Abstract
A pattern recognizing content addressable memory system and method therefor, according to the present invention, "translates" patterns into a point in N-dimensional space. In both the analog and digital embodiments of the invention, data representing "items" or "discrete pieces" of reference patterns are stored throughout a highly-interconnected network of processing units. Data representing items of a pattern to be analyzed are input into the system and compared to each of the stored patterns. The distance between the point in N-space representing an unknown pattern and the point representing a reference pattern is inversely proportional to the degree of similarity between the unknown pattern and the reference pattern.
