# Python 中的砖块排序算法[易于实现]
> 原文：<https://www.askpython.com/python/examples/brick-sort-algorithm>
在本教程中，我们将学习如何实现砖块排序算法，以便对数组中的元素进行排序。这在编码界是未知的，但学习一种新的排序技术没有坏处。
在用 python 编程语言实现 brick sort 之前，让我们先了解一下什么是 brick sort。
***也读作:[在 Python 中插入排序](https://www.askpython.com/python/examples/insertion-sort-in-python)***
* * *
## 砖块排序算法简介
**砖块排序**，又称**奇偶排序**，是**泡泡排序**的修改版本。排序算法分为两个阶段，即**奇数阶段和偶数阶段**。通过确保在每次迭代中执行偶数和奇数阶段，控制将一直运行，直到对数组进行排序。
现在你可能会问这些奇数和偶数阶段是什么意思？当控件执行奇数阶段时，我们将只对奇数索引处的元素进行排序。在事件阶段的执行过程中，以类似的模式，控件将只对偶数索引处的元素进行排序。
* * *
## 砖块排序算法实现
为了实现砖块排序，我们将遵循一些步骤，下面也将提到。
* 声明**砖块排序函数**来执行排序，并取一个变量到**在奇数和偶数阶段**之间切换。
* 创建一个变量 **isSort** ，初始值为 0。此变量的目的是跟踪当前阶段。
* 运行 while 循环进行迭代，直到 isSort 等于 1。
1. 创建一个内部 for 循环来对奇数条目进行排序。
2. 类似地，创建另一个内部 for 循环来对偶数条目进行排序。
* 一旦排序完成，我们**返回结果**。
* * *
## 在 Python 中实现砖块排序
让我们直接进入 Python 中的块排序算法的实现，并确保我们可以获得预期的输出。
```py
def brickSort(array, n):
isSort = 0
while isSort == 0:
isSort = 1
for i in range(1, n-1, 2):
if array[i] > array[i+1]:
array[i], array[i+1] = array[i+1], array[i]
isSort = 0
for i in range(0, n-1, 2):
if array[i] > array[i+1]:
array[i], array[i+1] = array[i+1], array[i]
isSort = 0
return
array = [31, 76, 18, 2, 90, -6, 0, 45, -3]
n = len(array)
print("Array input by user is: ", end="")
for i in range(0, n):
print(array[i], end =" ")
brickSort(array, n);
print("\nArray after brick sorting is: ", end="")
for i in range(0, n):
print(array[i], end =" ")
```
上面提到的代码如下所示。您可以看到数组排序成功。
```py
Array input by user is: 31 76 18 2 90 -6 0 45 -3
Array after brick sorting is: -6 -3 0 2 18 31 45 76 90
```
* * *
## 结论
我希望今天你学到了一种新的排序算法。虽然要求不多，但是口袋里有一些额外的知识总是好的！
感谢您的阅读！快乐学习！😇

# Consigna 🎯
Utilizando los conceptos aprendidos en la unidad 13- Bases de datos relacionales (SQL DDL), resolver el siguiente ejercicio:
1. Instalar SQL Server Express
2. Instalar SQL Server Management Studio
3. Crear una base de datos
4. Crear 3 tablas: Alumno, Materia y Cursa.
- Alumno deberá tener los siguientes campos: Legajo, nombre, apellido y fecha de nacimiento
- Materia deberá tener los siguientes campos:
Código y descripción.
- Finalmente, la tabla Cursa deberá tener
los siguientes campos: legajo y código de materia.
- Para las tablas se deberá definir la clave primaria. También deben crearse las claves foráneas.
5. Insertar 5 tuplas en cada una de las tablas
6. Exportar el script de creación de la base de datos con sus datos.
7. Borrar la base creada.
8. Restaurar la base de datos desde el script generado en el punto 6.
# Notas 📄
- Se dispone el script "Cursadas.sql" el cuál se utilizó para crear y poblar la base de datos en un principio.
- Se dispone el script "Cursadas - Auto generado.sql" el cuál se generó a través del gestor de base de datos de manera automática, y al ejecutarlo nos genera el mismo resultado que el primer script. |

<h3>Continuous</h3>
<p>Continuous data is a type of numerical data that refers to the unspecified number of possible measurements between two realistic points.</p>
<p>These numbers are not always clean and tidy like those in discrete data, as they're usually collected from precise measurements. Over time, measuring a particular subject allows us to create a defined range, where we can reasonably expect to collect more data.</p>
<p>Continuous data is all about accuracy. Variables in these data sets often carry decimal points, with the number to the right stretched out as far as possible. This level of detail is paramount for scientists, doctors, and manufacturers, to name a few.</p>
<p>Some examples of continuous data include:</p>
<ul>
<li>The weight of new born babies</li>
<li>The daily wind speed</li>
<li>The temperature of a freezer</li>
</ul>
<p>When you think of experiments or studies involving constant measurements, they're likely to be continuous variables to some extent. If you have a number like “2.86290” anywhere on a spreadsheet, it's not a number you could have quickly arrived at yourself — think measurement devices like stopwatches, scales, thermometers, and the like.</p>
<h3>Discrete, Categorical</h3>
<p>Discrete data is a numerical type of data that includes whole, concrete numbers with specific and fixed data values determined by counting. Continuous data includes complex numbers and varying data values that are measured over a specific time interval.</p>
<p>Some examples of discrete data one might gather:</p>
<ul>
<li>The number of customers who bought different items</li>
<li>The number of computers in each department</li>
<li>The number of items you buy at the grocery store each week</li>
</ul>
<p>Discrete data can also be qualitative. The nationality you select on a form is a piece of discrete data. The nationalities of everyone in your workplace, when grouped, can be valuable information in evaluating your hiring practices.</p>

'desc_1': """
<h3>Relationships</h3>
<p>Relationships in probability and statistics can generally be one of three things: deterministic, random, or statistical. Relationship has been divided by 3 types of relationship.</p>
<ul>
<li><b>Deterministic Relationship</b></li>
<p>A deterministic relationship involves an exact relationship between two variables.</p>
<li><b>Random Relationship</b></li>
<p>A random relationship is a bit of a misnomer because there is no relationship between the variables. However, random processes may make it seem like there is a relationship.</p>
<li><b>Statistical Relationship</b></li>
<p>A statistical relationship is a mixture of deterministic and random relationships.</p>
</ul>
<h3>Differences</h3>
<p>
Statistical difference refers to significant differences between groups of objects or people. Scientists calculate this difference to determine whether the data from an experiment is reliable before drawing conclusions and publishing results. When studying the relationship between two variables, scientists use the chi-square calculation method. When comparing two groups, scientists use the t-distribution method
</p>
<ul>
<li><b>Chi-Square Method</b></li>
<p>Create a data table with a row for each possible result and a column for each group involved in the experiment. For example, if you are trying to answer the question of whether picture flash cards or word flash cards better help children pass a vocabulary test, you would create a table with three columns and two rows. The first column would be marked, "Passed Test?" and two rows beneath the heading would be marked "Yes" and "No." The next column would be labelled "Picture Cards" and the final column would be labelled "Word Cards."</p>
<li><b>T-Test Method</b></li>
<p>Make a data table showing the number of observations for each of two groups, the mean of the results for each group, the standard deviation from each mean and the variance for each mean. Subtract the group two mean from the group one mean. Divide each variance by the number of observations minus 1. For example, if one group had a variance of 2186753 and 425 observations, you would divide 2186753 by 424. Take the square root of each result. Divide each result by the corresponding result from Step 2. Calculate the degrees of freedom by totalling the number of observations for both groups and dividing by 2.</p>
</ul>
""",
'desc_11': """
<h3>Independent variable?</h3>
<p><i>The two main variables in an experiment are the independent and dependent variable.</i></p>
<p>An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment.</p>
<p><i>What's the Difference Between Homogeneous and Heterogeneous?</i></p>
<p>The dependent variable is 'dependent' on the independent variable. As the experimenter changes the independent variable, the effect on the dependent variable is observed and recorded.</p>
<p><i>Independent and Dependent Variable Example.</i></p>
<p>For example, a scientist wants to see if the brightness of light has any effect on a moth being attracted to the light. The brightness of the light is controlled by the scientist. This would be the independent variable. How the moth reacts to the different light levels (distance to light source) would be the dependent variable.</p>
<p><i>How to Tell the Variables Apart.</i></p>
<p>The independent and dependent variables may be viewed in terms of cause and effect. If the independent variable is changed, then an effect is seen in the dependent variable. Remember, the values of both variables may change in an experiment and are recorded. The difference is that the value of the independent variable is controlled by the experimenter, while the value of the dependent variable only changes in response to the independent variable.</p>
""",
'desc_12': """
<h3>Means</h3>
<p>In statistics, the mean summarizes an entire dataset with a single number representing the data's center point or typical value. It is also known as the arithmetic average, and it is one of several measures of central tendency.</p>
<p>Ideally, the mean indicates the region where most values in a distribution fall. Statisticians refer to it as the central location of a distribution. You can think of it as the tendency of data to cluster around a middle value.</p>
<h3>Tests for Equal Variances</h3>
<p>Use a test for equal variances to test the equality of variances between populations or factor levels. Many statistical procedures, such as analysis of variance (ANOVA) and regression, assume that although different samples can come from populations with different means, they have the same variance.</p>
