WebSep 2, 2024 · 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. There are other distinctions that tip the scales towards LightGBM and give it an edge over XGBoost. WebLightGBM integration guide# LightGBM is a gradient-boosting framework that uses tree-based learning algorithms. With the Neptune–LightGBM integration, the following metadata is logged automatically: Training and validation metrics; Parameters; Feature names, num_features, and num_rows for the train set; Hardware consumption metrics; stdout ...
