Main point: bigger GANs like BIGGAN don't let you train with your own images because they're so expensive to train. So everyone is creating art from the same pretrained model (and it'll presumably all look somewhat similar)
- gwern 8y ago> bigger GANs like BIGGAN don't let you train with your own images because they're so expensive to train. I don't think we know that. They're super-expensive to train from scratch, but there have been few experiments investigating GAN transfer learning. In my own very simple personal experiments, when I trained a ProGAN on one anime character's faces and then retrained it on a second anime character's faces (Asuka->Holo), it adapted very quickly and successfully; so I suspect that the released BigGAN models might be retrainable with a tiny fraction of the resources. Training on your own photos should be doable. The real reason that everyone is using the BigGAN models and not retraining them is because, well, there's no way to retrain them! The BigGAN source wasn't released, and the only implementation so far doesn't support loading them and retraining. So you can't do it, no matter how much you want to, unless you are so good at TF/PyTorch that you can program it yourself. Which apparently no one has so far.