<p>Because the susceptibility of different procedures to unequal variances varies greatly, so does the need to do a test for equal variances. For example, ANOVA inferences are only slightly affected by inequality of variance if the model contains only fixed factors and has equal or almost equal sample sizes. Alternatively, ANOVA models with random effects and/or unequal sample sizes could be substantially affected.</p>
<p>For example, you plan to do an ANOVA testing the length of time callers are put on hold where the main fixed factor is the calling center. You use the ANOVA general linear model (GLM) because you have unequal sample sizes. Because this unbalanced condition increases the susceptibility to unequal variances, you decide to test the assumption of equal variances. If the resulting p-value is greater than adequate choices of alpha, you fail to reject the null hypothesis of the variances being equal. You can feel confident that the assumption of equal variances is being met.</p>
<p>For tests for equal variances, the hypotheses are:</p>
<ul>
<li>H0: All variances are equal</li>
<li>H1: Not all variances are equal</li>
</ul>

<h3>Correlation Analysis</h3>
<p>Correlation Analysis is statistical method that is used to discover if there is a relationship between two variables/datasets, and how strong that relationship may be.</p>
<p>In terms of market research this means that, correlation analysis is used to analyse quantitative data gathered from research methods such as surveys and polls, to identify whether there is any significant connections, patterns, or trends between the two.</p>
<p>Essentially, correlation analysis is used for spotting patterns within datasets. A positive correlation result means that both variables increase in relation to each other, while a negative correlation means that as one variable decreases, the other increases.</p>
<h3>Parametric</h3>
<p><i>(Pearson's Coefficient)</i> Where the data must be handled in relation to the parameters of populations or probability distributions. Typically used with quantitative data already set out within said parameters.</p>
<p>Advantage of Parametric:</p>
<ul>
<li>Parametric tests can provide trustworthy results with distributions that are skewed and nonnormal</li>
<li>Parametric tests can provide trustworthy results when the groups have different amounts of variability</li>
<li>Parametric tests have greater statistical power</li>
</ul>
<h3>Nonparametric</h3>
<p><i>(Spearman's Rank)</i> Where no assumptions can be made about the probability distribution. Typically used with qualitative data but can be used with quantitative data if Spearman's Rank proves inadequate.</p>
<p>Advantage of Nonparametric:</p>
<ul>
<li>Nonparametric tests assess the median which can be better for some study areas</li>
<li>Nonparametric tests are valid when our sample size is small, and your data are potentially nonnormal</li>
<li>Nonparametric tests can analyse ordinal data, ranked data, and outliers</li>
</ul>
<p>If we have a small dataset, the distribution can be a deciding factor. However, in many cases, this issue is not critical because of the following:</p>
<ul>
<li>Parametric analyses can analyse nonnormal distributions for many datasets.</li>
<li>Nonparametric analyses have other firm assumptions that can be harder to meet.</li>
</ul>
<p>The answer is often contingent upon whether the mean or median is a better measure of central tendency for the distribution of your data.</p>
<ul>
<li>If the mean is a better measure and you have a sufficiently large sample size, a parametric test usually is the better, more powerful choice.</li>
<li>If the median is a better measure, consider a nonparametric test regardless of your sample size.</li>

<h3>Regression Analysis</h3>
<p>
Regression analysis is a set of statistical methods used for the estimation of
relationships between a dependent variable and one or more independent variables.
It can be utilized to assess the strength of the relationship
between variables and for modeling the future relationship between them.
Regression analysis includes several variations, such as linear, multiple linear, and nonlinear.
The most common models are simple linear and multiple linear.
Nonlinear regression analysis is commonly used for more complicated data sets
in which the dependent and independent variables show a nonlinear relationship.

<h3>Pearson's R</h3>
<p>
In Statistics, the Pearson's Correlation Coefficient is also referred to as Pearson's r,
the Pearson product-moment correlation coefficient (PPMCC), or bivariate correlation.
It is a statistic that measures the linear correlation between two variables.
Like all correlations, it also has a numerical value that lies between -1.0 and +1.0.
Pearson's correlation coefficient is the covariance of the two variables divided by
the product of their standard deviations. The form of the definition involves a
"product moment", that is, the mean (the first moment about the origin) of
the product of the mean-adjusted random variables; hence the modifier product-moment in the name.
Pearson's Correlation Coefficient is named after Karl Pearson.
He formulated the correlation coefficient from a related idea by Francis Galton in the 1880s.

<h3>Fmax Test</h3>
<p>
The Fmax test (also called Hartley's Fmax) is a test for
homogenity of variance. In other words, the spread (variance)
of your data should be similar across groups or levels.
Compared to Levene's test, Hartley's test is fairly simple
to figure out by hand. An assumption of the Fmax test is that
there are an equal number of participants in each group.
</p>
<h3>Brown & Smythe's Test</h3>
<p>
The Brown-Forsythe test is a statistical test for the equality
of group variances based on performing an Analysis of Variance
(ANOVA) on a transformation of the response variable.
When a one-way ANOVA is performed, samples are assumed to
have been drawn from distributions with equal variance.
If this assumption is not valid, the resulting F-test is invalid.
The Brown-Forsythe test statistic is the F statistic resulting
from an ordinary one-way analysis of variance on the absolute
deviations of groups/treatments data from their individual medians.
</p>
""",
'desc_122': """
<h3>Two groups</h3>
<p>
Independent sample t-test is a statistical technique that is
used to analyze the mean comparison of two independent groups.
In independent samples t-test, when we take two samples from
the same population, then the mean of the two samples may be
identical. But when samples are taken from two different
populations, then the mean of the sample may differ. In this
case, it is used to draw conclusions about the means of two
populations, and used to tell whether or not they are similar.
</p>
<h3>More than two groups</h3>
<p>
For a comparison of more than two group means the one-way analysis
of variance (ANOVA) is the appropriate method instead of the t test.
As the ANOVA is based on the same assumption with the t test,
the interest of ANOVA is on the locations of the distributions
represented by means too. Then why is the method comparing several
means the 'analysis of variance', rather than 'analysis of means'
themselves? It is because that the relative location of the several
group means can be more conveniently identified by variance among
the group means than comparing many group means directly when
number of means are large.

# The Bechdel Test
https://fivethirtyeight.com/features/the-dollar-and-cents-case-against-hollywoods-exclusion-of-women/
The [Bechdel test](https://bechdeltest.com) is a way to assess how women are depicted in Hollywood movies. In order for a movie to pass the test:
1. It has to have at least two [named] women in it
2. Who talk to each other
3. About something besides a man
There is a nice article and analysis you can find here https://fivethirtyeight.com/features/the-dollar-and-cents-case-against-hollywoods-exclusion-of-women/
We have a sample of 1394 movies and we want to fit a model to predict whether a film passes the test or not.
```{r read_data}
bechdel <- read_csv(here::here("data", "bechdel.csv")) %>%
mutate(test = factor(test))
glimpse(bechdel)
```
How many films fail/pass the test, both as a number and as a %?
```{r}
# Assuming the column with pass/fail information is 'test' and pass is represented as 'Pass'
pass_fail_counts <- bechdel %>%
count(test)
# To calculate the percentage
pass_fail_counts <- pass_fail_counts %>%
mutate(percent = n/sum(n) * 100)
# Display the counts and percentages
pass_fail_counts
```
## Movie scores
```{r}
ggplot(data = bechdel, aes(
x = metascore,
y = imdb_rating,
colour = test
)) +
geom_point(alpha = .3, size = 3) +
scale_colour_manual(values = c("tomato", "olivedrab")) +
labs(
x = "Metacritic score",
y = "IMDB rating",
colour = "Bechdel test"
) +
theme_light()
```
# Split the data
```{r}
# **Split the data**
set.seed(123)
data_split <- initial_split(bechdel, # updated data
prop = 0.8,
strata = test)
bechdel_train <- training(data_split)
bechdel_test <- testing(data_split)
```
Check the counts and % (proportions) of the `test` variable in each set.
