F-knowledge and Its F-reduction Theorems

By using the dual of one direction singular rough sets,the concepts of F-knowledge and its F-reduction were given;F-reduction theorem of F-knowledge and attribute supplement redundant principle of F-reduction are presented;the dual of one direction singular rough sets is one of the basic forms of singular rough sets;knowledge reduction is a new research direction on rough sets and rough system theory.

分离模糊集合(A^(F),A^(F))与模糊信息智能融合

利用内-分离论域、外-分离论域与分离论域,改进了L.A.Zadeh模糊集合,提出了由内-分离模糊集合与外-分离模糊集合共同组成的分离模糊集合。利用分离模糊集合,给出了模糊信息融合的生成及其属性关系;给出了模糊信息融合中的信息筛以及信息筛分准则,进而提出了模糊信息外-融合-智能检索算法;利用这些理论结果,给出了模糊信息外-融合在疾病分类智能检索中的应用。
