说明：  id3算法进行决策树生成 以信息增益最大的属性作为分类属性，生成决策树，从而得出决策规则。id3的源码决策树最全面最经典的版本.id3决策树的实现及其测试数据.id3 一个有用的数据挖掘算法，想必对大家会有所帮助！
(id3 decision tree algorithms to generate information gain the greatest attribute as a classification attributes, generate decision trees to arrive at the decision-making rules. id3 the most comprehensive source Decision Tree classic version. id3 decision tree and its test data. id3 a useful data mining algorithms, surely they will be helpful!)
