摘要
结合BP网络在承压水漏斗动态规律研究中的应用,对BP网络模型研制中监控样本的设置、样本数据的规范化处理、网络权重和阈值的初始值的确定、训练函数的选择等问题进行了研究与实践,所提出的方法及有关结论具有普适性,为BP网络的广泛应用提供了可借鉴的方法.
Based on the application of BP network in the study of the dynamic rules of the confined water cones, several issues in development of BP network model including setting of monitor sample, normalized treatment of sample data, determination of the initial value of network weights and thresholds, and selection of training functions were investigated and practiced. The proposed methods and conclusions have general applicability, and provided reference methods for broad application of BP network.
