Research on Approximate Set Incremental Updating Method in Covering Generalized Rough Set
摘要
Abstract
This paper researches the variation of approximate set in covering generalized rough set when the attribute set changes, through analyzing the approximate set properties and discussing the relation between boundary and approximate set when the attribute set varies with time, it concludes the variation trend of the approximate set, on the basis of this, the paper proposes an method for updating approximate set incrementally. Examples show the validity of the proposed method.关键词
