Erika developed a suite of educational data science tutorials and predictive modeling workflows for the CUAI-CAU/2025_Basic_Track_Assignment repository. She created Jupyter notebooks covering foundational topics such as NumPy, Pandas, and Scikit-learn, and implemented clustering with K-Means and regression pipelines to support onboarding and skill development. Erika enhanced predictive analysis by building ensemble models using RandomForest, XGBoost, and LightGBM, incorporating hyperparameter tuning and feature importance visualization. She also prototyped PCA-based dimensionality reduction and maintained code quality through systematic cleanup of obsolete assets. Her work demonstrated depth in machine learning fundamentals and improved the repository’s clarity and maintainability.

May 1, 2025May 2025 highlights for CUAI-CAU/2025_Basic_Track_Assignment. Delivered end-to-end predictive modeling enhancements using ensemble methods (Voting, RandomForest) and gradient boosting (XGBoost, LightGBM) with hyperparameter tuning and feature importance visualization across breast cancer and company-success datasets. Prototyped PCA-based dimensionality reduction with Iris and initial credit-card data experiments. Performed housekeeping to clean obsolete notebooks and PPTX, and added CUAI_BASIC_6 presentation to standardize stakeholder-ready materials. These efforts improved predictive analysis capabilities, reduced maintenance overhead, and strengthened the team's ability to explore, communicate, and derive business insights from model results.
