Method and computer program product for identifying and incorporating new output classes in a pattern recognition system during system operation
First Claim
1. A method for identifying one or more new pattern classes and incorporating the classes into a pattern recognition classifier as output classes, comprising:
- rejecting a plurality of input patterns determined not to be associated with any of a set of at least one represented output class by a pattern recognition classifier;
grouping the rejected pattern samples into clusters according to the similarities between the pattern samples;
identifying clusters that represent new pattern classes via independent review; and
retraining the classifier to include the new pattern classes as output classes.

Abstract
The present invention recites a method and computer program product for identifying one or more new pattern classes and incorporating the classes into a pattern recognition classifier as output classes. A plurality of input patterns determined not to be associated with any of a set of at least one represented output class by a pattern recognition classifier are rejected. The rejected pattern samples are then grouped into clusters according to the similarities between the pattern samples. Clusters that represent new pattern classes are identified via independent review. The classifier is then retrained to include the new pattern classes as output classes.

7. A computer program product, operative in a data processing system, for identifying one or more new pattern classes and incorporating the pattern classes into a pattern recognition classifier as output classes, comprising:
-
a classification portion that rejects a plurality of input patterns determined not to be associated with any of a set of at least one represented output class;
a clustering portion that groups the rejected pattern samples into clusters according to the similarities between the pattern samples;
a class identification portion that identifies clusters that represent new pattern classes via an independent review; and
a training portion that retrains the classifier to include the new pattern classes as output classes. - View Dependent Claims (8, 9, 10, 11, 12)
