Diffusion models are widely used for visual generation and have recently become important in pixel-space world models. This note introduces EDM (Elucidating the Design Space of Diffusion-Based Generative Models), a continuous-noise diffusion formulation that differs from classic DDPM. I study EDM because it is used by DIAMOND, one of the world models in my research.

Box is a cloud storage service, similar to Google Drive or Dropbox, that is widely used by universities. My school (UC Davis) provides its community with Box storage, including unlimited storage capacity and support for individual files up to 150 GB (UC Davis ServiceHub policy).

This makes Box a convenient option for storing research artifacts such as model checkpoints, datasets, and other large files.
