Even without customized image operators such as convolutions, ViTs can yield competitive performance when properly trained on massive data. However, the computational overhead of ViTs remains prohibitive, due to stacking multi-head self-attention modules and else.

The discrete image tokens are encoded from a learned Vision-Transformer-based VQGAN (ViT-VQGAN).Current image-to-image translation methods formulate the task with conditional generation models, leading to learning only the recolorization or regional changes as being constrained by the rich structural information provided by the conditional contexts. In this work, we propose introducing the vector quantization technique into the image-to-image translation framework. The vector quantized ...一、改进点： 1.stage1（image quantization ViT-VQGAN）： 基于ViT的VQGAN encoder。 基于VQGAN做了从架构到码本学习方式的多种改进——>提升了efficiency和reconstruction fidelity. 包括logits-laplace loss，L2 loss，adversarial loss 和 perceptual loss. 2.stage2（vector-quantized image modeling VIM）： 学习了一个自回归的transformer，包括无条件生成/类条件生成/无监督表示学习。
