Create a Comprehensive ML Tutorial Series

Description:
Many folders contain valuable code but lack beginner-friendly explanations. Add tutorial-style documentation in each folder to help users understand the theory and implementation of the algorithms.

Expected Tasks:

• Add a README.md to subfolders like computer-vision, data-analysis, etc., containing:
  • A brief introduction to the domain.
  • A step-by-step walkthrough of a key implementation (e.g., how KNN works).
  • Sample input and expected output.
  • Hyperlink to helpful resources (e.g., scikit-learn, Coursera, blog posts).
• Ensure the code runs correctly with the tutorial.
• Add a table of contents or index in the root README.md to guide users to these tutorials.

Stretch Goal:

• Add visual diagrams or flowcharts using Markdown-supported images or ASCII diagrams.
