Upsample Guidance: Scale Up Diffusion Models without Training
We demonstrate that upsample guidance can be applied to various models, such as pixel-space, latent space, and video diffusion models.
Resolution Chromatography of Diffusion Models
In this paper, we introduce "resolution chromatography" that indicates the signal generation rate of each resolution, which is very helpful concept to mathematically explain this coarse-to-fine behavior in generation process, to understand the role of noise schedule, and to design time-dependent modulation.
Unsupervised Discovery of Semantic Latent Directions in Diffusion Models
Despite the success of diffusion models (DMs), we still lack a thorough understanding of their latent space.
