一种基于组策略的过滤式特征选择算法
Filter feature selection algorithm based on group mechanism
摘要
Abstract
The MRMR algorithm was fast and effective,and it was popular in the handling of high-dimension data.Motivated by this,this paper proposed a refined MRMR algorithm (MRMRE)based on the group mechanism.To improve the results of feature selection,this algorithm not only considered the relationship between features,but also considered the relationship be-tween feature groups.This algorithm took the MRMR algorithm as the frame,used CCA as the measure and selected SVMs as the base classifier.Massive experiments conducted on generous images and gene sequence data sets in the machine learning da-tabase from UCI show that the proposed algorithm has higher result stability and classification precision in feature selection compared to the MRMR algorithm.关键词
