Getting Started

Before diving into the pipeline, I encourage you to explore your data and try different models using the data_exploration.ipynb notebook. It's essential to identify which model performs best for your specific use case.

Utilities and Logging

To ensure high-quality code and maintainability, I've included a utilities module in src/utils/.

• config.py: A configuration parser utility that helps in dynamically reading your settings from config/settings.ini. It ensures that your scripts have access to up-to-date configurations without hardcoding values.
• logger.py: A custom logging utility that wraps around Python's built-in logging module. It provides a consistent logging interface for your application, making debugging and monitoring the pipeline's performance easier. You can track the execution flow, errors, and informative messages that help in maintaining a clean execution log for audit and debugging purposes. To utilize the logger, simply import it in your scripts and use it to log messages at different severity levels

Customize Your Configuration

Set data sources and model parameters in config/settings.ini.

• Adapt src/pipeline/stage_01_ingestion.py for your data ingestion needs.

Executing the Pipeline

Run the pipeline with these commands:

python main.py ingest
python main.py preprocess
python main.py train
python main.py evaluate

Tailoring the Pipeline Steps

Customize the scripts in src/pipeline/ to match your machine learning tasks.

I used Logistic Regression for Fake News Detection; feel free to adapt or choose a more complex model.

For API and Docker Deployment

• Tailor the api/api.py to set up your prediction endpoints.
• Adjust the Dockerfile to bundle your API and model into a container for deployment.

If you're unfamiliar with Docker or how to use it, start by reading this article: How Docker Containers Work, and then watch the video: Build YOUR OWN Dockerfile.

CI/CD Integration

Take advantage of the .github/workflows templates included in this project to set up Continuous Integration (CI) and Continuous Deployment (CD) with GitHub Actions and Azure. CI/CD helps automate steps in your software delivery process, such as initiating automatic builds and deployments.

For a deeper understanding of CI/CD principles and benefits, read the article: Building an Effective CI/CD Pipeline: A Comprehensive Guide.

Deployment on Azure using GitHub Actions

To get started with deploying on Azure, ensure you have an Azure subscription. If you're a student, you're in luck! You can sign up for the Azure for Students offer, which provides you with $100 in Azure credits for the first year.

Here's a quick rundown:

1. Sign up for Azure if you haven't already. If you're a student, access your free credits through the Azure for Students offer.

2. Once you have your subscription, log into the Azure Portal and create a resource group.(Ask ChatGPT that how to create a resource group using azure portal or azure CLI)

3. With your environment set up, you'll use the Azure CLI for the next steps. If you don't have it installed, follow the instructions here: Install the Azure CLI.

4. After setting up the CLI, use the az login command to log in to your Azure account.

5. Proceed with the rest of the required steps to configure your GitHub Actions for Azure deployment. A detailed tutorial is available here: Deploying Docker to Azure App Service.

This setup allows you to deploy any containerized application seamlessly using GitHub Actions directly to Azure App Service.

Integrating the Fake News Detection API

I have developed a Fake News Detection API that is ready to be integrated into your applications. You can easily leverage this API for real-time predictions by sending requests to the /predict endpoint. The model backing this API boasts a high F1 score of 0.98 on testing data, indicating its reliability and precision.

Show Your Support

If this project has been beneficial to you, please consider giving it a star⭐ on GitHub! Your support encourages further development and helps others discover the project.

Thank you for exploring this MLOps pipeline template. It has been a valuable learning experience, and I hope it will be equally insightful for you. :)

!Note

It can be significantly improved by you. While version control could elevate your project, I've avoided using it here to keep things simple. Additionally, more advanced technologies could be considered
