Task Tracks

• Exploration: Data understanding, distributions, correlation, and insights.
• Library: Baseline model with standard ML libraries.
• Scratch: First-principles implementation using NumPy.
• Optimization: Improvements on top of library or scratch baseline.

Contribution Model

Each issue is open to multiple contributors.

• Multiple PRs can be submitted for the same issue.
• Different approaches, implementations, and optimizations are welcome.

This means even if someone has already submitted a PR for an issue, you are still encouraged to submit your own solution.

Quick Start

1. Fork this folder as its own repo (Linear-Regression).
2. Clone your fork and create a branch.
3. Pick one issue.
4. Work in only one notebook per issue based on track:
   • exploration/exploration.ipynb
   • library/training.ipynb
   • scratch/training.ipynb
5. Run all cells top to bottom.
6. Open a pull request with Closes #<issue-number>.

See CONTRIBUTING.md for detailed rules.
