I started drawing up a very quick attempt at this netflix challenge
using Self-Organizing Maps and treating the data in a similar way that
my university research group predicts assemblages of species in
countries around the world. I suspect it will do alright but not be
the best - I don't have the time to seriously attempt the competition.
If anyone else in sl4 is playing around with the challenge and wish to
talk about the data/ideas/etc then feel free to send me an email.