```{r}
# For the training set
train_counts <- bechdel_train %>%
count(test) %>%
mutate(percent = n/sum(n) * 100)
# For the test set
test_counts <- bechdel_test %>%
count(test) %>%
mutate(percent = n/sum(n) * 100)
# Display the counts and percentages
train_counts
test_counts

```{r}
# Perform summary statistics for each of the features in the training data
summary(bechdel_train)
```
Grouped Summary Statistics:
```{r}
grouped_data <- bechdel_train %>% group_by(test) %>% summarise(mean_budget = mean(budget_2013), mean_domgross = mean(domgross_2013), mean_intgross = mean(intgross_2013), mean_metascore = mean(metascore), mean_imdb_rating = mean(imdb_rating))
print(grouped_data)
```
mean_budget: On average, films that fail the Bechdel test have a higher budget (approximately 6.85 in 2013 dollars) compared to films that pass the test (approximately 4.67 in 2013 dollars). This could suggest that films with larger budgets are less likely to have substantial female roles or female-centric narratives.
mean_domgross: Films that fail the Bechdel test also, on average, earn more at the domestic box office (around 10.65 in 2013 dollars) compared to films that pass the test (around 8.09 in 2013 dollars). This might indicate that films with less focus on female characters or narratives have historically performed better in domestic markets, although the difference is not substantial.
mean_intgross: Similar to domestic gross, films that fail the Bechdel test tend to earn more in international box office (approximately 23.25 in 2013 dollars) compared to films that pass the test (approximately 17.40 in 2013 dollars). This suggests that, like domestic markets, international audiences have also tended to favor films that do not pass the Bechdel test.
mean_metascore: Films that fail the Bechdel test have a slightly higher average Metascore (around 59.14) compared to films that pass the test (around 57.80). This might indicate that critics, on average, slightly favor films that fail the Bechdel test. However, the difference is minimal, indicating that whether a film passes or fails the Bechdel test does not significantly impact its critical reception.
mean_imdb_rating: Similarly, films that fail the Bechdel test have a slightly higher average IMDb rating (around 6.92) compared to films that pass the test (around 6.61). This might suggest that viewers have slightly favored films that fail the Bechdel test, although, like Metascore, the difference is not significant.
Proportions of Rated Groups:
```{r}
bechdel_train %>%
group_by(rated) %>%
summarise(n = n(), prop = n() / nrow(bechdel_train)) %>%
ggplot(aes(x = reorder(rated, -prop), y = prop)) +
geom_col() +
labs(x = "Rated", y = "Proportion")
```
This bar graph shows how data is distributed across the different rated groups within the dataset. There are many R and PG rated films, with very few NC-17 films. This makes sense as NC-17 are very rare.
## Any outliers?
```{r}
bechdel %>%
select(test, budget_2013, domgross_2013, intgross_2013, imdb_rating, metascore) %>%
pivot_longer(cols = 2:6,
names_to = "feature",
values_to = "value") %>%
ggplot()+
aes(x=test, y = value, fill = test)+
coord_flip()+
geom_boxplot()+
facet_wrap(~feature, scales = "free")+
theme_bw()+
theme(legend.position = "none")+
labs(x=NULL,y = NULL)
```
For budget, domestic gross and international gross, there are multiple outliers on the upper end but not the lower. This makes sense as although most films range within the 7 figures for budget, there are some "blockbusters" that have far higher budgets, and therefore generate far more revenue. Franchise films such as the Avengers or Fast & Furious fall under this category.
The rating measures, including the IMDB and Metascore rating, are far more consistent apart from a smaller number of outliers on the lower end, particularly for IMDB. This is likely due to reviews on either end of the spectrum being more common, with harsh reviews tending the be on the far lower end. The reason as the why the IMDB score contains more negative outliers is due to it being based on both critic and audience reviews (which tend to be harsher), whilst Metascore only contains critic scores.
## Scatterplot - Correlation Matrix
Write a paragraph discussing the output of the following
```{r, warning=FALSE, message=FALSE}
bechdel %>%
select(test, budget_2013, domgross_2013, intgross_2013, imdb_rating, metascore)%>%
ggpairs(aes(colour=test), alpha=0.2)+
theme_bw()
```
The correlation between imdb_rating and metascore for Fail group is 0.739, and for Pass it's 0.743. These are strong positive correlations, suggesting that movies with higher IMDB ratings also tend to have higher Metascore, regardless of whether they pass or fail the test. The correlation is almost the same for both groups, suggesting the relationship between IMDB rating and Metascore is similarly strong for both movies that pass and fail the Bechdel test.
The strong correlation between domestic gross and international gross for both Fail (0.927) and Pass (0.956) groups suggests that films that perform well domestically also tend to perform well internationally, regardless of whether they pass or fail the Bechdel test. This could imply that factors influencing domestic success also translate to international markets, such as genre, star power, or the film's overall quality. This relationship is slightly stronger for films that pass the Bechdel test.
On the other hand, the low correlation between the budget and both IMDb rating and Metascore suggests that a higher budget does not necessarily result in better critical ratings. The quality of a film, as assessed by both viewers (IMDb rating) and critics (Metascore), does not seem to be directly related to its production budget, whether it passes or fails the Bechdel test. This could be because film quality is determined by many factors beyond budget, such as script, direction, performances, etc. Therefore, spending more money on a film's production does not guarantee it will be better received by audiences or critics.
## Categorical variables
Write a paragraph discussing the output of the following
```{r}
bechdel %>%
group_by(genre, test) %>%
summarise(n = n()) %>%
mutate(prop = n/sum(n))
bechdel %>%
group_by(rated, test) %>%
summarise(n = n()) %>%
mutate(prop = n/sum(n))
```
Looking at the ratings, it seems that films rated G have approximately a 61.54% chance of failing the Bechdel test, and a 38.46% chance of passing. Films rated NC-17 have a much higher chance of failing the Bechdel test (83.33%) and a very low chance of passing (16.67%). PG-rated films are more evenly distributed with a failure rate of 56.10% and a pass rate of 43.90%. This is similar for PG-13 rated films, which have a failure rate of 52.90% and a pass rate of 47.10%. R-rated films have a higher chance of failing the Bechdel test (56.75%) than passing it (43.25%).
These findings suggest that films with more restricted ratings (NC-17 and R) are more likely to fail the Bechdel test. Conversely, films with more general audience ratings (G, PG, and PG-13) are somewhat more balanced, although they still fail the test more often than not. This could be due to a variety of factors, including differences in storytelling and character focus based on target audience demographics, or perhaps more mature or complex themes and narratives in R and NC-17 films that don't lend themselves as readily to passing the Bechdel test.
# Train first models. `test ~ metascore + imdb_rating`
```{r}
lr_mod <- logistic_reg() %>%
set_engine(engine = "glm") %>%
set_mode("classification")
lr_mod
tree_mod <- decision_tree() %>%
set_engine(engine = "C5.0") %>%
set_mode("classification")
tree_mod
```
```{r}
lr_fit <- lr_mod %>% # parsnip model
fit(test ~ metascore + imdb_rating, # a formula
data = bechdel_train # dataframe
)
tree_fit <- tree_mod %>% # parsnip model
fit(test ~ metascore + imdb_rating, # a formula
data = bechdel_train # dataframe
)
```
## Logistic regression
```{r}
lr_fit %>%
broom::tidy()
lr_preds <- lr_fit %>%
augment(new_data = bechdel_train) %>%
mutate(.pred_match = if_else(test == .pred_class, 1, 0))
```
### Confusion matrix
```{r}
lr_preds %>%
conf_mat(truth = test, estimate = .pred_class) %>%
autoplot(type = "heatmap")
```
This model only returns a 58% accuracy rate, and therefore is not very reliable.
## Decision Tree
```{r}
tree_preds <- tree_fit %>%
augment(new_data = bechdel) %>%
mutate(.pred_match = if_else(test == .pred_class, 1, 0))
```
```{r}
tree_preds %>%
conf_mat(truth = test, estimate = .pred_class) %>%
autoplot(type = "heatmap")
```
This model has a very similar, but albeit slightly smaller accuracy rate, at just under 58%.
## Draw the decision tree
```{r}
draw_tree <-
rpart::rpart(
test ~ metascore + imdb_rating,
data = bechdel_train, # uses data that contains both birth weight and `low`
control = rpart::rpart.control(maxdepth = 5, cp = 0, minsplit = 10)
) %>%
partykit::as.party()
plot(draw_tree)
```
# Cross Validation
Run the code below. What does it return?
