Abstract
A method of and system for classifying a pattern wherein there is provided a node, the negative of a predetermined threshold signal is applied to the node, a plurality of digital signals in parallel, is provided the digital signals are converted to analog signals, the analog signals are applied to the node to provide a summation of the analog signals and the threshold signal on the node and a predetermined output is provided if the signal at the node is above a predetermined value. This provides the transfer of a weighted pattern to the threshold without addressing each threshold element individually.
Claims16
A method of classifying a pattern comprising the steps of:
- (a) providing a node;
- (b) applying the negative of a predetermined threshold signal to said node;
- (c) providing a plurality of digital signals in parallel;
- (d) converting said digital signals to analog signals;
- (e) applying said analog signals to said node to provide a summation of said signals and said threshold signal on said node;
- and
- (f) providing a predetermined output if the signal at said node is above a predetermined value.
A system for classifying a pattern comprising:
- (a) a node;
- (b) circuitry for applying the negative of a predetermined threshold signal to said node;
- (c) circuitry for providing a plurality of digital signals in parallel;
- (d) circuitry for converting said digital signals to analog signals;
- (e) circuitry for applying said analog signals to said node to provide a summation of said signals and said threshold signal on said node;
- and
- (f) circuitry for providing a predetermined output if the signal at said node is above a predetermined value.
