There's a lot of GAN monsters here. One of the big improvements from StyleGAN->2 was the introduction of Perceptual Path Length Loss (PPL). Has the author thought about adjusting that? Additionally there is StyleGAN2-ADA (recent) which deals better with smaller datasets (I'm not sure how big this dataset is but I'm sure it isn't as big as ImageNet). I'd imagine this would help significantly because most of the monsters are having issues with the body and multiple people, so there's probably not as many samples with that feature in the dataset. I'd be interested to see what improvements these would make.

PPL was one of the problems in scaling up StyleGAN2. It contributes to the over-regularization that made diverse images impossible to learn. There might be some very weak value of PPL which is beneficial (probably the optimal value of the PPL regularization is not exactly 0) but when the runs take a month or two, it's not easy to experiment with them!

The dataset is actually ~3x bigger than ImageNet, FWIW.

Oh that is very interesting. Thanks. Do you know anything else about the dataset? I was looking at the link for some quick stats and didn't see them. I'm curious if there are metrics to support or disprove my hypothesis about body features. If so ADA would still help because there isn't an even distribution of the features.

I included the basic stats in https://www.gwern.net/Faces#extended-stylegan2-danbooru2019-... and links to the writeups for the individual datasets.

I feel like I'm looking at a painting from Salvador Dali on some of these...

These are the ones I actually want to see. You call them Monsters I call them AI creatives.

I specially like this one.

I get migraines with visual hallucinations, and while I don’t get kaleidoscopic hallucinations, this kind of reminds me of what I’ve read about them.

Since we're sharing our favorites, I think this one would make for a neat magical girl transformation: https://thisanimedoesnotexist.ai/results/psi-1.9/seed6930.pn...

And this one https://thisanimedoesnotexist.ai/results/psi-1.0/seed17653.p... is less monster, and more like /r/badwomensanatomy :)
