摘　　要：在对数据挖掘决策树的基本概念和常用算法进行介绍的基础上,针对生成决策树的常见问题提出了相应的处理方法。Decision tree is a kind of data mining technologies which are used most widely and have the biggest influence at present.At the same time,there are many algorithms that produce decision trees,but some problems should be solved in all of these algorithms.Such as the decision tree overfit the samples and the choice of testing attribution and the relation between attributions.
