分类回归树算法的探讨

A Discussion of Classification and Regression Tree

分类回归树是一种优良的决策树算法,有广泛的应用。本文探讨了分类回归树算法及应用,首先回顾了分类回归树的起源及应用,其次分析了分类回归树在均匀成本和非均匀成本下的构造,接着讨论了分类回归树的剪枝和验证过程,最后我们对其进行了总结。

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 nonuniform costs, again discuss the pruning method and validation, finally we summarized.
