Abstract

This paper presented a novel approach, based on an integrated use of fuzzy and rough set theories, to greatly reduce data redundancy. The information framework in rough set theory is introduced in fuzzy-rough set. Mutual information-based algorithm for attribute reduction in fuzzy rough set is introduced and illustrated with a simple example. Experimental result shows that it is an effective technique.
