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.
Web31 jul. 2024 · LS_Boost are based on randomized neural networks’ components and variants of Least Squares regression models. I’ve already presented some promising examples of use of LSBoost based on Ridge Regression weak learners. In mlsauce ’s version 0.7.1 , the Lasso can also be used as an alternative ingredient to the weak learners.
