How useful was the Netflix Prize challenge for Netflix?
I don't get why they wanted to go all out on AI for this. I use Netflix, and a simple algorithm would already be an improvement:<p>- If I watched a movie and gave it a thumbs down, don't recommend it<p>- If I watched a movie < 1 month ago, don't recommend it<p>- If I browsed over a movie 50 times, read the info, and still didn't play it, stop recommending it.<p>- If I watched the last episode, remove the "new episodes" banner.<p>WTF
