Noise Schedule
Definition
A noise schedule defines the disturbance strength over the steps of a diffusion model.
The predetermined sequence of noise strengths over the time steps of a diffusion model. It determines the forward process and influences the learning or numerical solution of the backward process.
Simply explained
A schedule determines when and how much noise is added and which backward steps the model must learn.
Why it matters in practice
Helps realistically assess model quality, limits, and technical decisions.
Example from business
An image model distributes noise steps so that information is controlledly destroyed and reconstructed.
Limits and pitfalls
- Compare schedules independently of parameterization, sampler, and training objective.
Origin & history
Denoising Diffusion Probabilistic Models popularized linear and later improved schedules.
Use in mid-sized companies
- Possible application: An image model distributes noise steps so that information is controlledly destroyed and reconstructed.
