DC学院学习笔记（二十一）：用特征选择方法优化模型（二）

随机森林特征选择法 —— Gini Importance 原理：使用Gini指数表示节点的纯度，Gini指数越大纯度越低。然后计算每个节点的Gini 指数 - 子节点的Gini 指数之和，记为Gini decrease。最后将所有树上相同特征节点的Gini decrease加权的和记为Gini importance，该数值会在0-1之间，该数值越大即代表该节点（特征）重要性越大。涉及参数计算....

DC学院学习笔记（二十）：用特征选择方法优化模型

特征选择的定义：特征选择( Feature Selection )也称特征子集选择( Feature Subset Selection , FSS )，或属性选择( Attribute Selection )。是指从已有的M个特征(Feature)中选择N个特征使得系统的特定指标最优化，是从原始特征中选择出一些最有效特征以降低数据集维度的过程，是提高学习算法性能的一个重要手段，也是模式识别中关....
