摘要
利用生物发酵过程运行数据为样本,对BP神经网络进行训练,考察了网络结构(隐含层数、隐含结点数议及学习率η和动量参数α对收敛精度与收敛速度的影响,提出了稳定区的概念和多输出网络分割的思想,并给出了得到较好收敛速度与精度的学习方案。
Artificial Neural Network (ANN) was trained using biological fermentation data as samples.The effects of ANN structure(Hidden Layers Numbers & Units number in each Hidden Layer), learn rate ηand momentum constant α,on learn precision and speed were studied in details.We proposed the conception of stable area & multi-output network division, and provided optimized methods of Back-propagation (BP) training.
