Cosine-Beta Schedule for Denoising Diffusion Models
Denoising Diffusion Probabilistic Models (DDPMs) are quickly taking over the world, especially since Dall-E 2 and Midjounery came out. It is quite interesting how powerful they are considering they are based on Markov Chains which were introduced all the way back in 1906. Diffusion models are based on a forward process and a backward process. In the forward process, noise is added to the dataset in incremental steps through a Gaussian distribution....
