Web1 day ago · XGBoost has long been used as an efficient algorithm for classification problems. Its simplicity, high stability, scalability, and ability to prevent overfitting make XGBoost a robust classifier, particularly in high-dimensional datasets. Hypertuning further boosted the performance of XGBoost, demonstrating the potential of this classifier ... WebJan 18, 2024 · XGBoost, LightGBM, and CatBoost all share a common limitation: they need smooth (mathematically speaking) objectives to compute the optimal weights for the leaves of the decision trees. This is not true anymore for XGBoost, which has recently introduced, support for the MAE using line search, starting with release 1.7.0
