1. A method of recognizing patterns, said method comprising the steps of:

  • storing a plurality of recognition patterns in at least one memory, and storing in said memory respective parameters defining respective radii of attraction for the recognition patterns;

    receiving a recall pattern;

    comparing certain bits of said recall pattern to certain bits of said plurality of recognition patterns and rejecting certain of the recognition patterns based on the bit-wise comparison;

    correlating said recall pattern with at least said plurality of recognition patterns in said memory which are not rejected to determine respective measures of closeness for the recognition patterns which are not rejected, wherein said correlating includes adjusting the respective correlations by the respective parameters to determine the respective measure of closeness for the recognition patterns which are not rejected; and

    inspecting said measures of closeness to identify at least one closest one of the recognition patterns which are not rejected.
