Nice! That looks very promising. Given how similar PLSA and PLCA are to this, I imagine the steps to trying this are:

  1. Implement using NMF
  2. Try PLCA (cause we care about time series)
  3. Incorporate face priors into PLCA

Obviously 1 is the focus, but I think 2 and 3 would be the next steps if we had time