```{r}
set.seed(123)
bechdel_folds <- vfold_cv(data = bechdel_train,
v = 10,
strata = test)
bechdel_folds
```
This code creates a 10-fold cross-validation plan with the bechdel_train data, with the folds being created in a stratified manner according to the test variable. This means that each fold will have roughly the same proportion of pass/fail as the original data. The output will be a tibble with two columns: .folds and .id. Each row in the .folds column is a list-column that contains the split objects for the resamples.
## `fit_resamples()`
Trains and tests a resampled model.
```{r}
lr_fit <- lr_mod %>%
fit_resamples(
test ~ metascore + imdb_rating,
resamples = bechdel_folds
)
tree_fit <- tree_mod %>%
fit_resamples(
test ~ metascore + imdb_rating,
resamples = bechdel_folds
)
```
## `collect_metrics()`
Unnest the metrics column from a tidymodels `fit_resamples()`
```{r}
collect_metrics(lr_fit)
collect_metrics(tree_fit)
```
```{r}
tree_preds <- tree_mod %>%
fit_resamples(
test ~ metascore + imdb_rating,
resamples = bechdel_folds,
control = control_resamples(save_pred = TRUE) #<<
)
# What does the data for ROC look like?
tree_preds %>%
collect_predictions() %>%
roc_curve(truth = test, .pred_Fail)
# Draw the ROC
tree_preds %>%
collect_predictions() %>%
roc_curve(truth = test, .pred_Fail) %>%
autoplot()
```
# Build a better training set with `recipes`
## Preprocessing options
- Encode categorical predictors
- Center and scale variables
- Handle class imbalance
- Impute missing data
- Perform dimensionality reduction
- ... ...
## To build a recipe
1. Start the `recipe()`
1. Define the variables involved
1. Describe **prep**rocessing [step-by-step]
## Collapse Some Categorical Levels
Do we have any `genre` with few observations? Assign genres that have less than 3% to a new category 'Other'
```{r}
#| echo = FALSE
bechdel %>%
count(genre) %>%
mutate(genre = fct_reorder(genre, n)) %>%
ggplot(aes(x = genre,
y = n)) +
geom_col(alpha = .8) +
coord_flip() +
labs(x = NULL) +
geom_hline(yintercept = (nrow(bechdel_train)*.03), lty = 3)+
theme_light()
```
```{r}
movie_rec <-
recipe(test ~ .,
data = bechdel_train) %>%
# Genres with less than 5% will be in a catewgory 'Other'
step_other(genre, threshold = .03)
```
## Before recipe
```{r}
#| echo = FALSE
bechdel_train %>%
count(genre, sort = TRUE)
```
## After recipe
```{r}
movie_rec %>%
prep() %>%
bake(new_data = bechdel_train) %>%
count(genre, sort = TRUE)
```
## `step_dummy()`
Converts nominal data into numeric dummy variables
```{r}
#| results = "hide"
movie_rec <- recipe(test ~ ., data = bechdel) %>%
step_other(genre, threshold = .03) %>%
step_dummy(all_nominal_predictors())
movie_rec
```
## Let's think about the modelling
What if there were no films with `rated` NC-17 in the training data?
- Will the model have a coefficient for rated NC-17?
No, the model will not have a coefficient for rated NC-17 if there were no films with this rating in the training data. Coefficients in a model represent the relationship between the predictors in the training data and the outcome variable. If a category does not exist in the training data, there is no way to estimate its effect, hence, it will not have a coefficient.
- What will happen if the test data includes a film with rated NC-17?
If the test data includes a film with rated NC-17 and the training data does not have this category, the model will not be able to make an accurate prediction for this film. This is because the model has not learned any relationship between films with rated NC-17 and the outcome variable. The prediction may fail, or the model may treat this category as if it were the reference category or as missing data.
## `step_novel()`
Adds a catch-all level to a factor for any new values not encountered in model training, which lets R intelligently predict new levels in the test set.
```{r}
movie_rec <- recipe(test ~ ., data = bechdel) %>%
step_other(genre, threshold = .03) %>%
step_novel(all_nominal_predictors) %>% # Use *before* `step_dummy()` so new level is dummified
step_dummy(all_nominal_predictors())
```
## `step_zv()`
Intelligently handles zero variance variables (variables that contain only a single value)
```{r}
movie_rec <- recipe(test ~ ., data = bechdel) %>%
step_other(genre, threshold = .03) %>%
step_novel(all_nominal(), -all_outcomes()) %>% # Use *before* `step_dummy()` so new level is dummified
step_dummy(all_nominal(), -all_outcomes()) %>%
step_zv(all_numeric(), -all_outcomes())
```
## `step_normalize()`
Centers then scales numeric variable (mean = 0, sd = 1)
```{r}
movie_rec <- recipe(test ~ ., data = bechdel) %>%
step_other(genre, threshold = .03) %>%
step_novel(all_nominal(), -all_outcomes()) %>% # Use *before* `step_dummy()` so new level is dummified
step_dummy(all_nominal(), -all_outcomes()) %>%
step_zv(all_numeric(), -all_outcomes()) %>%
step_normalize(all_numeric())
```
## `step_corr()`
Removes highly correlated variables
```{r}
movie_rec <- recipe(test ~ ., data = bechdel) %>%
step_other(genre, threshold = .03) %>%
step_novel(all_nominal(), -all_outcomes()) %>% # Use *before* `step_dummy()` so new level is dummified
step_dummy(all_nominal(), -all_outcomes()) %>%
step_zv(all_numeric(), -all_outcomes()) %>%
step_normalize(all_numeric()) %>%
step_corr(all_predictors(), threshold = 0.75, method = "spearman")
movie_rec
```
# Define different models to fit

#Logistic Regression:
Accuracy: 0.4321429. This means that the logistic regression model correctly predicted the class of the target variable approximately 43.21% of the time. This is generally considered low accuracy.
Kappa: -0.1052632. Kappa is an evaluation metric that takes into account the possibility of a correct prediction by chance. It's usually between 0 (random classification) and 1 (perfect classification). A negative value means the classifier is doing worse than random chance.
#Decision Tree:
Accuracy: 0.5892857. The decision tree model correctly predicted the class about 58.93% of the time. This is better than the logistic regression model.
Kappa: 0.1445271. The model's predictions are not random, but the value is still low, indicating a limited level of agreement.
#Random Forest:
Accuracy: 0.5785714. The random forest model had an accuracy of approximately 57.86%, which is slightly lower than the decision tree.
Kappa: 0.1158683. The kappa value is lower than that of the decision tree, suggesting that the model's predictions are not as reliable.
#Boosted Tree:
Accuracy: 0.5785714. The boosted tree model matched the random forest in accuracy, predicting correctly about 57.86% of the time.
Kappa: 0.1339450. Its kappa value is slightly higher than the random forest's, suggesting a better level of agreement.
#K-NN (K-Nearest Neighbors):
Accuracy: 0.5535714. The K-NN model predicted correctly about 55.36% of the time.
Kappa: 0.0000000. The kappa value of 0 indicates that this model's predictions are as good as random.
In summary, out of these models, the Decision Tree performed the best based on both accuracy and kappa metrics. Furthermore, these are not the only metrics to assess model performance, and the choice of metrics should be based on the specific use-case and problem at hand.

# Rubric
13/13: Problem set is 100% completed. Every question was attempted and answered, and most answers are correct. Code is well-documented (both self-documented and with additional comments as necessary). Used tidyverse, instead of base R. Graphs and tables are properly labelled. Analysis is clear and easy to follow, either because graphs are labeled clearly or you've written additional text to describe how you interpret the output. Multiple Github commits. Work is exceptional. I will not assign these often.
8/13: Problem set is 60--80% complete and most answers are correct. This is the expected level of performance. Solid effort. Hits all the elements. No clear mistakes. Easy to follow (both the code and the output). A few Github commits.
5/13: Problem set is less than 60% complete and/or most answers are incorrect. This indicates that you need to improve next time. I will hopefully not assign these often. Displays minimal effort. Doesn't complete all components. Code is poorly written and not documented. Uses the same type of plot for each graph, or doesn't use plots appropriate for the variables being analyzed. No Github commits. |

* There are n stairs, and a person is allowed to jump next stair, skip one stair or skip two stairs. So there are

* Brute Force Solution:
* Like the Fibonacci problem, the runtime of this algorithm is exponential (roughly 0(3^n)), since each call
* branches out to three more calls.
* <p>
* Time Complexity: O(3^n).
* The time complexity of the above solution is exponential, a close upper bound will be O(3^n). From each state,
* 3 recursive function are called. So the upperbound for n states is O(3^n).
* Space Complexity: O(N).

