Using MLaC, expert data scientists can have better control over experimentation, optimization & deployment of ML Models.\n\nMLaC has four unique components. \n\nGenerate Code: Generates the code for each pipeline component of the selected use case i.e., data transformations, feature engineering, model training and prediction. This code can further be used to retrain the model on the latest data and can also be used to create a container for each component. The user will find the code in the local system through path: C:\\Users\\yashaswini.ragi\\AppData\\Local\\HCLT\\AION\\target\\AION_375_1\\publish\\MLaC\n\nGenerate Container (Local):\n\nPre-requisite:\n\n Local Machine should have docker installed.\n\nCreate docker images for each of the components by running the docker file present in each component.\n\n Once the docker images are ready to consume, create the container from the images and run that container sequentially as mentioned below:\n\nModel Monitoring > Data Ingestion > Data Transformation > Feature Engineering > Model Training > Model Registry > Model Serving\n\nUser can see the status of each step through the shell as shown below.\n\nExec Pipeline (Local):\u00a0Another way to run this component without using docker is to run the command run_pipeline.py in aion shell.\n\nThe command will execute each component one by one locally in the user system. \n\n\n\nExec Kubeflow pipeline: Using Kubeflow user can run all the components as a single pipeline, which is managed by Kubeflow internally.\n\nGitHub Upload:\u00a0Upload the Generated Code to the GitHub repository.\n\nMLaC service can be used for prediction through PostMan following the steps given below-\n\nOpen PostMan desktop app.\n\nConfigure a POST request with the predict API of the form http://<localhost:port>//AION//<usecasename>/predict  \n\nEg: http://127.0.0.1:8094//AION/AI0192/predict.\n\nSelect authorization as Basic Authorization",

Federated learning (or collaborative learning) is an approach used to train a decentralized machine learning model across multiple partitions. The federated learning participants can be edge devices, data centers, smartphones, medical wearables, IoT devices, vehicles, etc. They collaboratively train a shared model while keeping the training data locally without exchanging it. Each participant downloads the model from the server. They train it on their private data, then summarize and encrypt the model\u2019s new configuration. The model updates are sent back to the cloud, decrypted, averaged, and integrated into the centralized model. Then, this centralized model is once again shared with participants for the next round of federated learning. Iteration after iteration, the collaborative training continues until the model is fully trained. In AION, Federated Learning is supported for the following algorithms: Logistic Regression, Linear Regression, and Simple Neural Network (SNN). \n\nPython Package: Python Package creates a WHL File of a trained model so that the user can further use that file in testing and prediction. If the user wants to consume the trained model for prediction in some system where AION is not there, then either the user can install a python package or use the docker images.\n\nPython package can be consumed by following the steps:\n\nClick on the python package icon from the packages tab and as a result whl file will get download.\n\nOpen the command prompt and type the command: python -m pip install whl_file_path and press Enter.",

        "output": "Model container: The model container creates a docker image of the trained model so that user can use that image anywhere, pull the image, and perform testing. If the user wants to consume the trained model for prediction purpose in some system where AION is not there, then either the user can install it as python package or use the docker images. \n\nThere are two cased to create a docker container:\n\nWhen the Docker is installed in the machine user can click on the docker and it gets created. \n\nIn case Docker is not installed, running aion will throw an error. For that user can copy the mentioned path file and put in other machine where the docker should be installed and can build the image there also using docker build command.\n\nThe model container also supports CORS (Cross-Origin Resource Sharing) protocol to mitigate the default security policy, Same-Origin Policy (SOP) used by the browsers to protect resources. The same-origin policy is a critical security mechanism that restricts a documents or script loaded by one origin can interact with a resource from another origin.\n\n\n\nCommand to enable CORS: python aion_service.py ip 0.0.0.0 -p 80 -cors \u201chttp://localhost:5000\u201d\n\nHomomorphic Encryption:  Homomorphic Encryption (HE) combines data encryption with privacy protection. A homomorphic cryptosystem is like other forms of public encryption in that it uses a public key to encrypt data and allows only the individual with the matching private key to access its unencrypted data. However, what sets it apart from other forms of encryption is that it uses an algebraic system to allow a variety of computations on the encrypted data. AION Supports only the XGBoost algorithm.\n\nTo publish the trained model, go to the Packages tab and click on the icons of above-mentioned packages accordingly. \n\nUsers can select any model or any version of that model for publishing so that it can be installed on the system for faster inference.",
