WebPrevious approaches to diffusion probabilistic models fixed the diffusion process; in contrast optimize the diffusion process parameters jointly with the rest of the model. This turns the model into a type of VAE [Kingma and Welling, 2013, Rezende et al., 2014]. This is enabled by directly parameterizing the mean and variance of the marginal q ... WebA VAE is a variational autoencoder. An autoencoder is a model (or part of a model) that is trained to produce its input as output. By giving the model less information to represent the data than the input contains, it's forced to learn about the …

They define a Markov chain of diffusion steps to slowly add random noise to data and then … WebSep 27, 2024 · Abstract: Diffusion Probabilistic models have been shown to generate state-of-the-art results on several competitive image synthesis benchmarks but lack a low …
WebDiffusion models are bar none the best option for sr if you care about quality and dont mind the increased inference time. There really is no other option for multimodal sr. Gans do good if your input space is constrained. Likelihood models seek the mean and produce crappy outputs as a result. WebAug 15, 2024 · DiffuseVAE is a novel generative framework that integrates a standard VAE within a diffusion model by conditioning the diffusion model samples on the VAE …
