The wavelet neural network is a kind of neural networks,which can closely combine wavelet theory with neural network theory,and avoids the blindness of framework designs for BP neural networks and the problem of nonlinear optimizations,such as local optimization.So it can greatly simplify the training of neural networks.It has good abilities of function learning and dissemination with a vast range of prospects for application.Applying the distributed training grade prediction system is realized by mix-coding technology,ac...
