决策树id3算法-阿里云

决策树ID3算法和C4.5算法实战 老师给的题目：代码实现【两种算法合在一个文件里】： 1. from numpy import * 2. 3. def createDataSet(): 4. dataSet = [[1, 1, 1, 0, 'no'], 5. [1, 1, 1, 1, 'no'], 6. ...

【机器学习-决策树模块-基础算法-1)ID3算法】决策树最最最基础的三个算法：对于什么是决策树，决策树的基本概念网上已经多的不能再多了这里不再赘述，直接切入正题，决策树的算法以及实现。至于遇到的必须要掌握的信息论相关知识，我会在这篇文章里根据自己遇到的知识来持续更新：点击打开链接：（http://blog.csdn.net/qq_3...
