摘要
主要讨论模糊等价关系在任意阈值的情况下对应的商空间,以及如何在不同阈值对应的商空间之间分层递阶构建归一化等腰距离函数,得到分层递阶的商空间结构,并讨论模糊等价关系的运算(交、并)与商空间的合成之间的关系.
In this paper, the fuzzy quotient space theory for the cut-relation of fuzzy equivalence relation with any threshold is discussed. A method is proposed for hierarchically constructing normalized isosceles distance function between different quotient spaces. And a hierarchical structure of fuzzy quotient space is constructed. The relation between the operations (intersection and combination )of fuzzy equivalence relation and the synthesis of quotient spaces is discussed.
