One thought on “New blog post on momentum

  1. Hi,

    I was wondering if anyone had worked their way through the blog post?

    I was looking at the section “First Steps: Gradient Descent” and for some reason I can’t seem to derive the same expression as in the blogspot for the equation:
    x_i^{k+1}= x_i^{k} ….

    Specifically the second term ” -alpha…”. I tried to develop the whole thing but can’t seem to find the exact same thing as presented here.
