about an item (represented in the branches) to conclusions about the item’s target value (represented in the leaves). It supports both continuous and categorical features. Extra Trees Regression An averaging algorithm based on randomized decision trees. Gradient Boosting Regression Produces a regression prediction model in the form of an ensemble of decision trees. It supports both continuous and categorical features. LGBM Regression Gradient boosting framework that uses tree-based learning algorithms. Linear Regression Models the linear relationship between a scalar-dependent variable y and one or more explanatory variables (or independent variables) x. Random Forest Regression Constructs multiple decision trees to produce the mean prediction of each decision tree. It supports both continuous and categorical features. Ridge Ridge regression is similar to Ordinary Least Squares but imposes a penalty on the size of coefficients. XGBoost Regression GBRT is an accurate and effective off-the-shelf procedure that can be used for regression problems. Gradient Tree Boosting models are used in a variety of areas including Web search ranking and ecology.
about an item (represented in branches) to conclusions about the item’s target value (represented in leaves). Supports both binary and multiclass labels, as well as both continuous and categorical features. Extra Trees Classifier An averaging algorithm based on randomized decision trees. Gradient Boosted Tree Classifier Produces a classification prediction model in the form of an ensemble of decision trees. It only supports binary labels, as well as both continuous and categorical features. LGBM Classifier Gradient boosting framework that uses leaf-wise (horizontal) tree-based learning algorithm. Logistic Regression Analyzes a data set in which there are one or more independent variables that determine one of two outcomes. Only binary logistic regression is supported Random Forest Classifier Constructs multiple decision trees to produce the label that is a mode of each decision tree. It supports both binary and multiclass labels, as well as both continuous and categorical features. XGBoost Classifier Accurate sure procedure that can be used for classification problems. XGBoost models are used in a variety of areas including Web search ranking and ecology.
