| Abstract: | By employing one direction S-rough sets, the concepts of knowledge addition and knowledge battlement generated by knowledge addition were presented, where knowledge battlement has dynamic characteristic. Then rough knowledge battlement generation was given, and the generation principle and the reversion theorem of rough knowledge battlement were proposed. Furthermore, the discernibility metric of rough knowledge battlement was given, and the recognition rule and recognition theorem of rough knowledge battlement were proposed. Finally the applications were given. |
