By using two-directional S-rough sets, the concepts of (f, ¯ f)-interference generation and (f, ¯ f)- interference law generation of knowledge, F-interference generation and F-interference law generation of two-directional S-rough sets are proposed. Based on the concepts above, the relation theorems between F- interference loss and F-interference degree, the relation theorems between F-interference loss law and F-interference degree law, the discernibility theorems between F-interference and F-interference law are presented. At last, the recognition criterion of F-interference law and its application are given.
