WebAug 5, 2024 · The correct way to SSIM as training loss is as follows. SSIM is defined for positive pixel values only. To be able to compute SSIM on the prediction of your network and the (positive only, and preferrably normalized) input tensors, you should restrict your network's top layer to only output numbers in the range [0, inf] by using a "softplus ...
