VQDiffusionScheduler VQDiffusionScheduler converts the transformer model’s output into a sample for the unnoised image at the previous diffusion timestep. It was introduced in Vector Quantized Diffusion Model for Text-to-Image Synthesis by Shuyang Gu, Dong Chen, Jianmin Bao, Fang Wen, Bo Zhang, Dongdong Chen, Lu Yuan, Baining Guo. The abstract from the paper is: We present the vector quantized diffusion (VQ-Diffusion) model for text-to-image ge
