基于一般二元关系的知识粗糙熵与粗集粗糙熵

Entropy of Knowledge and Rough Set Based on General Binary Relation

针对一般二元关系(自反的),通过引入知识粗糙熵来刻画知识的粗糙性和粗集粗糙性,为以一般二元关系为基础的信息系统中知识的获取提供了理论依据.

In this paper, the roughness of knowledge and rough set is denoted by their rough entropy with respect to general binary relation, which provides theory basis for knowledge acquisition in information systems based on general binary relation.
