Developed a comprehensive Jupyter Notebook for the gato365/stat_331_winter2025_notes repository, focusing on machine learning model validation and hyperparameter tuning. The notebook provided end-to-end guidance on techniques such as holdout sets, cross-validation, bias-variance trade-off, learning curves, and grid search, all implemented using Python and Scikit-learn. Practical code examples and visualizations were included to illustrate each method, supporting reproducible evaluation workflows and clearer documentation for team onboarding. The work emphasized best practices in model selection and validation, enabling accelerated development cycles and improved confidence in ML outcomes, while establishing a reusable reference for future data science projects.
