Gradient lifting decision tree
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. WebAt the same time, gradient lifting decision tree (GBDT) is used to reduce the dimension of input characteris- tic matrix. GBDT model can evaluate the weight of input features under different loads ...
