matlab小波去噪程序，包含语音信号，和一维吸信号(wavelet denoise matlab code，including wav signal and one d signal。)

Backpropagation, an abbreviation for backward propagation of errors , is a common method of training artificial neural networks used in conjunction with an optimization method such as gradient descent. The method calculates the gradient of a loss function with respects to all the weights in the network.
