the dual of one direction singular rough sets%(F)-knowledge%F-reduction%F-reduction theorem%attribute supplement redundant principle
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.
