CART(Classification and Regression Trees)是一种常用的决策树算法,既可以用于分类问题,也可以用于回归问题。CART算法由Breiman等人于1984年提出,是一种基于递归二分划分的贪婪算法。以下是对CART算法的详细解释: 1. 决策树的构建过程: CART算法通过递归地将数据集划分为越来越纯的子集,构建一棵二叉树。具体过程如下:...
决策树算法之分类回归树 CART(Classification and Regression Trees)【1】,程序员大本营,技术文章内容聚合第一站。
Classification and Regression Trees(简称CART),指的是可用于分类或回归预测建模问题的决策树算法。在本节中,我们将重点介绍如何使用CART解决分类问题,并以Banknote数据集为例进行演示。 CART模型的表示形式是一棵二叉树。每个节点表示单个输入变量(X)和该变量的分割点(假定变量是数字化的)。树的叶节点(也称作...

Unlike many other statistical procedures, which moved from pencil and paper to calculators, this text's use of trees was unthinkable before computers. Both the practical and theoretical sides have been developed in the authors' study of tree methods. Classification and Regression Trees refle... (...

C4.5算法可以修剪(prune)决策树,修剪是通过更少的叶节点来替换分支,以缩小决策树的规模。scikit-learn的决策树实现算法是CART(Classification and Regression Trees,分类与回归树)算法,CART也是一种支持修剪的学习算法。 2.3 基尼不纯度 前面我们用最大信息增益建立决策树。还有一个启发式方法是基尼不纯度(Gini ...
