Webmodels in short. DPMs can be viewed as a type of variational autoencoder (VAE) [Kingma and Welling, 2013, Rezende et al., 2014], whose structure and loss function allows for … Webdiffusion models have close connections with other research area, such as robust learning [101, 156, 205], representative learning [1, 131, 232, 249] and reinforcement learning [92]. However, original diffusion models still suffer from a slow sampling procedure, which usually requires thousands of evaluation steps to draw a sample [78].
