决策树(Decision Tree)CART算法 1. CART算法的认识 Classification And Regression Tree,即分类回归树算法,简称CART算法,它是决策树的一种实现,通常决策树主要有三种实现,分别是ID3算法,CART算法和C4.5算法。 CART算法是一种二分递归分割技术,把当前样本划分为两个子样本,使得生成的每个非叶子结点都有两个分支,因此...
● 基尼指数（Gini Impurity）：另一种衡量数据集纯度的指标，越小表示纯度越高。在CART（Classification and Regression Tree）算法中，基尼指数常用于替代信息增益作为节点划分的依据。2. 其他度量与算法 ● 卡方检验（Chi-Squared Test）：用于评估特征与类别之间的关联性，适用于离散型特征。在某些决策树实现中，...
