| 摘 要： | 针对S-粗集中元素的动态特性,给出了内、外边界和外边界熵的概念,将传统的粗糙度与外边界熵结合进来,提出了一种新的S-粗集不确定性的度量方法,讨论了这一度量的特性,并通过实例说明这一新的度量方法的合理性与简便性。

| Abstract: | Considering the dynamic characteristics of the elements in singular rough sets,the concepts of inside/outside boundary and outside boundary entropy are defined.After discussing the properties of this measure,a new uncertainty measure of singular rough sets by combining traditional roughness with outside boundary entropy is provided.In the end,an example shows the rationality and simplicity of the new uncertainty measure. |
