【摘要】 描述一个多层前馈式模糊神经元网络的学习机制．首先给出网络结构，其连接权值和阀值均为正态模糊数；然后采用模糊数学中区间数运算规则，对传统的ＢＰ算法进行了扩展，提出多层前馈式模糊神经元网络的基于正态模糊数的学习算法，用该算法训练后神经元网络能够完成确定或不确定的信息输入到近似结果输出的非线形映射；最后通过对模糊推理规则的学习考查分析了网络及其学习算法的性能更多还原

【Abstract】 Described a learning algorithm of a multilayer feedforword fuzzy nerual network.First we gve the network architecture whose weights and thresholds are given as bell-shaped fuzzy numbers.Second we adopted the intervals algorithm of the fuzzy sets,extend the traditional BP-algorithm and proposed a bell-shaped fuzzy number based learning algorithm of a multilayer feedforword fuzzy neural network.After training with this proposed algorithm,the fuzzy neural network can perform the non-line ampping between definite or indefinite inputs vectors and crisp outputs.Last by learning the fuzzy reasoning rules we examine and analyze the ability of the proposed fuzzy neural network and its learning algorithm.更多还原
