XGBoost for Classification: Building Accurate and Efficient Models

TalkinSpanishat PyCon US 2023 · 2023-04-19..04-27· [machine-learning]
slides:none on file

Shows using XGBoost for binary classification on the UCI wine dataset: splitting data, fitting and predicting with model.fit, and searching hyperparameters via grid, random and cross‑validation. Demonstrates pipelines that handle missing values and parallel training, reports about 80% test accuracy with higher training scores (overfitting risk), uses feature‑importance plots (chlorides, total sulfur dioxide, alcohol) and applies regularization to reduce variance.
