Score-Based Perspective: From EBMs to NCSN

This chapter traces the score-based view of generative modeling, moving from energy-based models (EBMs) to score-based generative models. It introduces denoising score matching and the use of multiple noise levels (NCSN), and closes with a comparative view of NCSN and DDPM.

Chapter 3 of The Principles of Diffusion Models.
