
The paper defines the methodological standards for machine psychology research, with a particular focus on policies for [prompt design](https://aimodels.fyi/papers/arxiv/philosophical-introduction-to-language-models-part-ii). This is crucial, as the way prompts are structured can significantly impact the behavior and responses of LLMs.
Additionally, the paper outlines how the behavioral patterns discovered in LLMs through these experiments should be interpreted. The goal is to uncover emergent abilities in LLMs that cannot be detected by most traditional natural language processing benchmarks, providing a more comprehensive understanding of these models' capabilities and limitations.
## Critical Analysis
The paper raises important points about the need to thoroughly assess the capabilities of LLMs as they become more prevalent in our lives. By introducing the field of machine psychology, the authors offer a novel approach to studying these models that goes beyond traditional benchmarks.
However, the paper also acknowledges the potential limitations of this approach. Adapting psychological experiments for LLMs may not always yield accurate or meaningful insights, as the models may not truly "experience" the experiments in the same way as humans. Additionally, the interpretation of the behavioral patterns discovered in LLMs can be challenging and may require further research.
It's also important to consider the broader implications of understanding LLM capabilities, both in terms of their potential benefits and their potential [risks or limitations](https://aimodels.fyi/papers/arxiv/assessing-nature-large-language-models-caution-against). As these models become more integrated into our lives, it's crucial to approach their development and deployment with caution and a nuanced understanding of their capabilities and limitations.
## Conclusion
The paper's introduction of the field of machine psychology represents a significant step forward in the comprehensive assessment of LLM capabilities. By adapting psychological experiments for these models, researchers can uncover emergent abilities that may not be detected by traditional benchmarks, providing a more holistic understanding of how LLMs think and behave.
While this approach has its limitations, the insights gained from machine psychology research can inform the responsible development and deployment of LLMs, ensuring that these powerful tools are used in ways that benefit society while mitigating potential risks. As LLMs continue to evolve and become increasingly intertwined with our daily lives, this type of rigorous, interdisciplinary research will be essential for navigating the complex landscape of artificial intelligence.

## Overview
- Heuristics are commonly used in software systems to make important decisions, but can be costly to replace with machine learning (ML) solutions
- SmartChoices is a novel approach that reduces the cost of deploying production-ready ML solutions for contextual bandits problems
- SmartChoices provides a clean interface to separate problem formulation from implementation details, enabling non-experts to rapidly deploy ML-powered solutions
## Plain English Explanation
Software systems often use simple rules, or **[heuristics](https://aimodels.fyi/papers/arxiv/leveraging-automatic-strategy-discovery-to-teach-people)**, to make decisions that have a big impact on overall system performance. For example, heuristics might be used to decide which items to keep in a cache, how to schedule tasks, or what information to display to users. While **[machine learning (ML)](https://aimodels.fyi/papers/arxiv/frugal-algorithm-selection)** could potentially outperform these heuristics, actually replacing them in a production system can be extremely difficult and costly.
**SmartChoices** is a new approach that makes it easier and more affordable to use ML to improve decision-making in software systems. It provides a straightforward way for engineers to define the key elements of their problem, like the information that's available (the "context"), the possible actions (the "arms"), and the feedback on how well those actions perform. SmartChoices then handles the complex tasks of encoding and logging the data, training ML models, and deploying the optimized decision policies.
This allows engineers who aren't ML experts to rapidly incorporate production-ready **[ML-powered solutions](https://aimodels.fyi/papers/arxiv/automating-data-annotation-under-strategic-human-agents)** into their software, without having to worry about the technical details. SmartChoices has already been used to improve a wide range of applications, leading to better performance in areas like latency, throughput, and user engagement.
## Technical Explanation
SmartChoices is designed to simplify the process of deploying **[contextual bandits](https://aimodels.fyi/papers/arxiv/towards-bayesian-data-selection)** - a type of ML model - to make optimized decisions in production software systems. Engineers define their problem by specifying the relevant data types for the context, available actions, and feedback, then SmartChoices handles the rest.
Under the hood, SmartChoices uses efficient data encoding and logging techniques to capture the necessary information. It then trains and evaluates various contextual bandit models, automatically selecting the best-performing one and deploying it. This allows SmartChoices to provide valuable features like online learning, exploration-exploitation balancing, and A/B testing out of the box.
By encapsulating best practices for contextual bandits in a shared library, SmartChoices enables **[non-ML experts](https://aimodels.fyi/papers/arxiv/learning-personalized-decision-support-policies)** to rapidly integrate production-ready ML solutions into their software. The authors demonstrate how SmartChoices has been used to improve a range of applications, including caching, batch processing, and user interface layouts.
## Critical Analysis
The SmartChoices approach appears to be a promising way to lower the barrier to adopting ML-powered decision-making in production software. By providing a clean abstraction and handling the technical complexities, it enables a wider range of engineers to benefit from contextual bandits without extensive ML expertise.
However, the paper doesn't delve deeply into the specific ML models and techniques used under the hood. While the authors claim their implementation is efficient enough for low-level applications, more details on the performance characteristics and limitations would be helpful. Additionally, the paper doesn't address how SmartChoices would handle more complex or domain-specific problem formulations that don't fit neatly into the contextual bandits framework.
Further research could explore ways to expand the flexibility and generalizability of the SmartChoices approach, perhaps by allowing more customization of the ML components or supporting a broader range of decision-making problems. Evaluating the long-term maintainability and scalability of the system in production environments would also be valuable.
## Conclusion
**SmartChoices** presents a novel approach to simplifying the deployment of ML-powered decision-making in production software systems. By providing a clean interface that separates problem formulation from implementation details, it enables non-ML experts to rapidly integrate optimized policies into their applications. The authors demonstrate how SmartChoices has been used to improve a variety of software, leading to better performance in areas like latency, throughput, and user engagement.
While the paper lacks some technical details, the overall concept of SmartChoices is promising and could have significant implications for making ML more accessible and practical for a wider range of software engineers. Further research to expand the flexibility and generalizability of the approach could unlock even broader applications and benefits.

## Overview
- Quantum machine learning is a promising area of research, but a major challenge is that quantum models require access to a quantum computer for deployment.
- This paper introduces a new class of quantum models where quantum resources are only needed during the training phase, while the deployed model can run on classical hardware.
- The authors prove that this approach can provide learning advantages over fully classical models, under certain assumptions.
- This makes quantum machine learning more practical for real-world applications by enabling classical deployment.
## Plain English Explanation
[This paper explores a new way to use quantum computers for machine learning.](https://aimodels.fyi/papers/arxiv/machine-learning-quantum-computing-specialists) Quantum computers have the potential to perform certain computations much faster than classical computers, and this could give them an advantage in machine learning tasks. However, a major challenge is that even after a quantum machine learning model is trained, it still requires access to a quantum computer to make predictions on new data.
To address this, the researchers developed a new type of quantum model where the quantum resources are only used during the training phase. Once the model is trained, they generate a "shadow model" that can be deployed on classical hardware. [This allows the benefits of quantum machine learning to be realized without the need for continuous access to a quantum computer.](https://aimodels.fyi/papers/arxiv/quantum-machine-learning-near-term-quantum-devices)
The researchers prove that this approach is still powerful enough to provide learning advantages over fully classical models, under certain assumptions from complexity theory. This is an important step towards making [quantum machine learning more practical and widely applicable.](https://aimodels.fyi/papers/arxiv/machine-learning-applications-quantum-computing-review)
## Technical Explanation
The key idea is to develop a class of quantum machine learning models where the quantum resources are only required during the training phase. After training, the model is converted into a "shadow model" that can be deployed on classical hardware.
Specifically, the training of these models involves a quantum subroutine that generates a probability distribution. This distribution is then used to train a classical machine learning model. The authors prove that this approach is still powerful enough to achieve a learning advantage over fully classical models, under certain assumptions from complexity theory.
[This approach addresses a major obstacle to the practical deployment of quantum machine learning models.](https://aimodels.fyi/papers/arxiv/adversarial-robustness-guarantees-quantum-classifiers) By decoupling the training and deployment phases, it enables the benefits of quantum computation to be realized without the need for continuous access to a quantum computer.
[The authors also show that this class of models is "universal" for classically-deployed quantum machine learning, meaning it can capture the full range of such models.](https://aimodels.fyi/papers/arxiv/exploring-quantum-enhanced-machine-learning-computer-vision) However, they note that it does have restricted learning capacities compared to "fully quantum" models.
## Critical Analysis
The paper provides a compelling approach to making quantum machine learning more practical and accessible. By separating the training and deployment phases, it addresses a key challenge that has limited the real-world application of these techniques.
One potential limitation is that the authors acknowledge their approach has reduced learning capacity compared to fully quantum models. It would be interesting to understand the magnitude of this tradeoff and the types of tasks where it might be most significant.
Additionally, the analysis relies on certain complexity-theoretic assumptions, which, while widely believed, are not yet proven. Further research may be needed to fully validate the learning advantages claimed in the paper.
Overall, this work represents an important step forward in bridging the gap between the promise of quantum machine learning and its practical implementation. It encourages critical thinking about the various tradeoffs and considerations involved in deploying these powerful techniques in real-world settings.
