摘要
研究了模糊近似空间上的模糊粗糙集,给出了模糊粗糙集的又一定义,讨论了该定义下模糊粗糙集所满足的性质,从理论上说明了该定义的合理性,同时还论证了该定义下模糊粗糙集的近似精度.
In this paper, fuzzy rough sets on fuzzy approximation space are discussed, and another definition of fuzzy rough sets is offered. And its properties are discussed, which explains that the definition is reasonable, meanwhile that the approximate accuracy is given.
