摘要
利用粗糙集理论可以高效地进行属性约简和规则提取,并且在规则提取过程中能自动的生成各规则的强度,针对模糊系统设计过程中输入变量的约简、模糊规则难以提取等问题,将粗糙集理论与模糊集理论相结合,提出了一种基于粗集设计模糊系统的方法,并给出了具体的设计过程;最后给出了该设计方法的应用,结果表明了该设计方法的有效性.
Rough set theory can effectively be applied in attribute reduction and rule extraction. To resolve the problems of the reduction of input variables and the difficulty of fuzzy rule extraction etc in the fuzzy system designing process, a method to design fuzzy system is put forward by combining rough sets with fuzzy sets together. Then, a detailed designing process is proposed. At last, an application is proposed to indicate the validity of this method.
