摘要: 基于吴鹏等提出的k度限制相容关系模型,讨论在集值不完备信息系统上的约简,给出集值不完备信息系统属性约简的判定定理和辨识矩阵,得到集值不完备信息系统知识约简的具体操作方法。
关键词: Rough集, 集值信息系统, 限制相容关系, 知识约简
Abstract: Based on k-degree tolerance relation and dominance relation propoled by Wu Peng,et al,this paper discusses the knowledge reduction of the set-valued incomplete information system,and presents the decision theorem,the discernibility matrix,and the specific operation method for the knowledge reduction of the set-valued incomplete information system.
Key words: Rough set, set-valued information system, limited tolerance relation, knowledge reduction
