Induction and Reduction of Rejective Decision Rules Based on Rough Sets
摘要
Abstract
Aiming at the drawback that certainty decision rules and the uncertainty decision rules can not give the rejection, this paper proposes a new method to obtain rejective decision rules.By analyzing the measure factors of the decision rules, two kinds of reductions algorithms are defined,which can maintain the lower and upper approximation.A method of discernibility matrix is presented to obtain the reductions, from which the rejective decision rules can be simplified.Some numerical examples show the effectiveness and utility of the algorithm.关键词
