Abstract:
1. A method performed by a computer with a processor, comprising: providing a reference pattern corresponding to a pattern signal, and one or more competing patterns; dividing the reference pattern and the one or more competing patterns into pattern segments, the pattern segments of the competing patterns identified with corresponding pattern segments of the reference pattern; generating, with the processor, a set of training patterns by replacing one of the pattern segments in the reference pattern with a corresponding competing pattern segment from one of the competing patterns or from a pre-defined confusion pattern; for each of the one or more training patterns, applying, with the processor, a pattern recognition model to evaluate a relative degree of correspondence of the reference pattern with the pattern signal compared to a degree of correspondence of the training patterns with the pattern signal, wherein the pattern recognition model incorporates correspondence parameters to features of the reference pattern and the training patterns; and revising, with the processor, the correspondence parameters to increase the relative degree of correspondence of the reference pattern with the pattern signal compared to a degree of correspondence of the training patterns with the pattern signal.
