If you feel like you have the world's greatest recommender system, you should enter the NetFlix challenge for improving their movie recs. In addition to the possibility of winning a lot of money and achieving fame, you also get an order-of-magnitude larger data set for this task than has been available to date. (Note that in order to win, you have to improve performance over their system for 10%, which is a steep requirement.) I'll offer an additional reward: if you do this using NLP technology (by analysing movie information, rather than just the review matrix), I'll sweeten the pot by $10.
How is ethics like logistic regression?
