In case you are wondering, this paper proves that, in general, diffusion models do not define optimal transport maps. The proof is not straightforward though (diffusion maps are optimal maps in 1D, for radial measure and for Gaussians ...) cvgmt.sns.it/media/doc/pape…

“Grothendieck was working on the foundations of algebraic geometry seven days a week, twelve hours a day, for ten years”. - David Ruelle ift.tt/MDWa74I

"Nobody else took what I was doing seriously, so nobody would want to work with me. I was thought to be a bit eccentric and maybe cranky" Peter Higgs, the physicist who discovered the theoretical mechanism explaining the origin of mass in the universe, has passed away today.
Why do we require Jacobi identity to be satisfied for a Lie bracket? In the process, we also understand intuitively why tr(AB) = tr(BA) without matrix components. Watch now: youtu.be/gj4kvpy1eCE
