The race to the finish of the Netflix grand prize is in its final week. As it stands right now the leading team for the final grand prize is BellKor's Pragmatic Chaos.
The leading team is a group effort of a few teams' combined entries. They use a number of machine learning techniques to arrive at their movie rating prediction outcome.
The combined effort team stands to win $1,000,000 for their efforts. That is unless someone can unseat them before the end of the 30 day challenge which ends July 26th.
