Psychologist Beating Math Nerds in Race to Netflix Prize
s1d writes "An almost-anonymous British psychologist named Gavin Potter has suddenly risen to the top of the Netflix prize charts. With his very first attempt, he got a score which took the BellKor team seven months to reach. Currently at a score of 8.07, he has only five teams ahead of him now in the race for the ultimate Netflix algorithm. 'Potter says his anonymity is mostly accidental. He started that way and didn't come out into the open until after Wired found him. "I guess I didn't think it was worth putting up a link until I had got somewhere," he says, adding that he'd been seriously posting under the name of his venture capital and consulting firm, Mathematical Capital, for two months before launching "Just a guy." When he started competing, he posted to his blog: "Decided to take the Netflix Prize seriously. Looks kind of fun. Not sure where I will get to as I am not an academic or a mathematician. However, being an unemployed psychologist I do have a bit of time."'"
that had an undergraduate degree in psychology, a masters degree in operations research that after being well employed for a number of years -- "In 2006, he left his job at IBM to explore the idea of starting a PhD in machine learning, a field in which he has no formal training. When he read about the Netflix Prize, he decided to give it a shot -- what better way to find out just how serious about the topic he really was?"
The summary makes 2 references to Gavin Potter being a psychologist, but it ignores the part of the article that notes he has a master's degree in operations research. This is very much an OR problem. Still, it is impressive that he has been able to do as well as he has considering his competition. Good luck to him!
He might be a psychologist, but his venture firm is named Mathematical Captital, after all. His partners appear to have advanced degrees involving mathematics.
