ImageNet64, classifier guidance ADM-G is worse than ADM regarding FID, but better than ADM regarding IS #119

Hi, can anybody share the FID of ADM-G on ImageNet 64? I get a worse FID than the unconditional ADM

Hi @unixpickle , thanks for the work and code.

with the pre-trained model, I tested the conditional ADM-G and ADM on ImageNet64 with 100 sampling steps and dropout 0.1. ADM gets FID 3.25 (looks normal)

but the FID for ADM-G is strange: ADM-G scale 0.3 = 4.14 FID ADM-G scale 1 = 7.22 FID ADM-G scale 3 = 13.67 FID

But ADM-G achieves higher IS than ADM.

Is this normal in your experiments?

Thank you very much!
