Gradient lifting decision tree

WebDecision Trees (DTs) are a non-parametric supervised learning method used for classification and regression. The goal is to create a model that predicts the value of a target variable by learning simple decision rules inferred from the data features. A tree can be seen as a piecewise constant approximation. WebMay 14, 2024 · XGBoost uses a type of decision tree called CART: Classification and Decision Tree. Classification Trees: the target variable is categorical and the tree is used to identify the “class” within which a target variable would likely fall. Regression Trees: the target variable is continuous and the tree is used to predict its value.