# C function and Assmebly:
# Preparing for using C functions in assembly program:
------------------------------------------------------
- Each C function starts with pushing RBX, RSP, RBP, RSI, RDI to stack. Due to their spedial importance these five registers are sometimes
half jokingly called the "Sacred registers" of C.
- C functions return value in RAX register. If the return value is more than 64 bits, its returned in RDX:RAX format. Floating point return
values are returned in floating point stack. Other data structure such as array, structure, object etc are returned as pointer to these data
structures, so they are just 64-bit value.
- Function parameters are pushed to stack in reversed order. So to call a function MyFunc(foo, bar, bas), stack have to be prepared like this:
push bas
push bar
push foo
call MyFunc
- A function doesn't pop the parameters from the stack. So calling procedure must remove them after calling the function. This can be done by
popping or modifying the RSP with appropriate offset.
# glibc stack frame: |_______________________________|
-------------------- | NULL = End of Argument list |
---------------------------------
The stack | - - - |
| _ _ _ | ---------------------------------
| _ _ _ | +24 | Arg 3 |
----------------------------------- ---------------------------------
| RBP+40: | - - - | +16 | Arg 2 |
----------------------------------- ---------------------------------
| RBP+32: |Ptr. to Env. var. tbl. | +8 | Arg 1 |
----------------------------------- ---------------------------------
| RBP+24: | Ptr. to Arg. tbl. | -------------------------> | Arg(0): Invocation text |
----------------------------------- ---------------------------------
| RBP+16: | Argument count |
-----------------------------------
| RBP+08: | Return Address |
-----------------------------------
| RBP+00: | RBP |
-----------------------------------
| RBP-08: | RBX |
-----------------------------------
| RBP-16: | RSI |
-----------------------------------
| RBP-24: | RDI |
-----------------------------------
| RBP-32: | - - - |
-----------------------------------
Thus from a C program, or a assembly program using C functions, command line arguments can be accessed by referencing RBP+24 twice. |

# One extra dollar in our budget

#One extra dollar in our budget
Interaction model:

# One extra dollar in our budget
Now, let's interpret some coefficients:

- If `\(Bechdel = 1\)`, then:
`$$Revenue = (\beta_0 + \beta_1) + (\beta_3 + \beta_6)Budget + \beta_4IMDB + \beta_5 MetaScore + \varepsilon$$`

# Models with interactions
- You include the interaction between two (or more) covariates:
`$$\widehat{Price} = \beta_0 + \hat{\beta}_1 Rating + \hat{\beta}_2 Miles + \hat{\beta}_3 Luxury + \hat{\beta}_4 Year + \hat{\beta}_5 Luxury \times Year$$`
--
- `\(\hat{\beta}_3\)` and `\(\hat{\beta}_4\)` are considered the **.darkorange[main effects]** (no interaction)

- The coefficient you are interested in is `\(\hat{\beta}_5\)`:
- Difference in the **.darkorange[price change]** for one additional year between **.darkorange[luxury vs non-luxury cars]**, holding other variables constant.

# Now it's your turn

Args:
checkpoint: path to notochord model checkpoint.
player_config: mapping from MIDI channels to MIDI instruments controlled
by the player.
noto_config: mapping from MIDI channels to MIDI instruments controlled
by notochord. Both indexed from 1.
instruments should be different from the player instruments.
channels should be different unless different ports are used.
MIDI channels and General MIDI instruments are indexed from 1.
initial_mute: start Notochord muted so it won't play with input.
initial_query: query Notochord immediately so it plays even without input.
midi_in: MIDI ports for player input.
default is to use all input ports.
can be comma-separated list of ports.
midi_out: MIDI ports for Notochord output.
default is to use only virtual 'From iipyper' port.
can be comma-separated list of ports.
thru: if True, copy incoming MIDI to output ports.
only makes sense if input and output ports are different.
send_pc: if True, send MIDI program change messages to set the General MIDI
instrument on each channel according to player_config and noto_config.
useful when using a General MIDI synthesizer like fluidsynth.
dump_midi: if True, print all incoming MIDI for debugging purposes
balance_sample: choose instruments which have played less recently
ensures that all configured instruments will play.
n_recent: number of recent note-on events to consider for above
n_margin: amount of 'slack' in the balance_sample calculation
max_note_len: time in seconds after which to force-release sustained
notochord notes.
max_time: maximum time in seconds between predicted events.
default is the Notochord model's maximum (usually 10 seconds).
nominal_time: if True, feed Notochord with its own predicted times
instead of the actual elapsed time.
May make Notochord more likely to play chords.
osc_port: optional. if supplied, listen for OSC to set controls
osc_host: hostname or IP of OSC sender.
leave this as empty string to get all traffic on the port
use_tui: run textual UI.
predict_player: forecasted next events can be for player.
generally should be true, use balance_sample to force Notochord to
play.
auto_query=True, # query notochord whenever it is unmuted and there is no pending event. generally should be True unless debugging.

<desc>Us caldrà instal·lar el Flash per poder visualitzar correctament alguns llocs web, aquells que mostrin vídeos i pàgines web interactives.</desc>
<include xmlns="http://www.w3.org/2001/XInclude" href="legal.xml"/>

<title>Instal·leu el connector Flash</title>
<p>El Flash és un <em>connector</em> per al vostre navegador que us permet veure vídeos i fer ús de pàgines web interactives en alguns llocs webs. Tot i que cada vegada l'HTML5, que és una solució més moderna, és més present, encara hi ha alguns llocs webs que no funcionen sense Flash.</p>
<p>Si no teniu instal·lat el Flash, molt probablement veureu un missatge informant-vos que el necessiteu quan visiteu algun lloc web. El Flash està disponible en descàrrega gratuïta (però no és codi obert) per a la majoria de navegadors web.</p>
<note style="warning">
<p>Adobe va anunciar que deixarien d'actualitzar i distribuir el Flash Player a finals de 2020. Per aquesta raó, per motius de seguretat, no hauríeu d'utilitzar el connector de Flash passat 2020.</p>
</note>
<p>Hi ha dues classes de connectors disponibles:</p>
<list>
<item>
<p><em>NPAPI</em> per al <app>Firefox</app> i d'altres navegadors web basats en Gecko</p>
</item>
<item>
<p><em>PPAPI</em> per a <app>Chromium</app> i altres navegadors web basat en Blink, incloent-hi l'<app>Opera</app> i el <app>Vivaldi</app></p>

</list>
<note>
<p>El navegador <app>Google Chrome</app> ja incorpora el Flash i no cal instal·lar-hi cap connector.</p>

So, What we are?
An open-source web console to manage your seatunnel-script, and would push them to any scheduling-system easily.
Click it if your want to know more about our design. 👉🏻[Design](https://github.com/apache/seatunnel/issues/1947)
## How to start
Notice: Some details please refer to the docs/QuickStart.md
### 1 Preparing the Apache SeaTunnel environment
Because SeaTunnel Web uses the SeaTunnel Java Client to submit jobs, running SeaTunnel Web requires preparing a SeaTunnel Zeta Engine service first.
Based on the usage requirements of SeaTunnel Zeta Engine, the SeaTunnel Client node that submits the job must have the same operating system and installation directory structure as the SeaTunnel Server node that runs the job. Therefore, if you want to run SeaTunnel Web in IDEA, you must install and run a SeaTunnel Zeta Engine Server on the same machine as the IDEA.
Don't worry, the next steps will tell you how to correctly install SeaTunnel Zeta Engine Server in different situations.
### 2 Run SeaTunnel Web in IDEA
If you want to deploy and run SeaTunnel Web, Please turn to [3 Run SeaTunnel Web In Server](#3 Run SeaTunnel Web In Server)
#### 2.1 Install SeaTunnel Zeta Engine Server
You have two ways to get the SeaTunnel installer package. Build from source code or download from the SeaTunnel website.
**The SeaTunnel version used here is only for writing this document to show you the process used, and does not necessarily represent the correct version. SeaTunnel Web and SeaTunnel Engine have strict version dependencies, and you can confirm the specific version mapping through xxx. Now only support build SeaTunnel Web and Seatunnel Zeta Engine in local, Because it is necessary to ensure that the seatunnel-api in SeaTunnel Web and the version in SeaTunnel Zeta Engine are the same.**
##### 2.1.1 Build from source code and deploy
* Get the source package from https://seatunnel.apache.org/download or https://github.com/apache/seatunnel.git
* Build installer package use maven command `./mvnw -U -T 1C clean install -DskipTests -D"maven.test.skip"=true -D"maven.javadoc.skip"=true -D"checkstyle.skip"=true -D"license.skipAddThirdParty" `
* After building, it is necessary to set an environment variable `ST_WEB_BASEDIR_PATH` to represent the location of the data source shade package. A custom class loader will be used to load the data source shade package based on this. For example: `ST_WEB_BASEDIR_PATH=/seatunnel-web-dist/target/apache-seatunnel-web-1.0.0-SNAPSHOT/`
* Then you can get the installer package in `${Your_code_dir}/seatunnel-dist/target`, For example:`apache-seatunnel-2.3.3-SNAPSHOT-bin.tar.gz`
* Run `tar -zxvf apache-seatunnel-2.3.3-SNAPSHOT-bin.tar.gz` to unzip the installer package.
