Neuromorphic NNW's
  • Neuromorphic refers to circuit design that closely emulates biological neural design.

    •  
  • The processing is mostly analog, although outputs can be digital.

    •  
  • The function may be as a sensor rather than as a pattern classifier.

    •  
  • Examples include:

    •  
    • Silicon Retina

      •  
    • Synaptics touchpad

      •  
    • Pulse Couple Neural Networks (PCNN):

      •  
      • Designed after the mammalian visual system, recently implemented in hardware.

        •  
      • PCNN's can perform image preprocessing, such as edge finding and segmentation.

        •  
      • Time series output invariant to scaling, rotation and translation.
