Classification: CPC G | IPC G

Claim 18:
19. The system of claim 17, wherein the training further comprises:
processing the ground-truth output example using a trained feature generation neural network to obtain features of the ground-truth output example, wherein the trained feature generation neural network is a pre-trained neural network that takes a waveform as input;
processing the predicted output example using the trained feature generation neural network to obtain features of the predicted output example; and
determining a third gradient with respect to the feedforward parameters to minimize a perceptual loss that depends on a measure of difference between the features of the ground-truth output example and the features of the predicted output example, and wherein determining the update to the current values of the feedforward parameters comprises determining the update based at least in part on the third gradient.
