Abstract:
Based on deep research of rough set theory, an improved ROUSTIDA algorithm is proposed according to the decision rules independence principle in this paper. It efficiently solves the potential contradiction between decision rules comparing with the ROUSTIDA algorithm. Practice proves the efficiency of the algorithm.
