Noise Schedules for Diffusion Probabilistic Models
2022 · Comparing noise schedules for diffusion-based image generation.
Diffusion Probabilistic Models (DPM) gained attention recently due to their mathematical properties and competitive performance on image generation tasks. A major ingredient in DPMs is the noise schedule which dictates the noising process that a denoising model must learn to undo. We explore and compare different choices for the noise schedule in a common framework on a non-standard dataset.
