摘要

Mutual information has wide area of application including feature selection and classification. To calculate mutual information, statistical equation of information theory has been used. In this paper, we propose a new criterion for mutual information. It is based on R-value which captures overlapping areas among classes in variables (features). Overlapping area of classes reflects uncertainty of the variables; it corresponds to the meaning of entropy. We compare traditional mutual information and R-value on the context of feature selection. From the experiment we confirm that proposed method shows better performance than traditional mutual information.
