摘要
本文定义了基于覆盖广义粗集的模糊性度量,给出一种度量表示并讨论此种模糊性度量的性质;定义了正负域覆盖广义粗集的模糊度,并通过一个具体实例给出直观解释。
A measure of fuzziness based on covering generalized rough sets is proposed and some characters of this measure are discussed. A measure of fuzziness based on positive-negative region covering generalized rough sets is also put forward. Using a specific example, visual analysis of the new definition is given.
