【摘要】 BP网络是人工神经网络中应用最广的网络模型,为了改善BP算法易陷入局部极小点的缺点,提出一种基于MPGA(多种群遗传算法)的改进BP网络。数值仿真结果表明:经多种群遗传算法优化的BP网络和遗传算法优化BP网络以及传统BP网络相比较,在预测精度方面有了改善。更多还原

【Abstract】 BP network is the most widely used network model in artificial neural network., In order to improve the disadvantage of BP algorithm, a new improved BP network based on MPGA(multi group genetic algorithm) is proposed, The numerical simulation results show that the optimized BP network based on multi population genetic algorithms have improved the prediction accuracy of BP network.更多还原
