Simple diffusion: End-to-end diffusion for high resolution images

Understand

Currently, applying diffusion models in pixel space of high resolution images is difficult.

• Instead, existing approaches focus on diffusion in lower dimensional spaces (latent diffusion), or have multiple super-resolution levels of generation referred to as cascades.
• The downside is that these approaches add additional complexity to the diffusion framework.
• This paper aims to improve denoising diffusion for high resolution images while keeping the model as simple as possible.