* Run `cd apache-seatunnel-2.3.3-SNAPSHOT & sh bin/seatunnel-cluster.sh -d` to run the SeaTunnel Zeta Engine Server.
* Please confirm that port 5801 is being monitored by the SeaTunnelServer process.
##### 2.1.2 Download installer package and deploy
The other way to install SeaTunnel Zeta Engine Server is download the installer package from https://seatunnel.apache.org/download and deploy.
* Download and install connector plugin(Some third-party dependency packages will also be automatically downloaded and installed during this process, such as hadoop jar). You can get the step from https://seatunnel.apache.org/docs/2.3.2/start-v2/locally/deployment.
* Run `cd apache-seatunnel-2.3.2 & sh bin/seatunnel-cluster.sh -d` to run the SeaTunnel Zeta Engine Server.
#### 2.2 Init database
1. Edit `seatunnel-server/seatunnel-app/src/main/resources/script/seatunnel_server_env.sh` file, Complete the installed database address, port, username, and password. Here is an example:
```
export HOSTNAME="localhost"
export PORT="3306"
export USERNAME="root"
export PASSWORD="123456"
```
2. Run init shell `sh seatunnel-server/seatunnel-app/src/main/resources/script/init_sql.sh` If there are no errors during operation, it indicates successful initialization.
#### 2.3 Build the project
```shell
sh build.sh code
```
#### 2.4 Config application and Run SeaTunnel Web Backend Server
1. Edit `seatunnel-server/seatunnel-app/src/main/resources/application.yml` Fill in the database connection information
2. Copy `apache-seatunnel-2.3.3-SNAPSHOT/connectors/plugin-mapping.properties` file to `seatunnel-web/seatunnel-server/seatunnel-app/src/main/resources` dir.
3. Run `seatunnel-server/seatunnel-app/src/main/java/org/apache/seatunnel/app/SeatunnelApplication.java` If there are no errors reported, the seatunnel web backend service is successfully started. Notice that, you must set `-DSEATUNNEL_HOME=${your_seatunnel_install_path}` like this:
Because the data source plugin is dynamically loaded, it is necessary to set relevant environment variables:
#### 2.3 Run SeaTunnel Web Front End
```
cd seatunnel-ui
npm install
npm run dev
```
If there are no issues with the operation, the following information will be displayed:
```
➜ Local: http://127.0.0.1:5173/
➜ Network: use --host to expose
➜ press h to show help
```
Accessing in a browser http://127.0.0.1:5173/login Okay, the default username and password are admin/admin.
### 3 Run SeaTunnel Web In Server
To run SeaTunnel Web on the server, you need to first have a SeaTunnel Zeta Engine Server environment. If you do not already have one, you can refer to the following steps for deployment.
#### 3.1 Deploy SeaTunnel Zeta Engine Server In Server Node
You have two ways to get the SeaTunnel installer package. Build from source code or download from the SeaTunnel website.
**The SeaTunnel version used here is only for writing this document to show you the process used, and does not necessarily represent the correct version. SeaTunnel Web and SeaTunnel Engine have strict version dependencies, and you can confirm the specific version mapping through xxx**
##### 3.1.1 Build from source code
* Get the source package from https://seatunnel.apache.org/download or https://github.com/apache/seatunnel.git
* Build installer package use maven command `./mvnw -U -T 1C clean install -DskipTests -D"maven.test.skip"=true -D"maven.javadoc.skip"=true -D"checkstyle.skip"=true -D"license.skipAddThirdParty" `
* Then you can get the installer package in `${Your_code_dir}/seatunnel-dist/target`, For example:`apache-seatunnel-2.3.3-SNAPSHOT-bin.tar.gz`
##### 3.1.2 Download installer package
The other way to get SeaTunnel Zeta Engine Server installer package is download the installer package from https://seatunnel.apache.org/download and install plugins online.
* Download and install connector plugin(Some third-party dependency packages will also be automatically downloaded and installed during this process, such as hadoop jar). You can get the step from https://seatunnel.apache.org/docs/2.3.2/start-v2/locally/deployment.
* After completing the previous step, you will receive an installation package that can be used to install SeaTunnel Zeta Engine Server on the server. Run `tar -zcvf apache-seatunnel-2.3.3-SNAPSHOT-bin.tar.gz apache-seatunnel-2.3.3-SNAPSHOT`
##### 3.1.3 Deploy SeaTunnel Zeta Server
After 3.1.1 or 3.1.2 you can get an installer package `apache-seatunnel-2.3.3-SNAPSHOT-bin.tar.gz`, Then you can copy it to you server node and deploy reference https://seatunnel.apache.org/docs/seatunnel-engine/deployment.
##### 3.1.4 Deploy SeaTunnel Zeta Client In SeaTunnel Web Run Node
If you use SeaTunnel Web, you need deploy a SeaTunnel Zeta Client in the SeaTunnel Web run Node. **If you run SeaTunnel Zeta Server and SeaTunnel Web in same node, you can skip this step**.
* Copy `apache-seatunnel-2.3.3-SNAPSHOT-bin.tar.gz` to the SeaTunnel Web node and unzip it **in the same path of SeaTunnel Zeta Server node**.
* Set `SEATUNNEL_HOME` to environment variable like SeaTunnel Zeta Server node.
* Config `hazelcast-client.yaml` reference https://seatunnel.apache.org/docs/seatunnel-engine/deployment#6-config-seatunnel-engine-client
* Run `$SEATUNNEL_HOME/bin/seatunnel.sh --config $SEATUNNEL_HOME/config/v2.batch.config.template`, If this job run finished, it indicates successful client deployment.
#### 3.2 Build SeaTunnel Web Install Package From Code
```
cd seatunnel-web
sh build.sh code
```
Then you can find the installer package in dir `seatunnel-web/seatunnel-web-dist/target/apache-seatunnel-web-${project.version}.tar.gz`.
#### 3.3 Install
Copy the `apache-seatunnel-web-${project.version}.tar.gz` to your server node and unzip it.
```shell
tar -zxvf apache-seatunnel-web-${project.version}.tar.gz
```
#### 3.4 Init database
1. Edit `apache-seatunnel-web-${project.version}/script/seatunnel_server_env.sh` file, Complete the installed database address, port, username, and password. Here is an example:
```
export HOSTNAME="localhost"
export PORT="3306"
export USERNAME="root"
export PASSWORD="123456"
```
2. Run init shell `sh apache-seatunnel-web-${project.version}/script/init_sql.sh` If there are no errors during operation, it indicates successful initialization.
#### 3.5 Config application and Run SeaTunnel Web Backend Server
* Edit `apache-seatunnel-web-${project.version}/conf/application.yml` Fill in the database connection information and DS interface related information in the file.
* Copy `$SEATUNNEL_HOME/config/hazelcast-client.yaml` to `apache-seatunnel-web-${project.version}/conf/`
* Copy `apache-seatunnel-2.3.3-SNAPSHOT/connectors/plugin-mapping.properties` file to `apache-seatunnel-web-${project.version}/conf/` dir.
#### 3.6 Start SeaTunnel Web
```shell
cd apache-seatunnel-web-${project.version}
sh bin/seatunnel-backend-daemon.sh start
```
Accessing in a browser http://127.0.0.1:8801/ui/ Okay, the default username and password are admin/admin.

</p>
</header>
<section>
<h3 id="titulo2">CONCEITO DE DESIGN RESPONSIVO</h3>
<ol>
<li>
<h3>Definição e objetivos.</h3>
</li>
<p>
Uma das técnicas fundamentais do design responsivo é a criação de layouts flexíveis e fluidos. Essa
abordagem permite que os elementos da interface se ajustem automaticamente às diferentes dimensões da
tela, proporcionando uma experiência de usuário consistente e agradável em uma variedade de
dispositivos. Os layouts flexíveis e fluidos são a base sobre a qual muitos outros aspectos do design
responsivo são construídos. Vamos explorar em mais detalhes essa técnica:O design responsivo é uma
abordagem no desenvolvimento web que visa criar interfaces digitais que se adaptem de maneira fluida e
eficaz a uma ampla variedade de dispositivos e tamanhos de tela, incluindo desktops, laptops, tablets e
smartphones. Em outras palavras, um design responsivo permite que um site ou aplicativo se ajuste
automaticamente às dimensões da tela do dispositivo em que está sendo visualizado, garantindo uma
experiência de usuário consistente e agradável.
