a more useful paper on netflix prize (and how LSI-like techniques helped the winning team)

I added the following paper to the collaborative filtering readings:

This is a paper from IEEE Computer last year, written by Yehuda Koren--the same guy who wrote the CACM paper. Unlike the CACM paper that focuses just on temporal concept drift--that helped them vault over the last little percentage--this one talks about LSI-like techniques for doing collborative filtering, and how they allow him to combine multiple sources of feedback.

Certainly worth reading as most of the ideas he is using are in the epsilon-neighborhood of things we have covered in the class (and thus should make you feel warm and fuzzy about your knowledge state ;-)