## Conclusion
This paper introduces a new approach to quantum machine learning that decouples the training and deployment phases. By only requiring quantum resources during training, it enables the benefits of quantum computation to be realized without the need for continuous access to a quantum computer.
The authors prove that this class of models can still provide learning advantages over fully classical models, under certain assumptions. This represents a significant advance towards making [quantum machine learning more practical and widely applicable across a range of domains.](https://aimodels.fyi/papers/arxiv/machine-learning-applications-quantum-computing-review)
While the approach does have some limitations compared to fully quantum models, it opens up new possibilities for the real-world use of these powerful techniques. As quantum hardware continues to evolve, innovations like this will be crucial for unlocking the full potential of [quantum-enhanced machine learning.](https://aimodels.fyi/papers/arxiv/exploring-quantum-enhanced-machine-learning-computer-vision)

## Overview
- This paper explores the impact of input length on the reasoning performance of large language models (LLMs) when completing the same task.
- The researchers investigate how increasing the amount of textual input affects an LLM's ability to reason and provide accurate responses.
- They examine factors like the model's capacity to maintain context, extract relevant information, and draw logical conclusions from longer inputs.
## Plain English Explanation
Large language models (LLMs) are powerful AI systems that can understand and generate human-like text. Researchers in this study wanted to see how the length of the text given to an LLM affects its ability to reason and provide accurate responses.
Typically, LLMs are trained on large amounts of text data, which allows them to learn patterns and relationships in language. However, when presented with longer input texts, LLMs may struggle to maintain the full context and extract the most relevant information to answer a question or complete a task.
The researchers in this paper explored what happens when you give an LLM more text to work with - does it perform better at reasoning and providing accurate responses? They designed experiments to test this by giving the same task to the LLM but with varying amounts of input text.
By [understanding the impact of input length on LLM reasoning](https://aimodels.fyi/papers/arxiv/impact-reasoning-step-length-large-language-models), we can learn more about the capabilities and limitations of these powerful AI systems. This knowledge can then inform how we design tasks and prompts to get the best performance from LLMs in real-world applications.
## Technical Explanation
The researchers conducted a series of experiments to investigate the impact of input length on the reasoning performance of large language models (LLMs). They used a diverse set of reasoning tasks, including question answering, logical inference, and common sense reasoning.
For each task, the researchers varied the length of the input text provided to the LLM, ranging from short prompts to longer, more contextual passages. They then compared the model's performance across these different input lengths to understand how the amount of textual information affects its ability to reason and provide accurate responses.
The results showed that, in general, increasing the input length led to improved reasoning performance for the LLMs. With more context to draw from, the models were better able to maintain the relevant information, extract the most salient details, and apply logical reasoning to arrive at the correct answer.
However, the researchers also observed that there were practical limits to the performance gains from longer inputs. At a certain point, the models began to struggle to effectively process and integrate the additional information, leading to diminishing returns or even decreased accuracy.
These findings align with previous research on [the challenges LLMs face with long-context learning](https://aimodels.fyi/papers/arxiv/long-context-llms-struggle-long-context-learning) and the need for [techniques to extend the context capabilities of these models](https://aimodels.fyi/papers/arxiv/beyond-limits-survey-techniques-to-extend-context).
The researchers also discussed potential approaches, such as the [XL3M framework](https://aimodels.fyi/papers/arxiv/xl3m-training-free-framework-llm-length-extension) and the [BabiLong system](https://aimodels.fyi/papers/arxiv/babilong-testing-limits-llms-long-context-reasoning), which aim to address the limitations of LLMs in handling long-form inputs and reasoning over extended contexts.
## Critical Analysis
The researchers in this paper provide valuable insights into the impact of input length on the reasoning performance of large language models (LLMs). Their experimental design and analysis offer a nuanced understanding of the capabilities and limitations of these AI systems when faced with varying levels of contextual information.
One potential area for further research is the exploration of task-specific differences in the relationship between input length and reasoning performance. The paper suggests that certain types of reasoning tasks may be more or less sensitive to changes in input length, and a deeper investigation into these task-specific dynamics could yield additional insights.
Additionally, the researchers acknowledge the need for continued advancements in techniques to extend the context capabilities of LLMs, as the practical limits observed in their experiments highlight the ongoing challenges in this area. Exploring and evaluating emerging approaches, such as the XL3M framework and BabiLong system, could help advance the state of the art in long-context reasoning for large language models.
Overall, this paper contributes to our understanding of the factors that influence the reasoning capabilities of LLMs, which is crucial as these models become increasingly prevalent in real-world applications. By critically examining the impact of input length, the researchers provide a foundation for the development of more robust and adaptable language models that can effectively reason across a wide range of contexts.
## Conclusion
This research paper provides valuable insights into the impact of input length on the reasoning performance of large language models (LLMs). The findings suggest that increasing the amount of textual information available to an LLM can generally improve its ability to reason and provide accurate responses, but there are practical limits to these performance gains.
By understanding the relationship between input length and reasoning, researchers and practitioners can develop more effective strategies for designing tasks and prompts that leverage the full capabilities of LLMs. This knowledge can also inform the development of advanced techniques, such as the XL3M framework and BabiLong system, which aim to extend the context handling abilities of these powerful AI models.
As large language models continue to play a crucial role in various applications, this research contributes to the ongoing efforts to push the boundaries of their reasoning and context-processing capabilities. By critically examining the factors that influence LLM performance, the scientific community can work towards building more robust and adaptable language models that can reliably reason and make decisions across a wide range of real-world scenarios.

## Overview
- Explores the concept of "simulacra" in the context of AI language models and anthropomorphic interactions
- Examines the interplay between human perceptions, AI capabilities, and the blurring of reality and simulation
- Discusses the ethical and philosophical implications of AI systems that exhibit lifelike behaviors and attributes
## Plain English Explanation
This paper delves into the idea of "simulacra" - representations or simulations that become indistinguishable from the real thing. The authors explore how this concept applies to modern AI language models and the anthropomorphic interactions that can occur between humans and these AI systems.
As AI models become increasingly advanced, they can exhibit behaviors and responses that seem remarkably human-like. This can lead to a blurring of the line between reality and simulation, where users may have a hard time discerning whether they are interacting with a sentient being or a highly sophisticated imitation. The paper examines the ethical and philosophical implications of these "conscious exotica" - AI systems that appear to possess human-like qualities, but whose true nature remains uncertain.
The authors delve into topics such as [language models and AI](https://aimodels.fyi/papers/arxiv/computation-meaning-language-models-incomprehensible-horrors), [anthropomorphism and role-play](https://aimodels.fyi/papers/arxiv/anticipating-user-needs-insights-from-design-fiction), and the broader questions of [artificial consciousness](https://aimodels.fyi/papers/arxiv/artificial-consciousness-some-logical-conceptual-preliminaries) and [embodied cognition](https://aimodels.fyi/papers/arxiv/introducing-brain-like-concepts-to-embodied-hand). The paper encourages readers to consider the implications of these developments and to approach the interactions with AI systems with a critical yet open-minded perspective.

- The paper also discusses the key challenges and opportunities in leveraging LLMs for this important task, which has significant implications for software security.
## Plain English Explanation
Computers and software are essential parts of our daily lives, powering everything from banking apps to social media. However, sometimes there can be unintended weaknesses or "vulnerabilities" in the code that power these applications, which can be exploited by bad actors to cause harm. [Detecting these vulnerabilities early is crucial for keeping our digital world secure.](https://aimodels.fyi/papers/arxiv/harnessing-large-language-models-software-vulnerability-detection)
Recently, researchers have been exploring the use of powerful AI language models, known as large language models (LLMs), to help automate the process of finding vulnerabilities in code. These models are trained on massive amounts of text data and can understand and generate human-like language. The hope is that they can be applied to scan code and identify potential security risks.
This paper takes a close look at the current state of this technology. The authors evaluate several state-of-the-art LLM-based vulnerability detection models, testing them on different benchmark datasets to understand their strengths and limitations. [They find that while these models show promise, there are still significant challenges to overcome before they can be reliably deployed in real-world software development.](https://aimodels.fyi/papers/arxiv/revisiting-performance-deep-learning-based-vulnerability-detection)
For example, the models can struggle to generalize beyond the specific types of vulnerabilities they were trained on, and may miss subtle variations or new types of vulnerabilities. There are also concerns about the interpretability and trustworthiness of these AI-powered vulnerability detectors.
Overall, the paper provides a nuanced and detailed look at the current state of this important research area. It highlights the potential of LLMs for security, but also cautions that there is still a lot of work to be done to make these tools reliable and practical for real-world software development.
## Technical Explanation
This paper presents a comprehensive evaluation of several state-of-the-art large language model (LLM)-based vulnerability detection models across different benchmark datasets. The authors assess the models' performance in terms of their ability to accurately identify various types of security vulnerabilities in code.
