Abstract

Method and apparatus rejecting out-of-class inputs for pattern classification including a list of patterns with at least one in-context pattern and a rank tolerance. An input pattern is used to generate a classifier score for each pattern in the list and the classifier scores are ranked in decreasing order. The highest ranking score for an in-context pattern is determined and if the highest ranking score is 1 the in-context pattern is selected. If the highest ranking score is not 1 it is compared to the rank tolerance. When the highest ranking score is less than the rank tolerance the in-context pattern is selected and when the highest ranking score is greater than the rank tolerance the in-context pattern is rejected. Cohorts of the highest ranking pattern are removed from the list prior to the comparison.
