Visualizing 1D diffusion. What is a probability flow line?

YouTube • May 13, 2024 • 01:16:59

In this talk, Roger reviewed a notebook where he helped us visualize what goes in inside diffusion and understand what is a 'probability flow'. We will study the diffusion of a 1D data distribution with Gaussian Mixture Models (GMMs). First, we try to gain an intuition for diffusion by looking at diffusion as modeled by an SDE (Stochastic ...
