基于一般二元关系的多粒度粗糙集模型
Multigranulation Rough Set Models Based on General Binary Relations
摘要
Abstract
Multigranulation rough set is a very important expansion of the classical rough set model. It uses a family of equivalence relations instead of a single equivalence relation for approximating target. In the concept of multigranulation rough set model, optimistic and pessimistic cases are different. In this paper, from the viewpoint of general binary relations, the muligranulation rough set model is further expanded. The general binary relations based optimistic and pessimistic rough set models are presented respectively. The properties about these two general rough set models are also discussed.关键词
