Neural network model in pattern recognition using probabilistic contextual information
First Claim
1. A system for recognizing an unknown pattern, said unknown pattern including one or more symbols which are part of a pattern system which is devoid of inherent context, comprising:
- storing means for storing artificial contextual information associated with said unknown pattern and based upon other than information as to symbol features and the pattern system; and
recognizer means responsive to said known pattern and to said artificial contextual information, said recognizer means having a processing phase wherein said recognizer means processes at least one symbol of said unknown pattern and outputs as a recognition decision that said one symbol is one of a plurality of category names and wherein in reaching said recognition decision during said processing phase utilizes said artificial contextual information.

Abstract
A pattern recognition system for recognizing an unknown pattern comprised of symbols which are part of a pattern system which is devoid of inherent context such as numbers. Artificial contextual information based on other than symbol features and the pattern system and in the form of probability weighted expected interpretations are stored and used in the processing phase of recognition. In the system disclosed, the system comprises a neural network whose forward and feedback paths are controlled by the output cells of the network based, in part, on the contextual information.

17. A method of recognizing an unknown pattern, said unknown pattern including one or more symbols which are part of a pattern system which is devoid of inherent context, comprising:
-
storing artificial contextual information associated with said unknown pattern and based upon other than information as to symbol features and the pattern system; and recognizing said unknown pattern by processing at least one symbol of said unknown pattern and outputting as a recognition decision that said one symbol is one of a plurality of category names utilizing said artificial contextual information. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
