I really can't seem to find the paper metioned at 34:00 by John Healy: could someone point me to it, give me the actual name of the paper, or the full name of the main author?
You are looking for: Generalized Low Rank Models by Udell, Horn, Zadeh and Boyd You can find a copy of the paper here: web.stanford.edu/~boyd/papers/pdf/glrm.pdf It really is a great paper, and I can't recommend it enough!