</p>
<p>
Objetivos do Design Responsivo: Consistência da Experiência do Usuário; Acessibilidade; Melhoria na Taxa
de Rejeição; SEO Aprimorado; Economia de Tempo e Recursos e Acompanhamento das Tendências Tecnológicas.
</p>
<li>
<h3>Necessidade de adaptação a dispositivos diversos.</h3>
</li>
<p>
Uma das técnicas fundamentais do design responsivo é a criação de layouts flexíveis e fluidos. Essa
abordagem permite que os elementos da interface se ajustem automaticamente às diferentes dimensões da
tela, proporcionando uma experiência de usuário consistente e agradável em uma variedade de
dispositivos. Os layouts flexíveis e fluidos são a base sobre a qual muitos outros aspectos do design
responsivo são construídos. Vamos explorar em mais detalhes essa técnica:O conceito de design responsivo
emerge da necessidade fundamental de proporcionar uma experiência de usuário consistente e otimizada em
uma ampla gama de dispositivos e tamanhos de tela. Com a proliferação de dispositivos móveis, tablets,
laptops, desktops e até mesmo dispositivos vestíveis, a criação de interfaces que se adaptem de forma
inteligente e harmoniosa se tornou uma prioridade para os desenvolvedores e designers de hoje.
</p>
<tag><img src="design-responsivo.png"></tag>
<li>
<h3>Importância na era mobile-first.</h3>
</li>
<p>
O conceito de design responsivo se tornou ainda mais relevante na era "mobile-first", que é uma
abordagem estratégica em que o design e desenvolvimento de uma interface começam pelo foco nos
dispositivos móveis, priorizando a experiência do usuário nesses dispositivos e expandindo para telas
maiores. Essa abordagem reflete a crescente importância dos dispositivos móveis na forma como as pessoas
acessam informações, serviços e interagem com a web.

<h3 id="titulo3">TÉCNICAS DE DESIGN RESPONSIVO</h3>
<ol>
<li>
<h3>Layouts flexíveis e fluídos. </h3>
</li>
<p>
Uma das técnicas fundamentais do design responsivo é a criação de layouts flexíveis e fluidos. Essa
abordagem permite que os elementos da interface se ajustem automaticamente às diferentes dimensões da
tela, proporcionando uma experiência de usuário consistente e agradável em uma variedade de
dispositivos. Os layouts flexíveis e fluidos são a base sobre a qual muitos outros aspectos do design
responsivo são construídos. Vamos explorar em mais detalhes essa técnica:
</p>
<p>
Layouts flexíveis e fluidos referem-se ao uso de unidades de medida relativas e proporções flexíveis em
vez de medidas fixas (como pixels) para dimensionar elementos da interface. Isso permite que os
elementos se estendam e contraiam de acordo com o tamanho da tela do dispositivo, criando uma adaptação
suave e sem quebras.
</p>
<li>
<h3>Uso de unidades relativas (em, rem).</h3>
</li>
<p>
No design responsivo, o uso de unidades de medida relativas desempenha um papel fundamental na criação
de layouts flexíveis e adaptáveis a diferentes tamanhos de tela. Duas das unidades de medida relativas
mais comuns são "em" e "rem". Essas unidades permitem que os elementos da interface se dimensionem de
acordo com o contexto, proporcionando uma adaptação suave e consistente em dispositivos diversos. Vamos
explorar mais detalhadamente o uso dessas unidades relativas: Unidade "em" (em): A unidade "em" (em) é
relativa ao tamanho da fonte do elemento pai. Isso significa que 1 "em" é igual ao tamanho da fonte
definido para o elemento pai. Por exemplo, se o tamanho da fonte do elemento pai for 16 pixels, 1em será
igual a 16 pixels.
</p>
<li>
<h3>Media queries: breakpoints e adaptação condicional.</h3>
</li>
<p>
Media queries são uma técnica crucial no design responsivo, permitindo que os desenvolvedores e
designers criem layouts que se adaptem de forma específica a diferentes tamanhos de tela e dispositivos.
Os breakpoints em media queries indicam os pontos em que um design deve ser adaptado para acomodar
diferentes contextos de exibição. A adaptação condicional ocorre dentro desses breakpoints, permitindo
ajustes precisos na apresentação do conteúdo. Vamos explorar mais detalhadamente essas técnicas:
</p>
<ul>
<li>
Breakpoints: são pontos de interrupção definidos nas media queries, indicando quando um layout deve
ser adaptado para tamanhos de tela específicos. Eles são definidos em larguras de tela específicas e
são usados para modificar a apresentação do conteúdo, como reorganizar elementos, ajustar tamanhos
de fonte e alterar a disposição dos componentes.
</li>
<li>
Adaptação Condicional: Dentro de um breakpoint, ocorre a adaptação condicional, que envolve a
aplicação de regras CSS específicas para otimizar o layout para o tamanho de tela em questão. Isso
pode incluir reorganização de elementos, ocultação de conteúdo menos relevante, ajuste de tamanhos
de fonte e outros ajustes para garantir uma experiência de usuário ideal.
</li>
</ul>
<br>
<tag><img src="media.png"></tag>
<li>
<h3>Imagens responsivas e otimização.</h3>
</li>
<p>
A otimização de imagens e a implementação de imagens responsivas são aspectos cruciais do design
responsivo, uma vez que as imagens frequentemente compõem grande parte do conteúdo visual de um site ou
aplicativo. Garantir que as imagens se adaptem bem a diferentes dispositivos e resoluções é essencial
para proporcionar uma experiência de usuário consistente e de alto desempenho. Vamos explorar mais
detalhadamente essas técnicas:
</p>
<ul>
<li>
Imagens Responsivas: Imagens responsivas são imagens que se ajustam automaticamente ao tamanho da
tela do dispositivo em que estão sendo exibidas, sem perder qualidade ou causar problemas de layout.
Essa adaptação é alcançada por meio de regras CSS e, muitas vezes, do uso da propriedade max-width:
100%;
</li>
<li>
Otimização de Imagens: A otimização de imagens é o processo de reduzir o tamanho do arquivo de uma
imagem sem comprometer significativamente sua qualidade visual. Isso é crucial para garantir que as
páginas carreguem rapidamente, especialmente em conexões de internet mais lentas ou dispositivos
móveis.
</li>
</ul>
</ol>

<h3 id="titulo4">FRAMEWORKS PARA DESIGN RESPONSIVO</h3>
<ol>
<li>
<h3>Bootstrap.</h3>
</li>
<p>
O Bootstrap é um dos frameworks mais populares para o desenvolvimento de design responsivo e interfaces
web modernas. Desenvolvido pelo Twitter, o Bootstrap fornece uma base sólida de componentes e estilos
pré-construídos, facilitando a criação de layouts flexíveis e adaptáveis a diferentes tamanhos de tela.
</p>
<p>
O Bootstrap é um framework front-end de código aberto que oferece uma coleção de componentes, estilos e
utilitários CSS, juntamente com bibliotecas JavaScript, para acelerar o desenvolvimento web. Ele permite
que os desenvolvedores criem rapidamente layouts responsivos e atraentes sem a necessidade de escrever
código CSS personalizado do zero.
</p>
<br>
<!--<tag><img src="bootstrap.jpg"></tag>-->
<p>Recursos e Características do Bootstrap:</p>
<ul>
<li>
Grid System Responsivo: O sistema de grid do Bootstrap é a base para criar layouts responsivos. Ele
permite a divisão da tela em colunas, facilitando a criação de layouts flexíveis que se adaptam a
diferentes dispositivos.
</li>
<li>
Componentes Pré-Construídos: O Bootstrap oferece uma ampla gama de componentes prontos para uso,
como navegações, botões, formulários, modais, carrosséis, entre outros. Isso economiza tempo e
esforço no desenvolvimento.
</li>
<li>
Tipografia e Estilos de Base: O Bootstrap fornece estilos consistentes para tipografia, cores,
espaçamentos e outros elementos visuais, garantindo uma aparência coesa em toda a aplicação.
</li>
<li>
Responsividade Incorporada: O design responsivo está integrado ao DNA do Bootstrap. Os componentes e
o grid system são desenvolvidos para se ajustar naturalmente a diferentes tamanhos de tela.
</li>
<li>
Media Queries e Breakpoints: O Bootstrap usa breakpoints padrão para adaptar os layouts a diferentes
dispositivos, permitindo um design responsivo eficaz.
