BP神经网络预测全国私人汽车拥有量

Application of BP Neural Network to Forecast Possession of Private Automobile

利用前向多层神经网络的反向传播算法,即BP算法。采用MATLAB软件建立用于预测的BP神经网络(4-5-2),将已知私人汽车拥有量对BP神经网络进行训练,建立私人汽车拥有量时间序列的预测模型,此BP神经网络可以成功对私人汽车拥有量进行预测计算。

In this paper,the back propagation algorithm of a multilayer feedforw ard neural network was defined as BP algorithm?a BP neural network (4-5-2)was f ound for forecast with MATLAB,the known automobile possession were made to trai n the BP neural network,then,the forecasting model about possession of private automobile that have time sequence would be found . so the BP neural network w ould be able to forecast possession of private automobile.
