PROFILE
Tianshu Feng
During two months on the jdpipping/summer-lab repository, Tianshu Feng developed a suite of sports analytics and machine learning tools spanning basketball, baseball, NFL, MLB, diving, and Spotify data. He engineered modular R and Stan pipelines for Bayesian modeling, regression analysis, and permutation testing, enabling reproducible workflows and visualization-ready outputs. His work included a basketball analytics suite, park effects analysis for baseball, NFL win probability modeling, and a Spotify song feature prediction pipeline using XGBoost with cross-validation. By addressing model reliability through targeted bug fixes and robust data preprocessing, Tianshu demonstrated depth in statistical modeling, data engineering, and machine learning.
