WebSep 2, 2024 · But, it has been 4 years since XGBoost lost its top spot in terms of performance. In 2024, Microsoft open-sourced LightGBM (Light Gradient Boosting Machine) that gives equally high accuracy with 2–10 times less training speed. This is a game-changing advantage considering the ubiquity of massive, million-row datasets.
