recursive feature elimination ( RFE ) 通过学习器返回的 coef_ 属性 或者 feature_importances_ 属性来获得每个特征的重要程度。 然后，从当前的特征集合中移除最不重要的特征。 在特征集合上不断的重复递归这个步骤，直到最终达到所需要的特征数量为止。 RFECV 通过交叉验证来找到最优的特征数量。 如果减少特征会造成性能损失，那么将不会去除任何特征。 这个方法用以选取单模型特征相当不错，但是有两个缺陷，一，计算量大。 二，随着学习器（评估器）的改变， …

2021年5月11日 · 递归特征消除（RFE）是一种特征选择方法，用于通过递归减少特征集的大小来找出模型性能最佳的特征。RFE的工作原理是反复构建模型并选择最重要的特征（基于模型权重），然后去除最不重要的特征，直到达到指定的特征数量。这个过程依赖于模型对特征重要 ...
