神经网络结构参数对收敛速度的影响研究

本文介绍了 BP神经网络 ,并通过实验分别研究讨论了初始权值、阈值、学习率以及隐层层数等对网络收敛速度的影响 ,给出了实验数据 ,对如何选取网络结构及参数有着积极的指导意义

Study of the Effect of the Parameters of Neural Network Structure on the Convergence Speed

This paper studies the effect of initial weights,threshold,step size parameter and hid- den layer number of BP neural network on its convergence speed by experiments,also gives the ex- perimental data,and which is of active instructiveness in selection of network structure and pa- rameters.
