In this video you'll learn about the Unadjusted Langevin Algorithm, and how it can be used to sample new data. This method was a precursor to what we now call "Diffusion models", which are just an annealed version of this algorithm.

Here is all the code used to produce the video, including the code of the "Implementation" chapter:
