一种新的双论域上模糊粗糙集
A new fuzzy rough set model on two different universes
摘要
Abstract
The extension of rough set is a hot research direction in rough set theory.The aim of this paper is to present a new extension of rough set model over two different universes which is a new fuzzy rough set on two universes based on a fuzzy compatible relation.The low and upper approximation of a fuzzy set are defined.Moreover,several properties of this rough set model are also investigated.关键词
