IBMs Supercomputer Watson defeats Humans in First Contact

Erinnert ihr euch noch an meinen Post mit der etwas zu langen Überschrift über Watson, den Supersprachcomputer von IBM der sich in Jeopardy gegen die Besten der Besten der Besten durchsetzen soll? Letze Woche gab es die erste Probe und Watson hat die beiden Kandidaten vorab und erst einmal nur inoffiziell vom Allerfeinsten weggeputzt.

Watson, named after IBM’s founder, is one epic supercomputer. To handle the formidable task that competing on Jeopardy! presents, IBM spent years constructing a computer with 2,800 Power7 cores. That power is absolutely necessary–a single-core CPU, like in many modern computers, takes about two hours to come up with an answer to a standard Jeopardy! question, rather than the three-second average Watson currently boasts.

A lot of the challenge in creating an algorithm that can answer Jeopardy! questions lies in the questions themselves–the language used in these questions is hardly ever simple, often incorporating wordplay, riddles, and irony–but there’s an additional problem in the addition of risk. In a split-second, a competitor must assess confidence in the question, weigh that confidence against the penalty of getting it wrong, and decide if the question is worth answering based on those factors. That’s an intuitive effort for a human, but Watson had to be programmed with some incredibly complex reasoning to be able to do the same thing.

Man bedenke, die Konfiguration ist noch nicht perfekt, dennoch sind fast alle seine Antworten richtig und für eine kleine Spitze gegen die Kontrahenten “let’s finish this category” war auch noch Zeit. BTW ich liebe sein Pivot-Avatar! via engadget, nerdcore, popsci