The paper begins by providing background on the key challenges in using LLMs for vulnerability detection. These include the models' tendency to overfit to specific vulnerability patterns, the difficulty in interpreting their decision-making, and the need for strong generalization capabilities to handle the vast diversity of potential vulnerabilities. [The authors also discuss the importance of developing robust evaluation methodologies to properly assess the capabilities and limitations of these models.](https://aimodels.fyi/papers/arxiv/vuldetectbench-evaluating-deep-capability-vulnerability-detection-large)
The core of the paper is a detailed experimental evaluation of several LLM-based vulnerability detection models, including [CLDR](https://aimodels.fyi/papers/arxiv/generalization-enhanced-code-vulnerability-detection-via-multi), [VulDetector](https://aimodels.fyi/papers/arxiv/harnessing-large-language-models-software-vulnerability-detection), and [SecureBERT](https://aimodels.fyi/papers/arxiv/security-vulnerability-detection-multitask-self-instructed-fine). The authors test these models on a range of benchmark datasets, such as [SARD](https://samate.nist.gov/SARD/index.php) and [VulDeePecker](https://github.com/CGCL-codes/VulDeePecker), to assess their performance on different types of vulnerabilities.
The results reveal both the strengths and limitations of these LLM-based approaches. While the models generally outperform traditional vulnerability detection techniques, they struggle to maintain high performance when evaluated on more diverse and challenging datasets. The authors attribute this to the models' tendency to overfit to specific vulnerability patterns and their limited ability to generalize to new, unseen vulnerability types.
[The paper also discusses the importance of interpretability and trustworthiness in vulnerability detection models, as these systems can have significant real-world consequences.](https://aimodels.fyi/papers/arxiv/revisiting-performance-deep-learning-based-vulnerability-detection) The authors highlight the need for further research to improve the transparency and explainability of LLM-based vulnerability detectors.
## Critical Analysis
The paper provides a valuable and nuanced assessment of the current state of LLM-based vulnerability detection, highlighting both the promise and limitations of this approach. The authors' comprehensive evaluation across multiple benchmark datasets is a key strength, as it allows for a more holistic understanding of the models' capabilities and shortcomings.
One of the paper's key insights is the models' tendency to overfit to specific vulnerability patterns, which limits their ability to generalize to new, unseen vulnerabilities. This is a critical challenge that must be addressed for these models to be truly useful in real-world software development. The authors' discussion of the need for improved interpretability and trustworthiness is also well-founded, as the consequences of false positives or missed vulnerabilities can be severe.
However, the paper could have delved deeper into some of the potential causes of the models' limitations, such as the inherent complexity and diversity of vulnerabilities, the quality and size of the training data, or the architectural choices of the models themselves. Additionally, the paper could have explored potential avenues for addressing these challenges, such as [improved data augmentation techniques](https://aimodels.fyi/papers/arxiv/generalization-enhanced-code-vulnerability-detection-via-multi) or [novel model architectures](https://aimodels.fyi/papers/arxiv/security-vulnerability-detection-multitask-self-instructed-fine).
Overall, this paper provides a valuable contribution to the ongoing research on leveraging LLMs for vulnerability detection. It highlights the significant progress made in this area, while also cautioning about the remaining challenges that must be overcome to realize the full potential of this technology for software security.
## Conclusion
This paper presents a comprehensive evaluation of the current state of large language model (LLM)-based vulnerability detection, shedding light on both the promise and limitations of this approach. The authors' detailed assessment of several state-of-the-art models across different benchmark datasets reveals that while these models outperform traditional techniques, they still struggle to maintain high performance on more diverse and challenging data.

For beginners who would like to get started with Laravel, i'll provide the most crucial snippets of code that you will encounter in this amazing framework
**Prerequisites**
1. PHP: Laravel requires PHP 8.0 or later.
2. Composer: This is a dependency manager for PHP
3. Web server: Apache, Nginx, or Laravel's built-in-server
Start your XAMPP web server since this will be required for the database
Creatae a new project using composer directly. Replace project-name with the desired name
```
composer create-project --prefer-dist laravel/laravel project-name
```
cd project-name
```
cd project-name
```
Serve the Application
```
php artisan serve
```
This command will start the development server at 'http://localhost:8000'.
**Configure your environemnt**
Laravel uses a **'.env** file for environmental configuaration. Open the **'.env'** file in the root of your project and configure your database and other settings
As for the latest installation it comes with sqlite by default but i prefer using mysql so we are going to change that
This is what it looks like by default
```
DB_CONNECTION=sqlite
# DB_HOST=127.0.0.1
# DB_PORT=3306
# DB_DATABASE=laravel
# DB_USERNAME=root
# DB_PASSWORD=
```
change it to, make sure to uncomment the commented parts
```
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laravel-dev-database
DB_USERNAME=root
DB_PASSWORD=
```
**Run migrations**
Laravel uses migrations to create database tables. Run the migration with
```
php artisan migrate
```
**Laravel uses MVC (Model, View, Controller) Architecture**
We are going to discuss this in a moment
Congratulations, you have successfully created your first Laravel application.

1,921,662 | Building PDF Open Source Services with Angular & GCP — Handling long processing tasks | Welcome to the first part of the journey in building open source PDF service using Angular... | 28,051 | 2024-07-12T20:52:06 | https://dev.to/dalenguyen/building-pdf-open-source-services-with-angular-gcp-handling-long-processing-tasks-3fhh | angular, webdev, gcp, firebase | Welcome to the first part of the journey in building open source PDF service using Angular (Analogjs), Firestore, Cloud Storage, and CloudRun. This project serves as a platform for sharing my knowledge, continually learning best practices, and simultaneously contributing to the community.
Demo: https://pdfun.xyz
GitHub: https://github.com/dalenguyen/pdfun
The solution is built around GCP ecosystem, it’s better to deploy the project on GCP, so it can access their services. There are two parts of the solution:
- Web UI (Analogjs — Angular): handle user interaction
- Backend (Node — Express): process PDF files
Building PDF services involves uploading, downloading, and processing PDF files, which can take significant time. This article will explore methods for handling these long processing tasks efficiently.
## Normal API Requests and Their Pitfalls
Typically, when a client makes an API request, the server processes the request and sends back a response. This synchronous approach works well for short tasks. However, it has its pitfalls when it comes to long processing tasks.
The main issue is that the client has to wait for the server to complete the task before it can receive a response. This can lead to a poor user experience, especially if the task takes a long time to complete.
Additionally, most browsers and client-side libraries have a timeout limit for API requests. If the server doesn’t respond within this limit, the request is automatically cancelled.
## Maximum Timeout from the Client Side
The maximum timeout for an API request varies depending on the client-side library or browser. For instance, the default timeout in Angular’s HttpClient is 0, which means it waits indefinitely for a response. However, [browsers like Chrome](https://source.chromium.org/chromium/chromium/src/+/main:net/socket/client_socket_pool.cc;l=41) and Firefox have a maximum timeout of around 300 seconds (5 minutes). If the server doesn’t respond within this timeframe, the request is terminated.
## Common Methods to Handle Long Requests from Client Side
There are several methods to handle long requests from the client side:
1. Polling: The client makes a request to the server and then periodically sends follow-up requests to check if the task is complete.
2. Long Polling: The client makes a request to the server, which holds the request open until the task is complete or a timeout occurs.
3. WebSockets: A persistent, two-way communication channel is established between the client and server, allowing the server to send a response when the task is complete.
4. Server-Sent Events: The server sends updates to the client over a single, long-lived connection.
While these methods can be effective, they also have their drawbacks, such as increased complexity and potential for resource inefficiency.
### Example of Polling
Here is an example of implementing polling in Angular.
```
// polling.component.ts
INTERVAL = 2000; // 2 seconds
data = signal({});
timer(0, this.INTERVAL)
.pipe(
// stop the API request
takeUntil(this.stopTimer$),
delay(1000),
// function to get data from the server
switchMap(() => this.getData()),
// retry if error happened
retry()
)
.subscribe({
next: (res: any) => {
if (res.status === 'SUCCEED') {
this.stopTimer$.next(true);
}
this.data.set(res);
},
error: (error: Error) => {
this.errorMessage.set(error.message);
},
});
```
The function utilize `timer` operator from rxjs to run an interval (2s) to retrieve data from the server by using `getData()`. It can be stopped by emitting the `stopTimer$` when the component is destroyed or the desired data is retrieved.
### Example of SSE (Server-sent events)
Here is an example of implementing SSE from the server:
```
// server (Analogjs - Nitro server)
export default defineEventHandler(async (event) => {
const eventStream = createEventStream(event);
const interval = setInterval(async () => {
await eventStream.push(`Message @ ${new Date().toLocaleTimeString()}`);
}, 1000);
eventStream.onClosed(async () => {
clearInterval(interval);
await eventStream.close();
});
return eventStream.send();
});
```
We utilizing `createEventStream` to create a stream and set an interval (1s) as example to stream string data from server to the client.
Let’s have a look at the client implementation:
```
constructor() {
// using afterNextRender to make sure the code is running from the browser
afterNextRender(() => {
this.eventSource = new EventSource('/api/v1/sse');
this.eventSource.onmessage = (event) => {
this.data.set(event.data);
};
});
}
ngOnDestroy() {
this.eventSource?.close();
}
```
We create an event source using `EventSource` that points to our server. After that, we can listen to data from the server by using `this.eventSource.onmessage` callback method.
