In October 2006, the DVD rental company Netflix released more than 100 million user ratings of movies for a competition to predict users' ratings based on prior ratings. The discussion leader was one of two statisticians on a multi-disciplinary team that won a $1,000,000 prize after 33 months by achieving a ten percent reduction in root mean squared prediction error relative to Netflix's current algorithm. Discussion topics may include models with more parameters than observations, contrasting perspectives of statisticians and computer scientists, the role of prizes as a way to advance science, and a race to the finish line that you would not believe in a movie.
