Netflix Prize: First Entries
The first few entries in the Netflix prize are up. The Netflix prize is 1 millions $ given to the first person to be able to improve by 10% the Netflix recommender system according to RMSE (Root Mean Square Error) metric. People asked me if I would participate. Well, no I will not be involved as a participant, but I will be an observer.
I got an email from Anno Langen who is participating (under the pseudonym Actual Proof) and he is currently in eigth place using an algorithm from my Scale And Translation Invariant Collaborative Filtering Systems paper. Because Netflix is using the RMSE metric, I think that Scale and Translation invariance becomes an important factor.
