在前文介绍过 blending ,这实际上就是 meta algorithm,只是将已获得的假设函数做一个融合。 而bagging 属于 learing 的一种,也就是说在融合过程中获取假设函数。bagging 与 AdaBoost 区别于一个是 uniform 而另一个不是。而 stacking 实际上就是将已有的假设函数集的输出作为特征输入到一个机器学习模型中,在训练...

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...
