Feature selection based on mutual information criteria of max-dependency, max-relevance, and min-redundancy
Article
Article
Hanchuan Peng; Fuhui Long; Chen Ding · IEEE Transactions on Pattern Analysis and Machine Intelligence · 2005
Feature selection is an important problem for pattern classification systems. We study how to select good features according to the maximal statistical dependency criterion based on mutual information. Because of the dif...
