第一特征选择的信息论方法

A First Feature Selection Method Based on Mutual Information

提出一种第一特征选择的信息论方法,该方法考虑了第一特征和其他特征组合共同包含的类别信息,即使在非线性分类问题中也表现出良好的第一特征选择性能.

The method for first feature selection based on mutual information is proposed with considering of the joint mutual information between output classes and joint input features.This method works well even in nonlinear classification problems.
