Abstract:
A method of rejecting out-of-class inputs for pattern classification comprising the steps of:providing a list of patterns including at least one in-context pattern; providing a rank tolerance; obtaining a pattern to be classified; generating a classifier score for each pattern in the list of patterns; ranking the classifier scores in decreasing order; determining the highest ranking score for an in-context pattern; and when the highest ranking score for the in-context pattern is one selecting the in-context pattern, when the highest ranking score for the in-context pattern is not one comparing the highest ranking score to the rank tolerance, when the highest ranking score for the in-context pattern is less than the rank tolerance selecting the in-context pattern, and when the highest ranking score for the in-context pattern is greater than the rank tolerance rejecting the in-context pattern.
