feature-selection's Introduction

feature-selection

很简单的特征选择代码实现。会逐步追加不同的特征选择方法。
读取数据是用的libsvm中的libsvmream。数据下载地址:https://www.csie.ntu.edu.tw/~cjlin/libsvmtools/datasets/
Data文件夹为试验用数据
matlab文件夹为libsvm安装包。里面是已经用mex安装过后的状态
MI文件夹是互信息量计算,源代码为C
method为特征选择方法的文件夹,会陆续更新不同的特征选择方法。
方法:mRMR,reliefF,SVM_REF

这个项目鸽了,没意思
