Cold Diffusion: Inverting Arbitrary Image Transforms Without Noise
- ggm 4y agoShame neither a Pons, nor a Fleischmann are on the author list. I love how people can intrude contextual puns and jokes into paper titles.
- MathYouF 4y agoAfter an excellent all day workshop at CVPR this year explaining diffusion in more detail, it seemed pretty clear that any noise function could be used. I'm not sure if it should have been obvious, but I felt this paper coming from a mile away after seeing that. I wonder to what degree certain parts of diffusion dictate using certain noise functions, and how much this paper truly challenges how we understand them. Cool to see it was researched. Next idea: it seems like a lot of steps could be skipped by using things like momentum during the inference time. I'm sure OpenAI has already implemented several clever tricks like that in production for DallE. I'm working on (various, non-diffusion) methods for 2D drawing to 3D output right now.
