1. A system that comprises:

  • transducer means to sense an input thereto and operable to provide a first output signal representative of said input;

    self-organizing circuit means connected to receive said first output signal and operable to effect analysis of constituent elements of said input and provide a further output signal related to said input, each self-organizing circuit of said self-organizing circuit means including a plurality of sub-circuits or levels which are connected to receive messages from some other sub-circuit or level and are operable to deliver messages to some other sub-circuit or level, there being voting in that each sub-circuit or level weights relative amounts of negative and positive influence thereto and votes whether or not to pass along information to the further sub-circuits or levels; and

    error correcting means acting on each subcircuit or level of the self-organizing circuit means which serves to correct errors in said further output signal by modifying the strength of the connections between said sub-circuits or levels occasioned by inaccurate analysis of the input by the self-organizing circuit means, and for effecting analysis of a first pattern of constituent elements and at a later time to apply said error correcting means to effect analysis of a second pattern of constituent elements without modifying the strength of at least a portion of said connections made during said first application of error correcting means.
