In applying fuzzy systems , a common problem is that there may exist redundant fuzzy subsets and rules , which can on the one hand increase the complexity of the fuzzy system and wasting the computational capacity , on the other hand make it difficult to describe the fuzzy system with natural language 应用模糊系统时,常常会遇到的一个问题就是系统中可能存在冗余的模糊子集和模糊规则。一方面增加了系统复杂性,浪费了计算能力,另一方面也给使用自然语言来描述系统造成了困难。
In addition we discuss the influence upon training efficiency and performance of this network generated by overlapping state of membership functions of fuzzy subsets . we bring forward modifying parameters of membership functions during samples learning and training . the problem on selecting and optimizing parameters was resolved effectively 本文探讨了模糊子集隶属函数的重叠状态对网络训练效率及性能的影响,提出在网络训练中通过样本学习和训练修正隶属函数的参数,有效地解决了隶属函数参数选取和优化的问题。
In the paper , we use forward neural network model of five layers to map the fuzzy rules . the neural network - fuzzy controller is more improved than previous controller . but there are some deficiencies , such as confirming number of fuzzy subset , picking up fuzzy rules and confirming the initial value of membership 本文采用五层前馈神经网络模型对模糊控制器进行映射,神经网络?模糊控制器的性能虽然较以前的单一控制器有了很大提高,但还存在模糊子集个数的确定、模糊规则的提取和初值的确定等问题。
In this paper , the fuzzy uniform ring , fuzzy uniform subring , fuzzy uniform residue class ring , and direct product of fuzzy uniform rings are defined ; the three necessary and sufficient conditions to describe fuzzy uniform ring by the fuzzy topological ring of type ( qu ) , by fuzzy uniform space and by a family of fuzzy subsets of a ring are obtained 摘要本文定义了模糊一致环概念,研究了它与模糊拓扑环的关系及它与模糊一致空间的关系;给出了借助于环的模糊子集族对模糊一致环的刻画,还引入了模糊一致子环,模糊一致剩余类环与模糊一致环的直积;并讨论了它们的分离性。
fuzzy subset meaning:[Computer] In fuzzy logic , a fuzzy subset F of a set S is defined by a "membership function" which gives the degree of membership of each element of S belonging to F.fuzzy subset перевод:матем. нечёткое подмножество
