Abstract

Abstract: 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.

Key words: the dual of one direction singular rough sets, F-knowledge, F-reduction, F-reduction theorem, attribute supplement redundant principle
