摘要
提出一种基于粗糙集的区间值属性决策表的有序规则获取方法。首先根据区间数之间基于可能度的序关系,将区间值属性决策表转化为二元决策表,然后利用粗糙集理论进行分析并推理出最优规则,最后再将二元决策表的规则转化为区间值属性决策表的有序规则。实验分析表明了该方法的有效性。
A new approach rough set-based for ordering rules acquisition in interval valued decision table is presented.This paper firstly transforms interval valued decision table into the binary decision table according to an order relation between interval numbers possibility-based,then induces optimal rules using rough set theory.Finally,rules induced in binary decision table are transformed into ordering rules in interval valued decision table.Simulation results show that the method is effective.