## Utilizing GCP Cloud Run and Firestore to Handle Long Requests
Google Cloud Platform (GCP) offers powerful tools to handle long processing tasks. Specifically, we can leverage Cloud Run and Firestore.
Here’s the architecture flow for the PDF resize service:
You read the first article to understand more about this PDF resize service.
By utilizing Firestore, we don’t have implement polling or server-sent events ourself which is much more convenient. This is the beauty of Backend as service 😉.
From the frontend, we can observe data changes from the Firestore and allow user to download resized file when it’s ready. Let’s have a look at the example code:
```
// the code is simplified for better understaind.
docRef = doc(this.firestore, `${this.generateFilePath()}/${this.currentID()}`)
pdf = computed(() => {
// return an observable of data
return docData(this.docRef()) as Observable<UploadedFile>
})
downloadUrl$ = this.pdf().pipe(
// only get data with taskReponse object
filter((doc) => Object.keys(doc?.taskResponse ?? {}).length > 0),
switchMap((doc) => {
// handling & validate response data
return this.getDownloadLink(
`${doc.filePath}/${doc.taskResponse?.fileName}`,
)
}),
)
```
All we need to do is to create a listener from our frontend code, and the server will send the data back to us when it’s ready! You can test it out at [https://pdfun.xyz](https://pdfun.xyz).
In conclusion, handling long processing tasks in web development can be challenging, but with the right tools and strategies, it’s definitely manageable. By leveraging the power of Angular and GCP, we can build robust PDF open source services that handle long processing tasks effectively and efficiently. Happy coding! | dalenguyen |

https://heysensei.app
## Introduction
Recently, I embarked on a journey to build an open-source Perplexity AI using NextJS and open-source Large Language Models (LLMs). This project combined the power of modern web development with the capabilities of state-of-the-art AI models, aiming to create a versatile, efficient, and user-friendly application. Here's a detailed look at the development side of things.
## Project Overview
The project, named "Sensei," can be found on [GitHub](https://github.com/jjleng/sensei/tree/main). It leverages NextJS for the frontend and open-source LLMs for natural language processing. The main goal was to build a Perplexity AI, a search data-based Retrieval-Augmented Generation (RAG) agent, using completely open-source technologies.
## Why NextJS?
NextJS was a natural choice for this project due to its robust features, including server-side rendering, static site generation, and API routes. These features provided the flexibility and performance needed to handle the dynamic interactions and real-time data processing required by the AI components.
## Tailwind CSS and shadcn for Styling
One of my key decisions was to avoid using a traditional component library and instead build the UI with Tailwind CSS and shadcn. Here’s why this combination turned out to be a productive choice:
- **Utility-First Approach:** Tailwind's utility-first approach allowed for rapid prototyping and easy adjustments, making the development process more efficient.
- **Customizability:** Tailwind provided the flexibility to create custom styles without being constrained by predefined components.
- **Component-Based Development:** shadcn offered a set of highly customizable and accessible components, making it easier to maintain consistency and build a polished UI.
- **Responsive Design:** Built-in responsive design utilities helped in creating a seamless experience across different devices.
## Building the Frontend
The frontend of the application focused on creating an intuitive user interface that facilitates seamless interaction with the AI.
## Flow Engineering Over Function Calling
Instead of relying on function calling, the application leverages flow engineering. This approach simplifies the interaction between the frontend and the AI models, reducing complexity and improving performance. The decision to use flow engineering was driven by the need to handle long RAG prompts effectively.
## Learnings and Challenges
1. **Context Window Length:** Handling long context windows was challenging but crucial for providing accurate responses. Ensuring the AI could process large amounts of data without losing context was a key focus.
2. **Instruction Following:** Many open-source models struggled with following complex instructions. Prompt engineering and extensive testing were necessary to achieve desired results.
3. **Mix of Agents:** Using a mix of lighter and heavier models helped reduce the Time to First Byte (TTFB), but it also introduced challenges related to language support and consistency in responses.
## Conclusion
Building Perplexity AI with NextJS and open-source LLMs was a rewarding experience. The combination of modern web development techniques and advanced AI capabilities resulted in a powerful and flexible application. Tailwind CSS and shadcn proved to be an excellent choice for styling, enabling rapid development and a responsive design.
If you're interested in the project, you can check it out on [GitHub](https://github.com/jjleng/sensei/tree/main). I'm excited to continue improving it and exploring more ways to integrate open-source technologies in meaningful ways.

1,921,669 | Running Llama 3, Mixtral, and GPT-4o | There are so many different ways to run the G-Generation part of RAG! Today I’ll show a few ways to... | 0 | 2024-07-16T16:00:00 | https://zilliz.com/blog/running-llama-3-mixtral-gpt-4o | ai, rag, machinelearning, tutorial | There are so many different ways to run the G-Generation part of RAG! Today I’ll show a few ways to run some of the hottest contenders in this space: Llama 3 from Meta, Mixtral from Mistral, and the recently announced GPT-4o from OpenAI.
As we can see from the [LMSYS Leaderboard](https://chat.lmsys.org/?leaderboard) below, the gap (in light blue) between closed-source models and open-source models just took a widening hit this week with OpenAI’s new announcement.
Image source: <https://twitter.com/maximelabonne> based on <https://chat.lmsys.org/?leaderboard>.
Outline for this blog:
- The fastest ways to run open-source Llama 3 or Mixtral
- Locally with Ollama
- Anyscale endpoints
- OctoAI endpoint
- Groq endpoint
- Run the latest gpt-4o from OpenAI
- Evaluate answers: GPT-4o, Llama 3, Mixtral
Let’s get started!
## Run Llama 3 Locally using Ollama
First, run RAG the usual way, up to the last step, where you generate the answer, the G-part of RAG. We have many tutorials for getting started with [RAG, including this one](https://github.com/milvus-io/bootcamp/blob/master/bootcamp/workshops/dbta_may_2024/1.%20RAG_basic.ipynb) in Python.
To run Llama 3 locally using Ollama.
1. Follow the [instructions](https://github.com/ollama/ollama) to install ollama and pull a model.
2. That page says `ollama run llama3` will by default pull the latest "instruct" model, which is fine-tuned for chat/dialogue use cases AND fits on your computer. Run that command.
3. For Python, `pip install ollama`.
4. In your RAG Python code, define a Prompt and a Question, and invoke the API call to your locally installed Llama 3 model.
In my case, I have an M2 16GB laptop, so **the downloaded Ollama model is the highest quantized gguf-compiled version of Llama3-8B**. That is, a very small version of Llama 3 is now installed on my laptop!
```
# Separate all the context together by space, reverse order.
# See “Lost in the middle” arxiv.org paper.
contexts_combined = ' '.join(reversed(contexts))
source_combined = ' '.join(reversed(sources))
# Define a Prompt.
SYSTEM_PROMPT = f"""Given the provided Context, your task is to
understand the content and accurately answer the question based
on the information available in the context.
Provide a complete, clear, concise, relevant response in fewer
than 4 sentences and cite the unique Sources.
Answer: The answer to the question.
Sources: {source_combined}
Context: {contexts_combined}
"""
# Send the Question and Prompt to local! llama 3 chat.
import ollama
start_time = time.time()
response = ollama.chat(
messages=[
{"role": "system", "content": SYSTEM_PROMPT,},
{"role": "user", "content": f"question: {SAMPLE_QUESTION}",}
],
model='llama3',
stream=False,
options={"temperature": TEMPERATURE, "seed": RANDOM_SEED,
"top_p": TOP_P,
# "max_tokens": MAX_TOKENS, # not recognized
"frequency_penalty": FREQUENCY_PENALTY}
)
ollama_llama3_time = time.time() - start_time
pprint.pprint(response['message']['content'].replace('\n', ' '))
print(f"ollama_llama3_time: {format(ollama_llama3_time, '.2f')} seconds")
```
The answer looks pretty good; I see three parameters, but only the citation looks garbled. The local model took 13 seconds to run inference on my laptop, but the cost was free.
## Run Llama 3 from Anyscale endpoints
To run Llama 3 inference from Anyscale endpoints:
1. Follow the instructions on the [Anyscale endpoints](https://github.com/simonw/llm-anyscale-endpoints) github page to install the command line and then install the plugin.
2. Get your Anysclae endpoint API token and [update your environment variables](https://help.openai.com/en/articles/5112595-best-practices-for-api-key-safety).
3. For Python, `pip install openai`.
4. Read about the Llama 3 model downloaded from [HuggingFace](https://huggingface.co/meta-llama/Meta-Llama-3-8B-Instruct) and invoke it using the OpenAI API. I used the default Llama 3 on Anyscale playground, which was a 70B-Instruct model.
