查询词典 entropy

This paper applies the entropy concept of information theory to feature selection,and defines two information measurements overlap entropy and error entropy that are used to evaluate features.Then the physical meanings of the two definiens are explained.The crucial problem about how to divide the interzones is provided in the following.
