IBM’s Supercomputer Competes in Jeopardy
IBM’s newest innovation, named Watson, is competing towards Jeopardy greats Ken Jennings and Brad Rutter. Evidently, that is extraordinarily spectacular. Not solely does the supercomputer give right solutions, it additionally tells the viewers how certain it’s of the reply. Oh, and it listens to what the host says and might perceive it. Nonetheless not impressed? Watson can perceive nuances of human speech, equivalent to puns and jokes.
That is proper. He understands jokes and puns. Watson does this by working 1000’s of algorithms on the questions it receives, and as a substitute of doing them sequentially (i.e within the order he receives them) he does all of them on the similar time, after which he compares the solutions and decides which is finest, at which level he attaches a proportion to how certain he’s. Watson makes use of VAST shops of literature and random information to collect its solutions from, and as time goes on and he encounters extra info, the quicker he will get and the higher he will get at discovering solutions. The expertise that IBM constructed Watson on is being known as “DeepQA” (do not learn too far into that, you pervs.)
The supercomputer is powered by 10 racks of IBM POWER 750 servers working a Linux distro, makes use of 15 terabytes of RAM (a normal private laptop has 4-8 GIGAbytes), and has a mind that’s composed of two,880 processor cores that may function at speeds as much as 80 teraflops (to place that into a little bit perspective, a lot of the computer systems available on the market immediately have 2-4 processor cores). The system is completely self contained (not linked to the Web) and might course of the over 2 million pages of knowledge in its reminiscence in lower than three second. Fairly frankly, I am impressed. And you have to be too. And sure, I referred to the pc as he.
