摘要
以区间属性值信息系统为研究对象,建立了其中的自反模糊关系、模糊信息粒以及模糊粗糙集。定义了两种新的粗糙熵对区间属性值信息系统中的不确定性因素进行度量,并进行了其单调性的讨论。
Taking the information systems with attributes of interval values as the study object, the reflexive fuzzy relation, fuzzy information granules and fuzzy rough set were formed respectively. Moreover, in order to measure uncertainty factors in the information systems with attributes of interval values, two newly defined rough entropies were given and their monotonicity was discussed.
