1. A method of comparing an input pattern with a memory pattern comprising the steps of:

  • loading a representation of said input pattern into cells in an input layer;

    loading a representation of said memory pattern into cells in a memory layer;

    loading an initial value into cells in an intermediate layers between said input layer and said memory layer;

    comparing values of cells in said intermediate layers with values stored in cells of adjacent layers including calculating a far differential —

    far span k distance connection from said cell in said intermediate layer to said cells in said intermediate layers;

    updating values stored in cells in said intermediate layers based on said step of comparing; and

    mapping cells in said memory layer to cells in said input layer.
