摘要
在近似空间(U,θ)的框架下,讨论了直觉模糊特殊集及直觉模糊特殊σ-代数的若干性质,给出了粗糙集的直觉模糊特殊集表示及生成方法.分析了直觉模糊特殊集之间的距离(Hamming距离和Euclidean距离)与决策规则的确定区域之间的关系,并使用Hamming距离或Euclidean距离实现了粗糙集理论中的属性约简.
In the paper, based on approximation space <U,θ>, some properties of intuitionistic fuzzy special sets and intuitionistic fuzzy special σ—algebra are discussed, and intuitionistic fuzzy special set expression and generation of rough set are obtained. The relation between the distance(Hamming distance and Euclidean distance)of intuitionistic fuzzy special sets and areas of certainty of decision rule is analyzed, and reduction of attributes of rough set theory is implemented by using hamming distance and Euclidean distance.
