摘要

Figure 1. Synthesized samples on various datasets, including FFHQ (1024 2 and 256 2 ), LSUN Church (256 2 ), LSUN Bedroom (256 2 ), LSUN Cat ( 256 2 ) and CIFAR10 (32 2 ). All these samples are generated from a 64 2 noise except CIFAR10 from 16 2 , while conventional diffusion models can only start from a noise with the same dimension as the final sample.
