Prize Over?
Haven't posted in a while, but last call for the Netflix Prize has been out for nearly a month. There may finally be a winner. I'm wondering if the site will be shut down after that or if it will keep going. They would of course have to come up with some new reasoning for the project, since they've already got a 10% improvement over their algorithm.

Project Over
I finished up my project last Monday with my senior seminar presentation.
I wasn't able to investigate everything I had planned on, mostly because it took longer than I expected. I may try and work on it after I get out of school if I have time.
I did try a couple modifications to BRISMF. First was using a user based neighborhood correction instead of item based. This gave a little improvement, but pretty much trivial at the cost of about 4 hours additional prediction time. I tried a couple of other things, but to no better success.
But I did end up with a good idea of how these algorithms work, and how recommender systems in general behave. Hopefully I can work a little more on this later.