```
import openai
LLM_NAME = "meta-llama/Llama-3-70b-chat-hf"
anyscale_client = openai.OpenAI(
base_url = "https://api.endpoints.anyscale.com/v1",
api_key=os.environ.get("ANYSCALE_ENPOINT_KEY"),
)
start_time = time.time()
response = anyscale_client.chat.completions.create(
messages=[
{"role": "system", "content": SYSTEM_PROMPT,},
{"role": "user", "content": f"question: {SAMPLE_QUESTION}",}
],
model=LLM_NAME,
temperature=TEMPERATURE,
seed=RANDOM_SEED,
frequency_penalty=FREQUENCY_PENALTY,
top_p=TOP_P,
max_tokens=MAX_TOKENS,
)
llama3_anyscale_endpoints_time = time.time() - start_time
# Print the response.
pprint.pprint(response.choices[0].message.content.replace('\n', ' '))
print(f"llama3_anyscale_endpoints_time: {format(llama3_anyscale_endpoints_time, '.2f')} seconds")
```
The answer looks good, including a perfect citation. The HuggingFace Llama 3 70B took ~6 seconds to invoke from Anyscale endpoints.
## Run Llama 3 from OctoAI Endpoints
To run Llama 3 inference from OctoAI endpoints:
1. Go to <https://octoai.cloud/text>, choose the [Llama 3 8B model](https://octo.ai/models/), click on the model link and you’ll see sample code.
2. Get your OctoAI endpoint [API token](https://octoai.cloud/settings) and [update your environment variables](https://help.openai.com/en/articles/5112595-best-practices-for-api-key-safety).
3. For Python, `pip install octoai`.
4. Read about the [Llama 3 8B model](https://huggingface.co/meta-llama/Meta-Llama-3-8B-Instruct) downloaded from Meta and invoke it.
```
from octoai.text_gen import ChatMessage
from octoai.client import OctoAI
LLM_NAME = "meta-llama-3-70b-instruct"
octoai_client = OctoAI(
api_key=os.environ.get("OCTOAI_TOKEN"),
)
start_time = time.time()
response = octoai_client.text_gen.create_chat_completion(
messages=[
ChatMessage(
content=SYSTEM_PROMPT,
role="system"
),
ChatMessage(
content=SAMPLE_QUESTION,
role="user"
)
],
model=LLM_NAME,
temperature=TEMPERATURE,
# seed=RANDOM_SEED, # not recognized
frequency_penalty=FREQUENCY_PENALTY,
top_p=TOP_P,
max_tokens=MAX_TOKENS,
)
llama3_octai_endpoints_time = time.time() - start_time
# Print the response.
pprint.pprint(response.choices[0].message.content.replace('\n', ' '))
print(f"llama3_octai_endpoints_time: {format(llama3_octai_endpoints_time, '.2f')} seconds")
```
The answer looks good and the citation is perfect. The Llama 3 70B took under ~4 seconds to invoke from OctoAI endpoints.
## Run Llama 3 from Groq LPU endpoints
To run Llama 3 inference from Groq endpoints:
1. Go to [console.groq.com](http://console.groq.com) and follow the instructions.
2. Get your Groq endpoint[ API token](https://console.groq.com/keys) and [update your environment variables](https://help.openai.com/en/articles/5112595-best-practices-for-api-key-safety).
3. For Python, `pip install groq`.
4. Read about the [Llama 3 8B model](https://console.groq.com/docs/models) downloaded from HuggingFace and invoke it.
```
from groq import Groq
LLM_NAME = "llama3-70b-8192"
groq_client = Groq(
api_key=os.environ.get("GROQ_API_KEY"),
)
start_time = time.time()
response = groq_client.chat.completions.create(
messages=[
{"role": "system", "content": SYSTEM_PROMPT,},
{"role": "user", "content": f"question: {SAMPLE_QUESTION}",}
],
model=LLM_NAME,
temperature=TEMPERATURE,
seed=RANDOM_SEED,
frequency_penalty=FREQUENCY_PENALTY,
top_p=TOP_P,
max_tokens=MAX_TOKENS,
)
llama3_groq_endpoints_time = time.time() - start_time
# Print the response.
pprint.pprint(response.choices[0].message.content.replace('\n', ' '))
print(f"llama3_groq_endpoints_time: {format(llama3_groq_endpoints_time, '.2f')} seconds")
```
The answer looks slightly more succinct, and the citation is perfect. The Llama 3 20B took ~1 second to invoke from Groq LPU endpoints, which is the fastest inference so far!
Note - to run Mixtral, follow all the same steps, just change the LLM_NAME to the name used by each Endpoint Platform for the Mixtral model.
## Run GPT-4o from OpenAI
To run the latest GPT-4o inference from OpenAI:
5. Get your OpenAI [API token](https://platform.openai.com/api-keys) and [update your environment variables](https://help.openai.com/en/articles/5112595-best-practices-for-api-key-safety).
6. Follow [instructions](https://github.com/openai/openai-cookbook/blob/main/examples/gpt4o/introduction_to_gpt4o.ipynb) for how to call the new model.
7. For Python, `pip install --upgrade openai --quiet`.
8. Read about the new [GPT-4o](https://openai.com/index/hello-gpt-4o/) model and invoke it.
```
import openai, pprint
from openai import OpenAI
LLM_NAME = "gpt-4o" # "gpt-3.5-turbo"
openai_client = OpenAI(
# This is the default and can be omitted
api_key=os.environ.get("OPENAI_API_KEY"),
)
start_time = time.time()
response = openai_client.chat.completions.create(
messages=[
{"role": "system", "content": SYSTEM_PROMPT,},
{"role": "user", "content": f"question: {SAMPLE_QUESTION}",}
],
model=LLM_NAME,
temperature=TEMPERATURE,
seed=RANDOM_SEED,
frequency_penalty=FREQUENCY_PENALTY,
top_p=TOP_P,
max_tokens=MAX_TOKENS,
)
chatgpt_4o_turbo_time = time.time() - start_time
# Print the question and answer along with grounding sources and citations.
print(f"Question: {SAMPLE_QUESTION}")
for i, choice in enumerate(response.choices, 1):
message = choice.message.content.replace('\n', '')
pprint.pprint(f"Answer: {message}")
print(f"chatgpt_4o_turbo_time: {format(chatgpt_4o_turbo_time, '.5f')}")
```
The new GPT-4o model looks good and it includes a grounding source citation. It took 2 seconds to run inference.
## Quick Answer Evaluation using Ragas
I explain in [this blog](https://zilliz.com/blog/rag-evaluation-using-ragas?utm_source=partner&utm_medium=referral&utm_campaign=2024_content-syn_top-content_devto) about how to use open source [Ragas](https://docs.ragas.io/en) to evaluate RAG systems. I’m only using one Q&A below. A more realistic evaluation would use ~20 questions.
```

ragas_llm = ragas.llms.llm_factory(model=LLM_NAME)
# Change the default embeddings to HuggingFace models.
EMB_NAME = "BAAI/bge-large-en-v1.5"
lc_embeddings = HuggingFaceEmbeddings(model_name=EMB_NAME)
ragas_emb = LangchainEmbeddingsWrapper(embeddings=lc_embeddings)
# Change each metric.
for metric in metrics:
globals()[metric].llm = ragas_llm
globals()[metric].embeddings = ragas_emb
# Execute the evaluation.
ragas_result, score = _eval_ragas.evaluate_ragas_model(
eval_df, eval_metrics, LLM_TO_EVALUATE,
CONTEXT_TO_EVALUATE, EVALUATE_WHAT)
# Display the results.
print(f"Using {eval_df.shape[0]} eval questions, Mean Score = {score}")
display(ragas_result.head())
```
Below is a table summarizing the results.

Nesse artigo vou falar um pouco sobre o Software Assurance Maturity Model - SAMM.
**OWASP**
Se essa é a primeira vez que escuta sobre a OWASP, convido-o a visitar o [site oficial](https://owasp.org/) e ler um [rápido artigo](https://dev.to/brmartin/eu-me-associei-a-owasp-3jb1) que escrevi há um tempo. Uma breve descrição seria:
A OWASP (Open Web Application Security Project) é uma fundação sem fins lucrativos dedicada ao aprimoramento da segurança de software. Por meio de projetos de código aberto colaborativos, uma vasta rede de comunidades locais globais, dezenas de milhares de membros e conferências educacionais de destaque, a OWASP Foundation se destaca como uma referência para desenvolvedores e profissionais de tecnologia que buscam proteger a web.
Portanto, a OWASP é conhecida por seus recursos, ferramentas e documentações, que são amplamente utilizados por profissionais de segurança da informação.
**Projeto SAMM**
Sobre o SAMM eu diria que o objetivo desse framework é entender o ponto de maturidade que a empresa avaliada se encontra no momento da entrevista e em qual ponto se deseja chegar, em termos de práticas de segurança. A partir desse entendimento, formular ou melhorar, e implementar uma estratégia com processos definidos adaptados ao apetite de riscos da Organização, que pode ser integrada ao Software Development Lifecycle (SDLC) existente.
Essa avaliação pode ser realizada de forma externa, através de um avaliador externo, ou através de uma autoavaliação realizada por uma equipe interna de segurança. A representação de todos os stakeholders é fundamental para o sucesso da atividade.
