CART算法(转载) 分类与回归树(classification and regression tree, CART)模型是应用广泛的决策树学习方法,同样由特征选择、树的生成和剪枝组成,既可以用于分类也可以用于回归...作为剪枝的标准。 CART生成决策树的生成就是递归地构建二叉决策树的过程,对回归树用平方误差最小化准则,对分类树用基尼系数最小化准则,...
Cart 树是一种比较经典的决策树算法,现在许多模型也是基于其发展而来,比如GBDT,LightGBM等。最近用python复现了一下cart二分类大体思路,在这里简单记录其中的学习过程。 Cart树如何训练得… Burlington CART生成与剪枝算法详解 月来客栈发表于跟我一起机... 分类与回归树(CART):核心 Stabl...发表于机器学习与...打...
