Related Issue

The Machine Learning folder was missing a subsequent README file, which could be confusing for beginners. In an effort to assist and improve clarity, I have added a README file within the Machine Learning folder. This README provides information about the project, including its goals, project types, and folder structure.

Describe the changes you've made

I have made updates to the README.md file to provide a more detailed description of the machine learning projects in this repository. The changes include expanding on the goals of the project, explaining the project types covered, and giving an overview of the folder structure.

These updates aim to provide clearer information and attract more beginners to explore the projects. I believe these additions will enhance the understanding of the repository's content and help users navigate through the different machine learning project options available.

Please review the changes and consider merging them into the main branch. I appreciate your time and consideration.
