摘要
通过找出其隐式函数关系,误差反向传播神经网络可以实现输入和输出间的任意映射.采用BP神经网络和瞬态有限元计算,确定了大直径SHPB杆弥散效应的隐式传递函数,对弥散效应进行了修正,讨论了网络隐层的神经元个数对网络映射的影响.
With the implicit function relation, BP(Back Propagation) neural network can easily realize the mapping between input data and output data. The implicit transfer function of wave dispersion in large diameter SHPB has been determined by using the BP neural network and the dynamic finite element calculation. The dispersion effect has been modified. The effect of neural unit number in network on network mapping has also been discussed.
