Developed a comprehensive suite of educational machine learning notebooks for the CUAI-CAU/2025_Basic_Track_Assignment repository, focusing on end-to-end workflows for data analysis, model training, and evaluation. Leveraged Python, Jupyter Notebook, and scikit-learn to demonstrate core concepts such as classification, regression, dimensionality reduction with PCA, and ensemble methods including Random Forest and XGBoost. Integrated reproducible pipelines for hyperparameter tuning using Hyperopt and GridSearchCV, with clear guidance on metrics like accuracy, precision, and recall. Delivered ready-to-run materials supporting hands-on learning, reproducible experimentation, and curriculum deployment, while maintaining repository hygiene and documentation to facilitate onboarding and scalable educational use.

May 1, 2025May 2025 monthly summary for CUAI-CAU/2025_Basic_Track_Assignment: Delivered a comprehensive ML Educational Notebooks suite enabling hands-on learning of core ML concepts. The notebooks cover classification metrics (accuracy, precision, recall), PCA visualization (Iris), regression basics, hyperparameter tuning, feature importance, and ensemble methods (Voting Classifier, Random Forest, Gradient Boosting, XGBoost) with Hyperopt for tuning. Established an initial setup for credit card default analysis to support risk analytics exploration. This work provides an end-to-end ML workflow—from data preparation to model evaluation—within a reproducible, Git-tracked framework. Key outcomes include ready-to-run notebooks for teaching and experimentation, clear guidance on evaluation and model selection, reproducible experiments across model families, and a solid foundation for future risk modeling projects.
