摘要
利用函数单向S-粗集和函数单向S-粗集对偶,给出f-规律知识,-f-规律知识,f-规律和-f-规律的概念,利用这些概念,给出规律知识生成的规律之间的关系和积分度量.
Using function one direction singular rough sets and dual of function one direction singular rough sets, the concepts of f-law knowledge, f- law knowledge, f- law and .f-law were given. With these concepts, the relation of laws generated by law knowledge, and the integral metric were both discussed.
