IBM Working on Brain-Rivaling Computer

Posted by ryuzaki0 on from the will-it-get-bored-too dept.

Obdurate writes "The first supercomputers to approach and even surpass the processing power of the human brain are to be built by IBM, under a $184M contract announced by the US Government yesterday. ASCI Purple and Blue Gene/L will be the fastest and most powerful machines built, with a combined capacity equal to the 500 best of todays computers."

      yeah. like calculating the precise angle and velocity to jump in order to avoid a phaser shot that was just fired. Damn but if I could move faster than the speed of light as well as Mr Shatner did (regularly) on Star Trek...

      Not quite...

      A phaser's energy pulse doesn't travel at c--if it did, we'd never see even a little streak in any scale small enough to see the crew or the enterprise. The directed-energy weapon has at least some mass to contain the energy.

      And even if the phasers did move at c, to dodge one you don't need to get out of the way of the ray--you need to get out of the way of the person pointing it. It's much easier to dodge reaction time than the speed of light. ;)

      It's also probably simpler for a brain to calc. the likely target of the phaser, and then NOT to be there, than to try and find the optimum hiding place. Act first, and think in the half-second while your body is going "wow, we're not dead!"

      Actually, you're incorrect here. According to The Next Generation Technical Manual, phaser blasts travel at c, or the speed of light, as a phaser is a directed energy weapon. This corresponds quite nicely to our more mundane LASER, which is a beam of collimated light energy composed of photons. Photons (the particles, not the torpedos) are massless particles that always travel at the speed of light. Beams of energy need not have mass in order to do what they do, but if you ask Einstein, mass and energy are related so the point is somewhat nebulous.

      As you see, it would be impossible for our dear captain to dodge a phaser blast, for to do so he would have to be moving faster than c. I doubt Kirk has a personal warp drive in his back pocket, so this just isn't possible. But if he can't dodge the blast, he'd be dead, and in the words of Phil Farrand of The Nitpicker's Guide, "it'd be a really short show".

    The human brain does more than simple processing. Think about it, the ability to do calculations, etc., is tied into the most ancient (reptilian) part of the brain.

      I think they are taking that into consideration. The ability to do calculations is a very high level function (how many dogs can do it?), and we know computers can do that a LOT faster than us (when was the last time you multiplied a billion numbers in a second?). Its all the autonomous functions of the brain (i.e. vision and speech processing, etc) that contribute to our amazing computation abilities.

      While it's true that the ability of our brain to control hundreds of muscles as well as it does is important, the thing that our brains do the best is pattern matching. It's how we can hear many different people talking and ignore the differences in the way they say 'potato', for instance, to figure out what he or she is saying. It is rather difficult to get a computer to emulate that sort of thing.

    Neurons in adults: 2x10E9 to 5x10E9
    Synapses in adults: 10E14, a few thousand per neuron
    Neuron firings per second: max 2 Khz

    The biggest challenge in comparing brain to supercomputer is the massive connectivity of brain, with 2000-5000 synapses per neuron.

    The total processing speed of ASCII Purple sounds about right for number of neurons in brain times the maximum number of pulses per second per neuron.

    Given there are 10E14 synapses, each one with at least a byte of synpatic weight associated with it, it would need memory of at least around a petabyte of memory, although synpase memory change speeds are probably not faster than tape, and I know of plenty of installations with a petabyte on tape.

    But here is the kicker: Will those 100 teraflops be flops that can use thousands of inputs? Probably not. So I'd argue that to truly be as powerful as the human brain, you would need 100 petaflops of 1-2 input flops, with at least a petabyte tape system.

      Neuron firings per second: max 2 Khz
      Cortical neurons, which do most of the complex processing, only fire at about 1-5 Hz on average. Some neurons can fire in the kHz range, but not for very long.
      The total processing speed of ASCII Purple sounds about right for number of neurons in brain times the maximum number of pulses per second per neuron.
      It's a lot harder than that, which is what makes these kinds of estimations so silly. For one thing, 1 pulse does not equal 1 bit in a brain as it does in a transistor. A single firing of a neuron can transmit up to 3.5 bits. This is because the firing time is important to the information content and the activity of neighboring neurons is also important. A group of neurons firing all at once transmits much more information than those same neurons firing individually at random times (in most cases -- there are exceptions to this).
      Given there are 10E14 synapses, each one with at least a byte of synpatic weight associated with it, it would need memory of at least around a petabyte of memory
      You also need to keep track of the state of the neuron (membrane potential, neurotransmitter concentrations, etc). The state of the neuron and the recent activity of a synapse and its neighboring synapses influence how much the "weight" matters. Certain patterns of input count for more than others.

      Most of the calculations of brain processing power that you read about are made by people who either don't understand the problem or haven't thought about it enough. Our knowledge of how the brain processes and stores information is extremely primitive at this point, so any estimation of the processing power is not much more than a wild guess. As with other sciences, every answer we find raises more questions. The more we study the problem, the harder it becomes. One of the most difficult things to deal with is that the software is the hardware. To make matters worse, the hardware can (and does) change. It's a lot like a computer that builds and programs itself.

    Sir Roger Penrose, the brilliant methematical physicist, and Stuart Hammeroff, a medical researcher at the University of Arizona, have for years postulated that the human brain is a quantum computing substrate. Their hypothesis is that the cellular skeleton (cytoskeleton) of neurons, which is made up of so-called microtubules, functions as some type of quantum waveguide system, allowing for the production of large-scale coherent states of quantum superposition within the human nervous system. A nanotech quatum supercomputing neural net of amazing power might be between our ears! If this were to turn out to be true, one individual neuron might be more "powerful" than this whole computer!!! Perhaps this is unlikely, but given how little we know about the operation of large-scale logic in the brain, it cannot be ruled out. Penrose claims that this state of quantum superposition explains the sensations and operation of consciousness (a "soul" of sorts) as well. Read his book Shadows of the Mind for more info. There's lots of stuff about quantum consciousness on Hammeroff's page, too. Trippy stuff indeed.
