Method and computer program product for generating training data for a new class in a pattern recognition classifier
First Claim
1. A method of generating training data over a plurality of feature variables for a new output class in a pattern recognition classifier representing a plurality of existing classes with previously calculated statistical parameters, comprising:
- generating deviation measures for each feature variable for each of the plurality of existing classes from the calculated statistical parameters;
averaging the deviation measures for each feature variable across the plurality of existing classes;
extracting feature data from an ideal pattern, representing the new class, for each of the feature variables; and
approximating statistical parameters for each feature variable for the new class from the extracted feature data and the averaged deviation measures.

Abstract
A method and computer program product are disclosed for generating training data over a plurality of feature variables for a new output class in a pattern recognition classifier representing a plurality of existing classes with previously calculated statistical parameters. Deviation measures are generated for each feature variable for each of the plurality of existing classes from the calculated statistical parameters. The deviation measures for each feature variable are averaged across the plurality of existing classes. Feature data is extracted from an ideal pattern, representing the new class, for each of the feature variables. Statistical parameters are approximated for each feature variable for the new class from the extracted feature data and the averaged deviation measures.
