Gradient boosting is a machine learning technique used in regression and classification tasks, among others. It gives a prediction model in the form of an ensemble of weak prediction models, which are typically decision trees. When a decision tree is the weak learner, the resulting algorithm is called gradient-boosted trees; it usually outperforms random forest. A gradient-boosted trees … WebbThis implementation is for Stochastic Gradient Boosting, not for TreeBoost. Both algorithms learn tree ensembles by minimizing loss functions. TreeBoost (Friedman, …
