| Abstract: | In order to reduce data, discover knowledge from convex serial, and to process convex serial in rough set, convex serial and rough set theory were studied thoroughly and a convex rough set model is presented. Convex rough set and convex rough fuzzy set are defined and the membership function of the convex rough fuzzy set is given. The algorithms of data reduction and rules discovery using convex rough set are also introduced. Finally, an application case is analyzed. The results show that the presented model can be applied conveniently to data reduction and rules discovery with computing better decision. |
