Over three months, Bell contributed a suite of machine learning education resources to the CUAI-CAU/2025_Basic_Track_Assignment repository, focusing on reproducible Jupyter Notebooks for onboarding and experimentation. Bell developed tutorials covering regression, classification, ensemble methods, and dimensionality reduction, applying Python, Pandas, and Scikit-learn to real datasets like Titanic and Boston housing. The work included end-to-end workflows with model evaluation, hyperparameter tuning using HyperOpt, and robust data preprocessing. Bell also improved repository hygiene by standardizing notebook organization and removing outdated files, ensuring maintainability. This approach provided reusable, well-documented assets that supported scalable teaching and streamlined data science experimentation.
