網頁2024年8月20日 · CART is a DT algorithm that produces binary Classification or Regression Trees, depending on whether the dependent (or target) variable is categorical or numeric, respectively. It handles data in its raw form (no preprocessing needed) and can use the same variables more than once in different parts of the same DT, which may uncover … 網頁CART分类树算法 ID3中使用了信息增益选择特征,增益大优先选择。C4.5中,采用信息增益率选择特征,减少因特征值多导致信息增益大的问题。CART分类树算法使用基尼系数选择特征,基尼系数代表了模型的不纯度,基尼系数越小,不纯度越低,特征越好。
