It uses an autoregressive model to predict codes for a pretrained VQGAN, doesn't it?
Doesn't Stable Diffusion's autoencoder also use an adversarial loss? Otherwise wouldn't it suffer the typical blurring problems well known to MSE?
- GaggiX 4y agoYes, all the autoencoders you see used in practice have adversarial loss + MSE + perceptual loss, the VAE used with Stable Diffusion also uses KL regularization, while VQGAN uses all other losses to make use of the codebook.
