Previously, I read Random Forest and decision Tree extensively. Now I have implemented a specific decision Tree algorithm: CART (Classification and Regression Tree ). CART is a decision tree algorithm proposed by Breiman, Friedman, Olshen, and Stone in 1984. Although it is not the first decision tree in the machine learning field, however, it is the first decision tree with complex statistical and probabili

Absrtact: The aim of this experiment is to learn and master the classification regression tree algorithm. The cart provides a common tree growth framework that can be instantiated into a variety of different decision trees. The cart algorithm uses a binary recursive segmentation technique to divide the current sample set into two sub-sample sets, so that each non-leaf node of the resulting decision tree has
