WebFeb 20, 2024 · The generative modeling scheme of PIDM is based on the Denoising diffusion probabilistic model [6] (DDPM). The general idea of DDPM is to design a diffusion process that gradually adds noise to the data sampled from the target distribution y0 ∼ q(y0), while the backward denoising process attempts to learn the reverse mapping.

WebDenoising diffusion models (DDMs) have emerged as a powerful class of generative models. A forward diffusion process slowly perturbs the data, while a deep model learns to gradually denoise. Synthesis amounts to solving a differential equation (DE) defined by the learnt model. Solving the DE requires slow iterative solvers for high-quality generation. …
