| Abstract: | Classification and regression tree,a wide range of applications,is a good decision tree algorithm.This article discussion it.In first we review the origin and application of the classification and regression tree,in the second we analyze the construction of the classification and regression tree in the cost of uniform and non-uniform costs,again discuss the pruning method and validation,finally we summarized. |
