摘要
通过分析决策树ID3算法的基本原理,引出一种改进后的算法(IID3),并以CRM销售业绩相关数据的分类为例介绍数据分类的全过程。由对比可看到改进后算法的优势。
This paper introduces one kind of improved ID3 algorithms of decision tree making in data mining. There is a throughout introduction of how to use this im- proved ID3 algorithms in CRM related sale accomplish- ment data classification,During the contrast you can see the improvement after the calculating way of advantage.
