Question about the defintion of Pruning loss
loss = torch.sum(torch.abs(noisy_img - img_tensor)) I hope to know why define pruning loss like above and the reason for minimizing this loss.
First, it's a back-propagate-able loss. Second, we use it to evaluate channels' sensitivity for the content region noises. Please refer to the paper Sec. 3.1.2 for more details.
