I don't understand your connection between lightfm and the youtube paper...

  they are hybrid in the sense that gather signals from not just features or user activity, yt paper uses embeddings from search and views, so its more of a mixed model than a pure one content based or a pure collaborative filtering

    ok, I see, you are making the connection on basis of hybrid characteristics. Since you're familiar w/ the youtube paper, I've been wondering this question: How do they get vectors out of the softmax?