A estrutura do framework é dividida em 5 áreas de negócios com cada uma subdividida em três práticas de segurança: Governança (Estratégia e Métricas / Política e Conformidade / Educação e Orientação), Design ( Avaliação de Ameaça / Requisitos de Segurança / Arquitetura Segura), Implementação (Construção Segura / Implantação Segura / Gestão de Defeitos), Verificação (Avaliação de Arquitetura / Testes Orientados a Requisitos / Teste de Segurança), Operações (Gestão de Incidentes / Gestão Ambiental / Gestão Operacional).
Por fim, para cada prática de segurança, o SAMM define dois fluxos (stream) e três níveis de maturidade.
É importante destacar, que este modelo necessita de reavaliações contínuas. O monitoramento e ajustes das práticas é um ponto crucial para a melhoria contínua.
A planilha de Assessment Interview
Na primeira aba, estão os campos que deverão ser respondidos com base nas respostas dadas na entrevista.
A segunda aba apresenta o Scorecard. Facilitando a visualização da pontuação atingida e quais pontos necessitam de melhorias.
Na terceira aba encontramos o Roadmap, onde são descritas as ações e iniciativas a serem implementadas em cada fase do processo de maturidade, com base na avaliação inicial de maturidade (scorecard) e nos objetivos de segurança da organização.
E por fim, na última aba o Roadmap Chart é a representação visual do roadmap.
**Como busquei o entendimento**
Venho estudando muitos assuntos importantes para os profissionais de AppSec e o tema atual tem sido o SAMM. Dentro desse tópico, o conteúdo em vídeo (em português) do Eduardo B. Santos, MSc com teoria e demonstração prática como também o [curso oficial](https://owaspsamm.thinkific.com/courses/samm) (em inglês) do SAMM têm me ajudado bastante a consolidar conceitos que venho aplicando nas aulas do Luiz Henrique Custódio, onde tivemos a oportunidade de colocar a mão na massa e praticar em estudos de caso.
**Prática**
Durante o treinamento da Conviso, o Luiz Henrique Custódio nos desafiou a realizar um assessment utilizando o SAMM. O SAMM disponibiliza uma [planilha Assessment Interview](https://github.com/owaspsamm/core/releases/download/v2.0.8/SAMM_spreadsheet.xlsx), para ser utilizada como guia da entrevista de assessment. Estudos de caso e uma documentação extensa também estão disponíveis no site oficial do projeto OWASP SAMM.
Divididos em grupos, nossa tarefa era ler a documentação do estudo de caso e fazer perguntas pontuais ao cliente imaginário.
Esta atividade consistia em analisar uma empresa fictícia chamada CNVS BANKING, uma empresa especializada em serviços bancários com um quadro de 500 colaboradores, sendo 50 profissionais na equipe de TI.
Lembrando que não existem respostas certas ou erradas, fomos analisando o texto do estudo de caso e, na falta de informações, questionávamos o Luiz, nosso cliente imaginário, para maiores entendimentos.
Em situações reais, é aconselhável que se realize uma entrevista por área de negócio, mas com participantes plurais, ou seja, de áreas distintas que estejam envolvidas naquele ponto. Dessa forma, começamos não apenas a avaliar, mas entender a dor de cada um.
Embora a atividade de preencher a planilha seja muito simples, ela se torna desafiadora quando obter as informações do ambiente o mais fidedignas possíveis é algo muito complexo. Aqui não se buscam evidências.
O propósito principal não é auditar, mas gerar um autoconhecimento, buscando autonomia e aprendizado para elevação da maturidade do ambiente. Como consequência, cria-se uma cultura de proximidade entre equipes de desenvolvedores, de segurança e demais áreas envolvidas, onde uma enxerga a dor da outra, e o entendimento do propósito de se buscar uma elevação da maturidade.
Não trarei todas as avaliações de maturidade para não me estender muito, mas durante essa atividade alguns pontos me chamaram atenção, como o fato do time de DevOps afirmar que a modelagem de ameaças está em elaboração, porém o time de desenvolvimento não saber do que se trata. Notei uma falta de proximidade e comunicação entre as equipes, a qual levará a uma entrega que possivelmente criará atritos e ausência de engajamento. Assim, uma baixa pontuação foi atingida em Design.
Pelo lado positivo, as documentações de boas práticas de gerenciamento de secrets e o processo de priorização, realizado pelo analista de Appsec responsável pelo squad, garantindo que as particularidades de cada projeto sejam tratadas de acordo, no meu entendimento elevaram o nível de maturidade das práticas de segurança na Implementação.
Pude constatar após a atividade prática, a importância da realização das entrevistas e o uso do SAMM para a elevação da maturidade de segurança no desenvolvimento de software. Ele nos traz uma visão mais clara do ambiente de uma determinada empresa e ajuda no planejamento dos próximos passos para tornar uma aplicação mais segura possível.
A melhor maneira de entender o SAMM é começar a usá-lo.
**SAMMwise**
O readme do repositório do projeto assim o define:
“SAMMwise é um Web App de código aberto para calcular a pontuação de Maturidade de um indivíduo, empresa ou projeto usando o modelo SAMM. O aplicativo o orienta pela avaliação, permite que você salve e reutilize avaliações concluídas anteriormente e apresenta os resultados em um estilo semelhante à planilha.”
Seria então uma forma mais “moderna” de adoção do SAMM. Se desejar saber um pouco mais sobre a ferramenta, aconselho a leitura do artigo do Diego Pereira, [Utilizando SAMMWise](https://www.linkedin.com/pulse/utilizando-sammwise-diego-pereira-vwdff/).
**OpenCRE**
Nesse período de estudo tive a grata surpresa de descobrir o [OpenCRE](https://www.opencre.org/).
O projeto Open Source "OpenCRE" integra todos os padrões e diretrizes de segurança no nível de requisitos em um recurso unificado e harmonizado. Usar o OpenCRE com o SAMM oferece benefícios como acesso a recursos adicionais, comparação com outros padrões de segurança e eliminação de lacunas entre diferentes estruturas de segurança.
Para quem já está surfando a onda das IAs, eles oferecem também um [chatbot](https://www.opencre.org/chatbot).
Em um cenário onde a cibersegurança é vital, o SAMM é um guia valioso para proteger aplicações de forma eficaz.
Em meus estudos não encontrei a planilha em português, porém quem tiver ou souber da existência de uma tradução do material seria interessante compartilhar nos comentários. Afinal, esse é o propósito de comunidades como a OWASP, ambientes colaborativos em prol da evolução da segurança da web.
Aproveito para deixar como sugestão de leitura, uma série de artigos que explicam ponto a ponto a estrutura do framework SAMM.

1,921,699 | JavaScript30 - 8 Fun With HTML5 Canvas | Hello and welcome back to another exciting installment of my experience with Wes Bos's JavaScript30!... | 0 | 2024-07-12T21:37:57 | https://dev.to/virtualsobriety/javascript30-8-fun-with-html5-canvas-4pg3 | javascript, webdev, beginners, learning | Hello and welcome back to another exciting installment of my experience with Wes Bos's [JavaScript30!](https://javascript30.com/) This was probably the most fun I've had with the course so far! After starting this challenge I quickly decided to code along with Wes instead of trying to figure it out myself as I was very much out of my depth. I have never worked with Canvas before and there was plenty of syntax I did not understand. Could I possibly make my own version of an Etch-a-Sketch in a browser? Yeah sure, I could figure that out, but after seeing what he wanted as a finished product I took a step back.
So what was it that we did? Basically we did make an Etch-a-Sketch in HTML5 Canvas. The biggest difference was when you would draw the colors and size of the line would constantly change. I won't lie...how we managed to do this I still do not fully understand. But I do have a pretty decent idea.
As you can see from the picture above we ended up with an extremely colorful design, even if it isn't practical in the slightest. Basically, it seems Canvas is more or less "paint" but with more uses. I don't really see when I would be using it for any projects going forward but it was still a fun exercise as a whole.
Oh and learning about HSL was cool too! He took us to [mother effing HSL](https://mothereffinghsl.com/) so we could learn more about hues and colors. I would definitely recommend going to this site to see how you can mess with the color pallet. We used this by directly calling it in our code and incrementing it as we drew on the page.
```js
let isDrawing = false;
let lastX = 0;
let lastY = 0;
let hue = 0;
let direction = true;
function draw(e) {
if (!isDrawing) return;
console.log(e);
ctx.strokeStyle = `hsl(${hue}, 100%, 50%)`;
ctx.beginPath();
ctx.moveTo(lastX, lastY);
ctx.lineTo(e.offsetX, e.offsetY);
ctx.stroke();
[lastX, lastY] = [e.offsetX, e.offsetY];
hue++;
if (hue >= 360) {
hue = 0;
}
if (ctx.lineWidth >= 175 || ctx.lineWidth <= 1) {
direction = !direction;
}
if (direction) {
ctx.lineWidth++;
} else {
ctx.lineWidth--;
}
}
```
You can also see how we changed the size of the line itself by switching the direction of how it either increments or decrements based on the movement of the mouse. One line of the code still confuses me just based on how much is actually going on. That being ` if (ctx.lineWidth >= 175 || ctx.lineWidth <= 1) {
direction = !direction;`. This entire line is crazy to me. Mostly how its designed to flip on itself after getting to a certain amount. `||` still confuses me too and I'm not sold on how or why you would use a `!` in JavaScript. I will be looking into this more after I write this post, but if anyone could explain either of these concepts to me a bit more I would greatly appreciate it.
