一、BP网络介绍自从1985年,Rumechere和Mclellend领导的PDP研究小组提出多层前馈网络的误差反传训练算法(BP网络)以来,BP网络已成功地解决语音识别、过程监控、信号处理、预测、测井、油田地震等工程领域中的大量问题,各种有关BP网络应用成功的文章大量涌现在各种学术会议和刊物上。BP网络 I. INTRODUCTION TO THE BP NETWORK Since the PDP research team led by Rumechere and Mclellend proposed the error back propagation training algorithm (BP network) of multi-layer feed-forward network in 1985, the BP network has successfully solved the problems of speech recognition, process monitoring, signal processing, Prediction, well logging, oilfield earthquakes and other engineering fields. A great variety of articles on the success of BP network applications have emerged in various academic conferences and publications. BP network
