code link that you get from from bits back coding on that Wilmette that's what we wanted plus a very small error term so what what's nice about this is that it turns an intractable algorithm into a more tractable one so if you wish to directly implement this algorithm it turns out you do have to compute the Jacobian of the flu model and you do have to factorize it in a certain way and so that's that's polynomial time it's better than exponential time but it's still not good enough for high dimensional data and so the