There was one other pretty big revelation I had during this challenge. That would be the use of semicolons while writing JavaScript. I really haven't done this before, even though it was suggested to me. I figured that just ending a line and continuing on a new line would be enough. I know that you have to use semicolons in CSS and that if you don't not anything will work the way you want it to. This was the first time I ever had an issue with JavaScript by not using them. By not having a semicolon after `ctx.stroke()` my code basically broke. Okay, it still worked, but definitely not as intended. For some reason it ran into the following line of code but the semicolon fixed that completely. Lesson learned.
All in all this was a fun challenge. I greatly enjoyed messing around with HTML5 Canvas even if I barely scratched the surface in regards to all that you can do with it. I drew on my browser for longer than I should have and also went back and messed with some of the values (i.e how the hue would increment, the max width of the lines, etc..) just to see what would happen. I probably couldn't recreate this on my own if I tried but I am still so fascinated as to what can be done with a few lines of JavaScript!
That's all for todays challenge. If you have the time I would highly suggest trying this one for yourself as it was far and away the most fun I have had so far! Be on the lookout for my next installment of the JavaScript30 with: 14 Must Know Dev Tools Tricks!

In this article, I discuss the code used to build the... | 0 | 2024-07-12T21:49:42 | https://dev.to/ramunarasinga/shadcn-uiui-codebase-analysis-how-does-shadcn-ui-cli-work-part-212-35h9 | shadcnui, nextjs, opensource, javascript | I wanted to find out how shadcn-ui CLI works. In this article, I discuss the code used to build the shadcn-ui/ui CLI.
In part 2.11, we looked at runInit function and how shadcn-ui/ui ensures directories provided in resolvedPaths in config exist.
The following operations are performed in runInit function:
1. Ensure all resolved paths directories exist.
2. Write tailwind config.
3. Write css file.
4. Write cn file.
5. Install dependencies.
Let’s understand how shadcn-ui/ui CLI writes to tailwind config in runInit function.
Write tailwind config
---------------------
After checking the directories exist, there are few more operations performed before writing tailwind config as shown in the below code.
This code is picked from [cli/src/commands/init.ts](https://github.com/shadcn-ui/ui/blob/main/packages/cli/src/commands/init.ts#L331C3-L356C4).
```js
const extension = config.tsx ? "ts" : "js"
const tailwindConfigExtension = path.extname(
config.resolvedPaths.tailwindConfig
)
let tailwindConfigTemplate: string
if (tailwindConfigExtension === ".ts") {
tailwindConfigTemplate = config.tailwind.cssVariables
? templates.TAILWIND\_CONFIG\_TS\_WITH\_VARIABLES
: templates.TAILWIND\_CONFIG\_TS
} else {
tailwindConfigTemplate = config.tailwind.cssVariables
? templates.TAILWIND\_CONFIG\_WITH\_VARIABLES
: templates.TAILWIND\_CONFIG
}
// Write tailwind config.
await fs.writeFile(
config.resolvedPaths.tailwindConfig,
template(tailwindConfigTemplate)({
extension,
prefix: config.tailwind.prefix,
}),
"utf8"
)
```
Let’s understand this code snippet
### Extension
```js
const extension = config.tsx ? "ts" : "js"
```
This extension is used in later parts of code that deal with writing cn file.
### tailwindConfigExtension
```js
const tailwindConfigExtension = path.extname(
config.resolvedPaths.tailwindConfig
)
```
The path.extname() method returns the extension of the path, from the last occurrence of the . (period) character to end of string in the last portion of the path. If there is no . in the last portion of the path, or if there are no . characters other than the first character of the basename of path (see path.basename()) , an empty string is returned.
```js
let tailwindConfigTemplate: string
if (tailwindConfigExtension === ".ts") {
tailwindConfigTemplate = config.tailwind.cssVariables
? templates.TAILWIND\_CONFIG\_TS\_WITH\_VARIABLES
: templates.TAILWIND\_CONFIG\_TS
} else {
tailwindConfigTemplate = config.tailwind.cssVariables
? templates.TAILWIND\_CONFIG\_WITH\_VARIABLES
: templates.TAILWIND\_CONFIG
}
```
Depending on the tailwindConfigExtension and config.tailwind.cssVariables, tailwindConfigTemplate is set to a value using [templates](https://github.com/shadcn-ui/ui/blob/main/packages/cli/src/utils/templates.ts). Templates is imported from [utils/templates](https://github.com/shadcn-ui/ui/blob/main/packages/cli/src/utils/templates.ts) and contains some variables initialised with values related to tailwind config
### Write to tailwind config file
```js
await fs.writeFile(
config.resolvedPaths.tailwindConfig,
template(tailwindConfigTemplate)({
extension,
prefix: config.tailwind.prefix,
}),
"utf8"
)
```
[template](https://lodash.com/docs#template) used here in the above snippet is different from utils/templates. Different how? this template is imported from [lodash.template](https://lodash.com/docs#template)
Read more about [lodash.template](https://lodash.com/docs#template)
An example using lodash.template:
```js
// Use the "interpolate" delimiter to create a compiled template.
var compiled = \_.template('hello <%= user %>!');
compiled({ 'user': 'fred' });
// => 'hello fred!'
```
This explains why there is %extension% in utils/templates.ts
It gets replaced with w/e is passed. Interesting…
Conclusion:
-----------
After checking the directories exist (explained in the part 2.11), there are few more operations performed before writing tailwind config as shown in the below code.
```js
const extension = config.tsx ? "ts" : "js"
const tailwindConfigExtension = path.extname(
config.resolvedPaths.tailwindConfig
)
let tailwindConfigTemplate: string
if (tailwindConfigExtension === ".ts") {
tailwindConfigTemplate = config.tailwind.cssVariables
? templates.TAILWIND\_CONFIG\_TS\_WITH\_VARIABLES
: templates.TAILWIND\_CONFIG\_TS
} else {
tailwindConfigTemplate = config.tailwind.cssVariables
? templates.TAILWIND\_CONFIG\_WITH\_VARIABLES
: templates.TAILWIND\_CONFIG
}
// Write tailwind config.
await fs.writeFile(
config.resolvedPaths.tailwindConfig,
template(tailwindConfigTemplate)({
extension,
prefix: config.tailwind.prefix,
}),
"utf8"
)
```
extension — This extension is used in later parts of code that deal with writing cn file.
tailwindConfigExtension — The path.extname() method returns the extension of the path, from the last occurrence of the . (period) character to end of string in the last portion of the path.
Depending on the tailwindConfigExtension and config.tailwind.cssVariables, tailwindConfigTemplate is set to a value using [templates](https://github.com/shadcn-ui/ui/blob/main/packages/cli/src/utils/templates.ts). Templates is imported from [utils/templates](https://github.com/shadcn-ui/ui/blob/main/packages/cli/src/utils/templates.ts) and contains some variables initialised with values related to tailwind config
Write to tailwind config file — using fs.writeFile, tailwindConfig is updated but there is a catch. template from lodash.template is used to perform some replacements before writing to the file.
An example usage of lodash.template from the docs:
```js
// Use the "interpolate" delimiter to create a compiled template.
var compiled = \_.template('hello <%= user %>!');
compiled({ 'user': 'fred' });
// => 'hello fred!'

These frameworks streamline workflows and help create stunning, responsive designs. Among the plethora of options available, Tailwind CSS has emerged as a game-changer. It offers a unique and highly customizable approach to styling web applications.
In this post, we will delve into what makes Tailwind CSS stand out, explore its core features, and show how you can leverage it to build modern, beautiful, and maintainable UIs.
What is Tailwind CSS?
Tailwind CSS is a utility-first CSS framework that provides low-level utility classes to build custom designs directly in your markup. Unlike traditional CSS frameworks that come with pre-designed components, Tailwind CSS gives you the freedom to craft your own components without imposing any design restrictions.
Key Features of Tailwind CSS
1. Highly Customizable: Tailwind CSS provides a powerful configuration file (tailwind.config.js) that allows you to customize the default theme, extend utility classes, and even define your own design tokens. This flexibility ensures that your design language can be precisely tailored to your project's requirements.
2. Utility-First Approach: Tailwind CSS offers a comprehensive set of utility classes for controlling every aspect of your design, from layout and spacing to typography and color. This approach promotes consistency and reusability while keeping your CSS file size minimal.
3. Responsive Design: With built-in responsive utilities, Tailwind CSS makes it effortless to create responsive layouts. You can apply different styles based on breakpoints, ensuring your application looks great on all screen sizes.
4. Excellent Documentation: Tailwind CSS boasts thorough and well-organized documentation, complete with examples, tutorials, and a searchable API. Whether you're a beginner or an experienced developer, the documentation will guide you through the framework's capabilities.
