Topic Modeling for Data Preprocessing notebook produces incorrect results.

[warrenrross]

I am running through the notebook as written on GitHub and the recommendation engine at the end of the notebook is giving me the same results as the beginning of the notebook (different from the results your notebook previews). You clearly had it set up correctly at some point before saving it. I have been trying to figure out what is going wrong but the data that your preprocessing drops seems to be dropped and from the set that is fed back into the recommendation engine. Please task me with getting better info for you and I'll do what I can.
