Forecasting outcomes in collegiate basketball tournaments is inherently difficult due to the volatility and non-linear dynamics of team performance. This paper introduces a predictive framework designed for the March Machine Learning Mania 2026 competition, addressing both Men's and Women's NCAA tournaments. By applying advanced statistical feature engineering, the study moves beyond simple win-loss records to derive refined metrics such as possession- based offensive and defensive efficiency, effective field goal percentage (eFG), and pace. At the core of the framework is a weighted ensemble model that integrates three complementary machine learning algorithms: Logistic Regression, XGBoost, and Random Forest. Optimized weights—20% for Logistic Regression, 50% for XGBoost, and 30% for Random Forest—enable the ensemble to combine the interpretability of regression w.. Read More»
