Training log #13
Comments
Dear, authors, I have another question about the FID evaluation. If I understand correctly, the FID provided in the code is computed on the training set? (i.e. real and reconstructed images are both for the training set) The details can be found in the following scripts: If this is true, does it make sense to report FID on the training set? Thanks for your time !! |
Hi, thanks for your interest in our paper and code! I shall answer your questions in order:
It makes sense in this setting because in our experiments we cared about evaluating raw reconstruction quality, which is impacted by training stability and how many codes are used, among other issues - what we were trying to address with our VQGAN changes, not generalisation. As a side note, in later experiments we found that DiffAug helps with generalisation quite a bit. |
Thanks for your reply !!! |
Dear authors,
Thanks a lot for sharing the code, which is quite clean and easy to read !!
I plan to train the model from scratch.
As the training takes ~10 days (c.f. issue 11), I am wondering whether it is possible to share your training log corresponding to the experiments of Lsun churches (VQGAN and Absorbing Diffusion sampler).
Finally, in the paper Sec.4.4, you mentioned that leveraging Diff Aug +$\lambda_{max} = 1$ leads to better performance. However, in the provided config, if I understand correctly, the diff aug is set to False.
