Quick! Someone get John Connor to Crystal Peak while there's still time!IBM wins funding for 'brainy' computer
Thursday, November 20, 2008
NEW YORK: International Business Machines said Thursday that it had won $4.9 million in U.S. Defense Department financing to create computers that mimic the way a brain functions.
The effort, still in the early stages, may lead to machines that can quickly sift through vast amounts of information and arrive at a decision. Confronted with a nonstop flood of new data, computers will have to learn to pick out crucial facts more quickly, said Mark Dean, an IBM vice president.
"The challenge is that computers today are very good at computing, but what we really need is a more efficient way of sifting through information," Dean said.
"Modeling after the way the brain operates might be an effective way of constructing the next level of computing engines."
The grant comes from the Defense Advanced Research Projects Agency, the Pentagon's central research organization, which helped build the Internet. IBM, based in Armonk, New York, said it planned to work with researchers from five U.S. universities on the project.
The company would not say when the advanced computers would be produced because the research is still new. The funds cover the first phase of the project.
The ultimate goal is to build a computer with the human brain's capabilities, though "even a computer with the ability of a rat brain would be a success," said Dharmendra Modha, IBM's lead researcher on the project in San Jose, California.
Modha described the research as "the quest to engineer the mind by reverse-engineering the brain."
"It's a quest like Dorothy looking for the Wizard of Oz," he added. Computers excel at tasks, even daunting ones, when they work in domains with clear rules, like chess. But they do not excel at fuzzier problems, said H.-S. Philip Wong, a Stanford professor who will work on the project. Wong cited the example of how a human devises a mental strategy for finding a car, whose exact location has been forgotten, in a busy parking lot. That task, he said, requires higher-level cognition - sensation, perception, learning and reasoning.
The time is right to pursue cognitive computing, according to Modha, because of advances in computing, nanotechnology and neuroscience.
In neuroscience, for example, there has been a data-driven surge in research on neurons, synapses and neurotranmitters.
But will the brain and its workings, like so much else in biology, prove to be far more complex than foreseen, and thus resistant to the math-modeling of computer science?
That is certainly possible, Modha conceded. But all sorts of insights and new knowledge will be gleaned along the way, he said, leading to new computing products, software and sensors. IBM, he half-jokes, should someday stand for Intelligent Business Machines.
