Abstract：Attribute reduction has been become a research focus in rough set theory.It is a vevy important approach to dimension reduction.This paper proposes a new attribute reduction model, dominance reduction with variable accuracy.The concepts ofβapproximation sets and βdistributed consistent sets are first defined, bast-don dominance relations.Ther, the discernible attribute matrix is constructed by βdistributed consistent sets. Finally, an example is illustated to explain the validity of the proposed method.
