【摘要】 人工神经网络是一种非线性的动态数学模型,具有很强的函数逼近功能。本文先介绍BP网络结构,然后介绍MATLAB神经网络工具箱中关于神经网络系统设计的函数,并在此基础上设计一个BP网络来验证神经网络的函数逼近能力。更多还原

【Abstract】 Artificaial Neural Network are a nonlinear dynamic mathematic model and have a strong ability to approximate function. Here, the structure of BP Feed-Forward Neural Networks and MATLAB toolbox based functions design of Neural Network system are introduced, based on which, a BP Network is designed to verify the ability of function approximation.更多还原
