摘要：

以属性测度空间的粗糙集模型为基础,针对S-粗集中元素的动态特性,提出了双向S-属性粗糙集的概念,讨论了双向S-属性粗糙集的性质,并结合实例就双向S-属性粗糙集的精度进行了讨论。

Abstract:

Considering the dynamic characteristics of the elements in rough sets, a two direction singular attribute rough sets model is presented based on the theory of attribute sets and attribute measure. The properties of the two direction singular attribute rough sets, the precision of it are discussed by an example.

Key words: two direction singular rough sets; attribute sets; attribute measure; rough sets; roughness measure
