Granular computing model in rough set

Chaohai Tao

Open publisher page 2 citations

Abstract

Granular computing is a new intelligent computing theory based on partition of problem concepts.Inconsistent decision table is an important aspect in rough set theory,and the equivalent relation in rough set theory is used to express equivalent granule.A de-composing model of granular computing in decision information system is developed.Furthermore,one also presents the method of getting core attributes based on granular mode in decision table.
