基于BtW的和声搜索算法在BP网络优化中的应用
Harmony search algorithm with BtW and application in BP network optimization
摘要
Abstract
Aiming at the problem that the performance of harmony search algorithm is influenced by its parameters while optimizing BP network, an improved harmony search algorithm based on parameters dynamic changes with BtW is proposed and used in BP network optimization, it can improve the convergence rate and accuracy of BP network. According to the characteristics of parameters, nonlinear function transform method decided by BtW is adopted, meanwhile PAR and BW are dynamic adjusted. Then the connection and bias weights of BP network is optimized by the improved harmony search algorithm. The experimental results show that, this method has effectively improved the performance of harmony search algorithm in BP network optimization and has enhanced the training speed and accuracy of BP network.关键词
