WebJul 18, 2024 · Gradient Boosted Decision Trees. Like bagging and boosting, gradient boosting is a methodology applied on top of another machine learning algorithm. Informally, gradient boosting involves two types of models: In gradient boosting, at each step, a new weak model is trained to predict. Updated Sep 28, 2024. WebGradient 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 .
