Web13 nov. 2024 · Other boosting algorithms don't have these features. Photo by Yerlin Matu on Unsplash. We’ve already discussed 5 boosting algorithms: AdaBoost, Gradient Boosting, XGBoost, LightGBM and CatBoost. Out of them, CatBoost is so special because of its special features that other boosting algorithms don’t have. Generally, … WebGradient Boosting for classification. This algorithm builds an additive model in a forward stage-wise fashion; it allows for the optimization of arbitrary differentiable loss functions. In each stage n_classes_ regression trees are fit on the negative gradient of the loss function, e.g. binary or multiclass log loss.
