Denoising Diffusion Models in Deep Learning

Generative models that learn to reverse a gradual noising process, starting from pure noise and iteratively denoising toward a sample from the data distribution. Students learn the forward and reverse diffusion processes, noise schedules, the denoising training objective, and how sampling trades iteration count against quality.

What are Diffusion Models?

Diffusion models constitute a latent variable generative framework where image generation is defined by reversing a fixed forward Markov chain that gradually adds Gaussian noise to data until it reac…
