Historical Sketch
  • Pre-1940 von Hemholtz, Mach, Pavlov, etc.
  • General theories of learning, vision,
    conditioning
  • No specific mathematical models of neuron
    operation
  • 1940s Hebb, McCulloch and Pitts
  • Mechanism for learning in biological neurons
  • Neural-like networks can compute any arithmetic
    function
  • 1950s Rosenblatt, Widrow and Hoff
  • First practical networks and learning rules
  • 1960s Minsky and Papert
  • Demonstrated limitations of existing neural
    networks, new learning algorithms are not
    forthcoming, some research suspended
  • 1970s Amari, Anderson, Fukushima, Grossberg,
    Kohonen
  • Progress continues, although at a slower pace
  • 1980s Grossberg, Hopfield, Kohonen, Rumelhart,
    etc.
  • Important new developments cause a resurgence in
    the field

Biology Inspiration
Neurons respond slowly 10-3 s compared to
10-9 s for electrical circuits The brain uses
massively parallel computation 1011 neurons
in the brain 104 connections per neuron
  • Human nervous system is built of cells call
    neuron Each neuron can receive, process and
    transmit electrochemical signals Dendrites extend
    from the cell body to other neurons, and the
    connection point is called synapse Signals
    received among dendrites are transmitted to and
    summed in the cell body If the cumulative
    excitation exceed a threshold, the cell fires,
    which sends a signal down the axon to other
    neurons
