IBM moves closer to creating chips based on the brain

ibmIBM said today that it has made significant progress toward developing a computer that simulates and emulates the brain’s abilities to sense, perceive, interact, and recognize.

The computer does this by imitating the brain’s low-power energy consumption and compact size, and it has an intelligence level that approaches the smarts of a cat. Big Blue will announce the development at the SC 09 supercomputer conference in Portland, Ore.

IBM Research’s cognitive computing team has made progress with what it calls “large-scale cortical simulation” and has created a new algorithm, or math formula, that synthesizes brain-like data. Both of those steps are necessary in creating a brain-like chip. We wrote about this effort, headed by Dharmendra Modha, last year when IBM announced its start.

The scientists at IBM Research-Almaden and the Lawrence Berkeley National Lab have performed the first near-instantaneous simulation of the brain. The simulation is more sophisticated than that of a cat’s brain and has a billion “spiking neurons” and 10 trillion individual learning synapses, which are akin to the connections between brain cells.

And, working with researchers from Stanford University, IBM scientists have developed an algorithm that exploits the Blue Gene supercomputer to measure connections within the human brain without being invasive. The technique uses magnetic resonance diffusion weighted imaging to map the way the brain is wired. By doing this, IBM has taken a step toward unraveling how communications happen within the brain.

The advances will provide a way to study how the brain works and to move closer to the goal of building a chip that simulates that. If it can do so, and that is of course a big if, then IBM may depart from the way that computing has been done since John von Neumann figured out how to build computers back in the 194os.

The researchers believe that as the amount of digital data grows, and the world becomes more instrumented and interconnected, there will be a need to create faster, more efficient computing systems with a higher level of intelligence than those we use today. For all the sophistication of today’s supercomputers, they can’t do a lot of things, such as recognizing patterns, as well as humans do. Other researchers, such as Numenta founder Jeff Hawkins agree with that and are also trying to create brain-like computers.

“Learning from the brain is an attractive way to overcome power and density challenges faced in computing today,” said Josephine Cheng, IBM Fellow and lab director of IBM Research – Almaden, in a statement. “As the digital and physical worlds continue to merge and computing becomes more embedded in the fabric of our daily lives, it’s imperative that we create a more intelligent computing system that can help us make sense the vast amount of information that’s increasingly available to us, much the way our brains can quickly interpret and act on complex tasks.”

The IBM team built a cortical simulator that incorporates a number of innovations in computation, memory, and communication as well as sophisticated biological research. After completing the first part of the research, IBM and its university partners were given a $16.1 million grant from the Pentagon’s Defense Advanced Research Projects Agency to create a prototype chip that can simulate the brain’s functions. The idea is to create something that is as smart as a mammal.

The overall research team includes researchers from several of IBM’s worldwide research labs and scientists from Stanford University, University of Wisconsin-Madison, Cornell University, Columbia University Medical Center and University of California- Merced.

    This is absolutely and utterly false. I mean, it's so totally untrue I can't imagine IBM claiming it or Dean reprinting it.

    Pause to read the link. Aha. Cortical simulation. Assembling computational resources that can be said to approach the computational resources of a brain has little to do with demonstrating intelligence. The IBM cortical simulation will not in fact be able to perform any "intelligent" activities, because we still don't understand how intelligence works at a low level, so IBM's simulated synapses will just not implement any useful pragmatics.

    Our current technology is frankly unable to demonstrate the intelligence of a housefly, much less something with an actual brain.

    Among the things that animals do that we can't program:

    - physically coordinate a complex body with hundreds of muscles and bones. We couldn't even get a cat-shaped robot to walk on its own: it's too complicated compared to any mobile robot yet attempted. But even a mouse can run and climb more effectively than any robot, and I suspect a housefly can do better aerobatics than any drone.

    - navigate an unknown 3D space in real-time. Current robots are very slow and incompetent if the space has not been fully mapped in advance, or if it isn't quite flat. There's a reason these DARPA competitions tend to leave a trail of broken and lost disabled vehicles along the track....

    - recognize predators and prey; evade the first and pursue the latter

    - recognize any kind of unknown objects except in very limited and dumb ways

    - find warm sunny spots in which to sleep (well, OK, this can in fact be programmed :-)

    Why are you so critical Anon? This is a big anticipated step forward. Wait until 'Memristors' are fully implemented, then things will really move forward with A.I.
  • What I like here is the fact that the design, features, functions and capabilities, as we know them, of human brain are being used intentionally and once again as a foundation for technological evolution. For me the story is larger and the social value, if true, very significant. If we could ascertain, as objective fact, that we do look "within" to manifest "without" then it would be wise to embrace this design-process as a natural, mind-motivated human-tech evolutionary process.

    What interests me is this idea of an “ecology-of-mind" as an operating and subterranean technology development movement and what appears to be an innate motivation of the human mind to use itself - to mirror, project and build - within certain specifically applicable "spheres" of technology, e.g. social networking, Internet, mobile, distributive systems, infrastructure design, org-design, AI and more.

    The evolutionary purpose of this, I have no doubt, is to most fully optimize, over human generations of time, the quality of global human connectivity. IMHO, our unique working brains, as our YOUnique minds, and as a global system of minds, are laboring - for the most part unconsciously - towards building technologies that allow us to find optimal "Mind-Fits." The purpose of this motivation should be obvious. The "how" if it all; predicting future technologies assuming such a theory; and the incredible bottlenecks to optimizing our best Mind-Fit connections along the way makes this a very interesting meta-pattern to observe, assess, write about, and act on with intention.

    Totally agree with Anon. The announcement and paper is all about numbers and how fast their machine runs. While that could be important they have no theory to go with it. It is like trying to build a flying machine by replicating feathers rather than understanding the principles of aerodynamics. I doubt this system can solve pattern recognition or computer vision problems anywhere near today's state of the art algorithms.

    Everything will be all right,I am behind you.That’s something,That's what I was thinking.Brilliant idea.iphone club

    For all the wary out there your negativity towards A.I. is understandable and I don't blame you. So many starts and stops, fits and fragmantations, ups and downs, unsolvable solutions in the cest pool of A.I. over the years has led to limitations or just plain dead ends. This is because the A.I. legacy has approached this incredibly difficult problem totally the wrong way all these years, trying to emulate the behavior and intelligence of the mammalian brain from a computer science POV without having a great brain theory and having a great understanding of neuroscience particularly cortical/thalamus science to back it up. Now that computer science has kowtowed to the absolute study and starting point of neuroscience accounting for their historic blind sighted fallacy, the new era of Cortical computing can shed from the old A.I. cocoon and take flight in a whole new bright future.
