Netflix Prize

Sou um grande fã de cinema. Por isso, acho bastante interessante este desafio da Netflix:
"We’re quite curious, really. To the tune of one million dollars.

Netflix is all about connecting people to the movies they love. To help customers find those movies, we’ve developed our world-class movie recommendation system: Cinematch. Its job is to predict whether someone will enjoy a movie based on how much they liked or disliked other movies. We use those predictions to make personal movie recommendations based on each customer’s unique tastes. And while Cinematch is doing pretty well, it can always be made better."
Prémio de um milhão de dólares para quem melhorar o sistema de recomendações da Netflix, empresa de aluguer online de DVDs.

No New York Times (via Digg):
"About 18,000 teams from more than 150 countries — using ideas from machine learning, neural networks, collaborative filtering and data mining — have submitted more than 12,000 sets of guesses. And the improvement level to Netflix’s rating system is now at 7.42 percent."
