DecisionTreeID3 Machine Learning Algorithm ID3 of Decision Tree( java ) 代码 1. DecisionTree.java 决策树的数据结构 不像python中有一个功能比较强大的字典,所以这里自定义了一个决策树的数据结构(类DecisionTree),两个域: String:用来表示该树(子树)的属性(feature)。 HashMap<String, Object> : key的值...
Decision_tree-python 决策树分类(ID3,C4.5,CART) 三种算法的区别如下: (1) ID3算法以信息增益为准则来进行选择划分属性,选择信息增益最大的; (2) C4.5算法先从候选划分属性中找出信息增益高于平均水平的属性,再从中选择增益率最高的; (3) CART算法使用“基尼指数”来选择划分属性,选择基尼值最小的属性作为划分...
