Stochastic Pattern Recognition Dramatically Outperforms Conventional Techniques - Techn... - 2 views

stochastic probabilistic computing pattern_recognition robotics navigation

shared by Luís F. Simões on 23 Feb 12 - No Cached
  • A stochastic computer, designed to help an autonomous vehicle navigate, outperforms a conventional computer by three orders of magnitude, say computer scientists
  • These guys have applied stochastic computing to the process of pattern recognition. The problem here is to compare an input signal with a reference signal to determine whether they match.   In the real world, of course, input signals are always noisy so a system that can cope with noise has an obvious advantage.  Canals and co use their technique to help an autonomous vehicle navigate its way through a simple environment for which it has an internal map. For this task, it has to measure the distance to the walls around it and work out where it is on the map. It then computes a trajectory taking it to its destination.
  • Although the idea of stochastic computing has been around for half a century, attempts to exploit have only just begun. Clearly there's much work to be done. And since one line of thought is that the brain might be a stochastic computer, at least in part, there could be exciting times ahead.

    In a jaw-dropping feat of engineering, electronics turn a person's thoughts into commands for a drone. Using a brain-computer interface technology pioneered by University of Minnesota biomedical engineering professor Bin He, several young people have learned to use their thoughts to steer a flying robot around a gym, making it turn, rise, dip, and even sail through a ring.

Neural Networks Designed to 'See' are Quite Good at 'Hearing' As Well - 2 views

shared by pacome delva on 08 Jun 10 - Cached
  • Neural networks -- collections of artificial neurons or nodes set up to behave like the neurons in the brain -- can be trained to carry out a variety of tasks, often having something to do with pattern or sequence recognition. As such, they have shown great promise in image recognition systems. Now, research coming out of the University of Hong Kong has shown that neural networks can hear as well as see. A neural network there has learned the features of sound, classifying songs into specific genres with 87 percent accuracy.
  • Similar networks based on auditory cortexes have been rewired for vision, so it would appear these kinds of neural networks are quite flexible in their functions. As such, it seems they could potentially be applied to all sorts of perceptual tasks in artificial intelligence systems, the possibilities of which have only begun to be explored.

    Great, just great!! The conclusion seems to be "Thus IBMT could provide a means for improving self-regulation and perhaps reducing or preventing various mental disorders." Why all this neuro-bio-nonsense?? Wasn't this conclusion known before just using good old classic psychology and similar? Again one of these studies that thinks to provide new evidence just because they made a boring brain scan...

INF reversible logic computing chip electronics quantum cellular_automata

shared by Luís F. Simões on 25 Jan 11 - No Cached
  • Reversible logic could cut the energy wasted by computers to zero. But significant challenges lie ahead.
  • By some estimates the difference between the amount of energy required to carry out a computation and the amount that today's computers actually use, is some eight orders of magnitude. Clearly, there is room for improvement.
  • There are one or two caveats, of course. The first is that nobody has succeeded in building a properly reversible logic gate so this work is entirely theoretical. But there are a number of computing schemes that have the potential to work like this. Thapliyal and Ranganathan point in particular to the emerging technology of quantum cellular automata and show how their approach might be applied.
