Attribute classification based on the rough sets theory
基于粗糙集理论的属性分类

According to Rough sets theory,it is analyzed that the variation of the condition attribute partition contributes to the support degree of decision subsets and decision rules in the decision system.The method of selecting the best attribute classification is induced.Criteria and algorithms for the best attribute classification are introduced.Finally,the validity of algorithm 2 is verified through a simulation result.
