Abstract: Model structures and learning algorithms of Fuzzy Neural Network(FNN) introduced before have been analyzed.In order to overcome their slow convergence and bad overall approximation,a new kind of fuzzy neural network model is presented.The model proposed synthesizes membership functions in the fuzzy level and has simple structure.The inference level includes only two nodes.The simulation result shows the model has fast convergence rate and fine overall approximation and is more effective compared with other models.

摘要: 分析了已有模糊神经网络模型结构与学习算法的特点,针对它们收敛速度慢、全局逼近能力差等不足,提出了一种新型的模糊神经网络模型,其在模糊化层实现了隶属函数的合成,且结构简单、推理层只有两个节点。实验结果表明该模型具有收敛速度快、全局逼近能力强的优点,具有一定的实用价值。
