Question about the DownScaleLoss #66

Open Algolzw opened 2 years ago

Algolzw commented 2 years ago

There is no DownScaleLoss in the paper, could we set the param 'lambda_bicubic' to 0?

sefibk commented 2 years ago

It is referred to in sec 4.1:

To provide a reasonable initial starting point, the generator’s output is constrained to be similar to an ideal downscaling (e.g. bicubic) of the input, for the first iterations. Once satisfied, this constraint is discarded.

Note that lambda_bicubic is decreased to 0 relatively fast
