A Billion Predictions a Day.
WOW! Netflix serves nearly a billion movie predictions a day. That is really amazing! They also collect 2 millions ratings per day. That is a lot of data. I would love to see the back end systems that they use to crunch the ratings. I had heard that it takes them 3 days to generate their forecast model now I know why. You can read more about their technique on forbes.com I wonder how these numbers relate to what the other recommender systems gather. I know what we gather at Sourcelight is not nearly as large as this. I would have thought with all this data they would have released a larger chunk of it for the Netflix prize contest.
