Web11.1.1 Decision trees. A decision tree (also known as a classification and regression tree 16 or “CART”) is a tree-like flowchart that assigns class labels to individual observations. Each branch of the tree separates the records in the data set into increasingly “pure” (i.e., homogeneous) subsets, in the sense that they are more likely ...