</li>
<li>
Flexbox e CSS Grid: Versões mais recentes do Bootstrap incorporaram Flexbox e CSS Grid, melhorando
ainda mais a flexibilidade do layout e a criação de designs responsivos.
</li>
<li>
Customização: Embora venha com estilos predefinidos, o Bootstrap é altamente customizável. Os
desenvolvedores podem escolher quais componentes e estilos usar e ajustá-los conforme necessário.
</li>
<li>
Suporte a JavaScript: Além do CSS, o Bootstrap inclui bibliotecas JavaScript que podem ser usadas
para criar interações e funcionalidades avançadas.
</li>
</ul>
<li>
<h3>Foundation.</h3>
</li>
<p>
Foundation é outro framework front-end popular para o desenvolvimento de design responsivo e criação de
interfaces web modernas. Assim como o Bootstrap, o Foundation oferece uma série de recursos
pré-construídos e estilos que facilitam a criação de layouts adaptáveis a diferentes dispositivos e
tamanhos de tela. O Foundation é um framework front-end de código aberto desenvolvido pela ZURB,
projetado para facilitar o desenvolvimento web responsivo e rápido. Ele oferece um conjunto de
ferramentas e componentes que ajudam os desenvolvedores a criar interfaces consistentes e atraentes em
diversos dispositivos.
</p>
<li>
<h3>Vantagens e Desvantagens dos frameworks.</h3>
</li>
<p>
O conceito de design responsivo se tornou ainda mais relevante na era "mobile-first", que é uma
abordagem estratégica em que o design e desenvolvimento de uma interface começam pelo foco nos
dispositivos móveis, priorizando a experiência do usuário nesses dispositivos e expandindo para telas
maiores. Essa abordagem reflete a crescente importância dos dispositivos móveis na forma como as pessoas
acessam informações, serviços e interagem com a web.
</p>
<p>
A escolha de usar um framework para design responsivo depende das necessidades do
projeto, das habilidades da equipe e das prioridades de desenvolvimento. Embora os frameworks
ofereçam benefícios significativos em termos de velocidade de desenvolvimento, consistência
visual e criação de layouts adaptáveis, eles também têm desvantagens potenciais em termos de
controle criativo, curva de aprendizado e desempenho. Ao escolher um framework, é importante
avaliar cuidadosamente as vantagens e desvantagens em relação aos objetivos e requisitos
específicos do projeto.
</p>
</ol>

<h1>Welcome to Chat Battler Dungeons</h1>
<p>THIS IS STILL IN EARLY ACCESS!</p>
<p>Welcome to what I hope is a new experience in the game-ification of Twitch chat to increase interaction with followers. Currently this bot is only used for https://twitch.tv/thetruekingofspace, but as soon as it's finished it will be available to whoever desires to use it and characters will be accessible cross-channel.</p>
<h1>Getting Started</h1>
<p>First you need to create a battler through the Twitch extension under the video. Once you do this, you can check out and manage your profile here: https://deusprogrammer.com/cbd/battlers/~self</p>
<h1>How Does it Work?</h1>
<p>Well, as soon as you create your battler as layed out above, you will become visible to other players as soon as you perform any of the below actions.</p>
<p>The bot or a mod will spawn monsters during the duration of the chat. They will attack a random person or whoever has the most aggro based on who has done the most damage. Once defeated, they will drop loot for a random participant.</p>
<h1>User Commands</h1>
<p>You can use these commands in chat, or you can use the extension for a push button interface.</p>
<div className="command-grid">
<div className="command-grid-item">
<h2>Ready yourself for battle</h2>
<p>Mark yourself as available for battle with monsters or other players. This state will end after 10 minutes of inactivity.</p>
<div style={{background: "gray", color: "white", paddingLeft: "5px", marginLeft: "10px"}}>
!ready<br/>
<br/>
Example:<br/>
!ready

!attack ~M1
</div>
</div>
<div className="command-grid-item">
<h2>Use an Ability</h2>
<p>Use an ability with a given name on a target. If an ability targets all monsters, you may leave the target off. Also if the ability targets a friendly target, you can leave the target off as a shortcut for yourself.</p>
<div style={{background: "gray", color: "white", paddingLeft: "5px", marginLeft: "10px"}}>

<h1>Game Play Features</h1>
<h2>Your Stats and What they Mean</h2>
<div className="command-grid">
<div className="command-grid-item">
<h3>HP</h3>
<p>Hit points are how much damage your character can take until you are dead. Simple enough.</p>
</div>
<div className="command-grid-item">
<h3>AP</h3>
<p>Action points are used everytime you perform an action like attacking, using abilities, or exploring.</p>
</div>
<div className="command-grid-item">
<h3>STR</h3>
<p>Strength is how hard you hit with your weapon. This stat adds damage each attack you perform.</p>
</div>
<div className="command-grid-item">
<h3>DEX</h3>
<p>How quickly you can attack. If you have a DEX of 0 your cooldown time is 25 seconds. At the maximum value of +5 your cool down times are 5 seconds, and negative DEX has no limit on how much it can slow you down. In the future, DEX beyond +5 will allow for multiple attacks in one cool down period.</p>
</div>
<div className="command-grid-item">
<h3>INT</h3>
<p>This stat is how well you can cast magic. Abilities can use any of these stats to specify if an ability hits or not, but magic type abilities will always rely on intelligence.</p>
</div>
<div className="command-grid-item">
<h3>HIT</h3>
<p>This stat is how well you can aim your attacks. The higher this is, the more likely you are to hit your target with an attack or a non-magic ability.</p>
</div>
<div className="command-grid-item">
<h3>AC</h3>
<p>This stat represents how hard you are to damage. This is generally due to how well you armor protects you.</p>
</div>
</div>
<h2>Special Effects</h2>
<div className="command-grid">
<div className="command-grid-item">
<h3>Damage Area/Target Types</h3>
<p>Some abilities can target more than one enemy, and some can only target monsters or only players in chat.</p>
</div>
<div className="command-grid-item">
<h3>Damage Types</h3>
<p>Weapons and abilities can damage more than just your HP. They can also damage (or heal) your AP or Gold.</p>
</div>
<div className="command-grid-item">
<h3>Buffs/Debuffs</h3>
<p>Some abilities will temporarily increase your stats and make it easier/harder to damage targets, do more/less damage to targets, act faster/slower, or be harder/easier hit.</p>
</div>
<div className="command-grid-item">
<h3>Status Effects</h3>
<p>Some attacks and abilities will harm your HP/AP/Gold over time. An example of this is the poison spell that deals 1d4 every 10 seconds.</p>
</div>
<div className="command-grid-item">
<h3>Triggered Effects</h3>
<p>Some weapons are able to trigger abilities. The Poop Knife for example has a 50% chance of inflicting poison. Triggered abilities are used for free.</p>
</div>
</div>
</div>

# 方法一
在package.json中追加如下配置:
```
"proxy": "http://localhost:5000"
```
说明：
1. 优点：配置简单，前端请求资源时，可以不加任何前缀
2. 缺点：不能配置多个代理
3. 工作方式：当请求了3000不存在的资源时，那么该请求会转发给5000
# 方法二
1.第一步：创建代理配置文件
在src下创建配置文件：
```
src/setupProxy.js
```
2.编写setupProxy配置具体代理规则：
```
const {createProxyMiddleware} = require('http-proxy-middleware');
module.exports = function(app) {
app.use(
createProxyMiddleware('/api1', { // api1是需要转发的请求(所有带有/api1前缀的请求都会转发给5000)
target: "http://localhost:5000", // 配置转发目标地址(能返回数据的服务器地址)即：请求转发给谁
changeOrigin: true, // 控制服务器收到的请求头中Host的值(host：服务器可以通过这个字段知道请求是从哪来的)
/**
* changeOrigin设置为true时，服务器收到的请求头中的host为：localhost:5000
* changeOrigin设置为false时(默认)，服务器收到的请求头中的host为： localhost:3000
*/
pathRewrite: {'^/api1': ''} // 重写请求路径(必须)--去除请求前缀，保证交给后台服务器的是正常请求地址(必须配置)
}),
createProxyMiddleware('/api2', {
target: "http://localhost:5001",
changeOrigin: true,
pathRewrite: {'^/api2': ''}
}),
);
}
```
说明：
1. 优点：可以配置多个代理，可以灵活控制请求是否走代理(即：配置了一定会走代理，即使本地开发服务器有匹配的资源，也不会由本地响应数据，仍然会将请求发给代理的目标服务器)
2. 缺点：配置繁琐，前端请求资源时必须加前缀 |
