Abstract

The present application relates to a method for training a signal denoising model, a signal denoising method, and a device. According to the present application, the method includes: performing stage-by-stage denoising training on a multi-stage network based on training signal data corresponding to the multi-stage network, to obtain a signal denoising model, obtaining, when a current stage subjected to the stage-by-stage denoising training is not a first stage, a loss value of a current-stage network based on training signal data corresponding to the current-stage network, and after gradient descent is performed individually on the current-stage network based on the loss value, performing, based on the loss value, gradient descent jointly on current multiple stages of the network that have undergone the gradient descent individually.
