UnverifiedImproved samplers such as DDIM can reduce the number of denoising steps for diffusion models to tens of steps.79% similarUnverifiedTraditional diffusion models are based on DDPM theory; inference typically requires 20 to 50 denoising steps, and the process is unidirectional and closed, unable to incorporate external knowledge.77% similarUnverifiedInference in diffusion models is an iterative denoising process that typically requires dozens or even hundreds of timesteps and is particularly sensitive to numerical errors.72% similarUnverifiedThe introduction of DDIM (Denoising Diffusion Implicit Models) in 2021 significantly accelerated the sampling process, reducing the number of sampling steps to 20–50.70% similarUnverifiedThe 2020 DDPM paper laid the foundation for modern diffusion models, after which Latent Diffusion Models significantly reduced computational costs by performing the diffusion process in a compressed latent space.69% similar
