Abstract :
Based on an extension model of rough set theory, a novel method of generating optimal decision rules directly from incomplete information systems is proposed in this paper. Through this method, the minimum condition attributes set of all objects can be obtained without data reduction for every single object, and the generalized decision rules can be generated from the original incomplete systems. Two examples show that the method is well suited for both consistent information systems and inconsistent information systems.
