What is CART?
CART: Classification and Regression Trees: a tree-building algorithm that always makes binary splits, uses Gini impurity for classes and squared error for numbers, and then prunes back. It is the basis of scikit-learn's tree models and most forest and boosting libraries.
CART: an example
DecisionTreeClassifier in scikit-learn implements an optimised version of CART.