Getting Started with Tailwind CSS
To start using Tailwind CSS in your project, follow these simple steps:
1. Install Tailwind CSS: You can install Tailwind CSS via npm or yarn:
```
npm install tailwindcss
```
2. Create a Configuration File: Generate a configuration file to customize your Tailwind setup:
```
npx tailwindcss init
```
3. Integrate Tailwind CSS: Add Tailwind's directives to your CSS file:
```
@tailwind base;
@tailwind components;
@tailwind utilities;`
```
4. Build Your CSS: Use Tailwind's CLI to generate your CSS:
```
npx tailwindcss build src/tailwind.css -o dist/tailwind.css
```
5. Use Utility Classes: Start using Tailwind's utility classes in your HTML to style your components:
```
<div class="bg-blue-500 text-white p-4 rounded-lg shadow-lg">
Hello, It's Tailwind!
</div>
```
conclusion
Tailwind CSS has revolutionized the way developers approach styling in web development. Its utility-first philosophy, extensive customization options, and focus on performance make it an invaluable tool for building modern, responsive web applications. By adopting Tailwind CSS, you can streamline your workflow, maintain consistency, and unlock limitless design possibilities. Embrace the power of Tailwind CSS and elevate your web development game to new heights! | irohomolola |

There are a couple... | 0 | 2024-07-12T21:53:37 | https://dev.to/kemiowoyele1/basic-css-selectors-4182 | CSS selectors are used to target specific HTML elements and apply styles to them. There are a couple of ways we can be specific about the element we intend to select. In this chapter, we are going to focus on four basic selection methods.
## 1. Universal selector (*)
Universal selector is used to target all elements in the page at once. This selector is usually useful in cases of some basic formatting. Most common use of the universal selector is to remove default margins and paddings.
Example
```
* {
margin: 0;
padding: 0;
box-sizing: border-box;
}
```
## 2. Selecting by element name
With this approach, all elements of the one named by the selector will be styled accordingly. This will only exclude those selected differently as we will see in future examples.
Code sample:
HTML
```
<h3>this is heading 1</h3>
<p>this is paragraph 1</p>
<p>this is paragraph 2</p>
<p>this is paragraph 3</p>
<h3>this is heading 2</h3>
<p>this is paragraph 4</p>
<p>this is paragraph 5</p>
```
CSS
```
body{
background: lightgray;
}
h3{
color: blue;
}
p{
color: red;
}
```
Result
## 3. Selecting by id
An id is a unique identifier that sets apart an element from the other elements. Ideally, there should be only one element with the same id on a page. There could be many elements with the id attribute, but not more than one should bear the same name. Otherwise there will be nothing unique about the id. So to style an element with an id, use the id attribute to give it a name in HTML, then use the # symbol before that name, when selecting in CSS.
HTML
```
<body>
<h3 >this is heading 1</h3>
<p>this is paragraph 1</p>
<p >this is paragraph 2</p>
<p>this is paragraph 3</p>
<h3>this is heading 2</h3>
<p id="unique">this is paragraph 4</p>
<p>this is paragraph 5</p>
</body>
```
CSS
```
#unique{
color: green;
}
body{
background: lightgray;
}
h3{
color: blue;
}
p{
color: red;
}
```
Result
## 4. Selecting by class
Class works kind of similar to id, but in the case of class, there could be more than one element with the same class name. To style an element with a class name, use the class attribute to give it a name in HTML, then use the . symbol before that name, when selecting in CSS.
Code sample
HTML
```
<h3 >this is heading 1</h3>
<p class="pink">this is paragraph 1</p>
<p class="pink" >this is paragraph 2</p>
<p class="pink">this is paragraph 3</p>
<h3>this is heading 2</h3>
<p id="unique">this is paragraph 4</p>
<p>this is paragraph 5</p>
```
CSS
```
.pink{
background: pink;
}
body{
background: lightgray;
}
h3{
color: blue;
}
p{
color: red;
}
```
Result
## Conclusion
Each selector type has its own purpose and usage. Understanding how to use each selector is crucial for effective HTML styling and layout control. Proper use of selectors can help create visually appealing and well-structured web pages, making it easier for users to interact with and understand the content presented.

Suddenly, you're faced with a puzzle - how do you efficiently allocate these instances across your subnets without turning your VPC into a digital traffic jam 😵?
Ahh total mess!! Let's understand the problem statement clearly.
Imagine you're the conductor of a grand cloud orchestra. You've got a VPC with more than two subnets, and you're tasked with deploying a variety of servers, including those sneaky auto-scaling groups that grow and shrink on a whim. The question that keeps you up at night: "How can I ensure each instance finds its perfect subnet home, automatically 🤔?"
Sure, AWS offers auto-allocation of IP addresses within a CIDR block, but when you're dealing with a complex VPC architecture, you need something smarter. Something that can look at the big picture and make decisions that keep your network balanced and efficient.
Ta-daa, here enters The Smart Subnet Allocator 🤓.
After much head-scratching and coffee-fueled brainstorming, I stumbled upon an elegant solution. Here's the secret sauce:
1. **Subnet Reconnaissance**: First, we scout out all available subnets in our target VPC. It's like taking inventory of all possible homes for our instances.
2. **IP Usage Analytics**: We then put on our detective hats and calculate how many IPs are being used in each subnet. This gives us a clear picture of which neighborhoods are bustling and which are quiet.
3. **The Great Subnet Sort**: Armed with this information, we sort our subnets from least crowded to most crowded. It's like arranging your closet from emptiest shelf to fullest.
4. **Round-Robin Magic**: Finally, we assign our instances to subnets in a round-robin fashion, starting with the least crowded subnet. It's like dealing cards, ensuring everyone gets a fair shot at the best spots.
This approach ensures that we're always placing new instances in the subnets with the most room to breathe, automatically balancing our network load and making the most efficient use of our VPC real estate.
By implementing this logic in Terraform, we can automate this entire process, making our infrastructure not just code, but smart code. It's like having a tiny, efficient robot organizing your cloud resources for optimal performance.
We'll next dive into the Terraform code that makes this happen. We'll show you how to implement this smart subnet allocation strategy, turning your VPC from a chaotic city into a well-planned metropolis of cloud resources.
```tf
terraform {
required_providers {
aws = {
version = ">= 2.7.0"
source = "hashicorp/aws"
}
}
}
```
We first configured Terraform and required providers. For our use case we took AWS as the cloud provider
```tf
# Fetch VPC details
data "aws_vpc" "vpc" {
filter {
name = var.vpc_name
values = var.vpc_values
}
state = "available"
}
# Get all subnet IDs inside the VPC
data "aws_subnet_ids" "subnets" {
vpc_id = var.vpc_id
tags = {
Type = "my-vpc"
}
}
# Fetch details for all available subnets
data "aws_subnet" "available_subnets" {
for_each = data.aws_subnet_ids.subnets.ids
id = each.value
}
# Get instance allocation details for each subnet
data "aws_instances" "instances_in_subnets" {
for_each = data.aws_subnet.available_subnets
filter {
name = "subnet-id"
values = [each.value.id]
}
}
```
For the next, we defined our data section in order to get the subnet details from our VPC.
```tf
locals {
# Calculate available IP count for each subnet
subnet_counts = {
for subnet in data.aws_subnet.available_subnets : subnet.id =>
tonumber(split("/", subnet.cidr_block)[1]) - length(data.aws_instances.instances_in_subnets[subnet.id].ids)
}
# Sort subnets based on available IP count (ascending order)
sorted_subnet_counts = sort([
for subnet_id, count in local.subnet_counts :
{ subnet_id = subnet_id, count = count }
])
# Reverse the sorted list to get descending order
sorted_subnet_counts_desc = reverse(local.sorted_subnet_counts)
}
```
This code snippet encapsulates the core logic of our solution:
1. The _subnet_counts_ map calculates the number of available IPs in each
subnet, addressing points 1 and 2 of our solution.
2. _sorted_subnet_counts_ transforms this information into a sorted list,
implementing point 3.
3. Finally, _sorted_subnet_counts_desc_ reverses the list, preparing us
for the round-robin allocation described in point 4.
Now that we have our sorted list of subnets, let's look at how we can use it to deploy multiple instances with smart subnet allocation.
```tf
# Considering simplest approach to deploy multiple instances
variable "instance_count" {
type = number
default = 50
}
# Create EC2 instances with dynamic subnet allocation
resource "aws_instance" "instance" {
count = var.instance_count
instance_type = "t2.micro"
subnet_id = local.sorted_subnet_counts_desc[count.index % length(local.sorted_subnet_counts_desc)].subnet_id
tags = {
Name = "instance-${count.index + 1}"
}
# Other configuration...
}
```
This code demonstrates the practical application of our subnet allocation strategy:
1. We define a variable _instance_count_ to specify how many instances we
want to deploy.
2. The aws_instance resource uses Terraform's count parameter to create
multiple instances.
3. The _subnet_id_ assignment is where the magic happens. We use the
modulo operator (%) to cycle through our sorted subnet list in a
round-robin fashion, implementing the fourth point of our solution.
4. Each instance is tagged with a unique name for easy identification.
This approach ensures that our instances are evenly distributed across the available subnets, starting with those that have the most available IPs. It's a simple yet effective way to maintain balance in your VPC as you scale your infrastructure.
Let's not forget, in the world of cloud infrastructure, a little automation goes a long way 😋.
Happy terraforming 🤗! | suvankit |
