摘要
本文介绍了MATLAB神经网络工具箱及其常用的工具箱函数;在说明BP网络的模型结构和算法的基础上,讨论了BP网络的训练过程及其设计原则,并用一个典型的两层结构的神经网络实现了具有函数逼近功能的BP网络设计。
Firstly, the MATLAB＇s Neural Networks Toolbox and its common toolbox functions are presented. Then, after the model structure and arithmetic of the BP Neural Network being introduced briefly, its training process and the design principle are analyzed emphatically. At last, with the help of MATLAB Neural Network Toolbox, the design of a typical two - layer - structure BP Neural Network of function approaching is implemented.
