How to increase loss

vision
1

Hello

I am trying to reconstruct Sinogram.

However, the loss decreases so quickly that the psnr converges at 31 and no longer increases.

So I want to improve psnr by slowing down the loss.

How can I increase loss and is my method correct?

Based on your description it seems you are calculating a specific loss while caring about the PSNR, which is not represented in your loss.
I don’t know if slowing down the convergence would increase the PSNR, so could you explain this assumption a bit more and why this would be the case?
Without knowing details about your use case I would guess the better approach would be to track some kind of information of the PSNR in the loss.

Thank you for reply I concentrate my psnr code

Thank you ptrblck
