Abstract:
A pattern recognition apparatus comprising:first pattern recognition means for classifying a plurality of inputted patterns to classification classes to which said patterns belong, evaluating reliability of the classification result and outputting the classification classes to which said pattern belong, as recognizable, for those of said patterns which provide the classification result having high reliability; first storage means for storing those of said patterns for which said classification results are evaluated as having low reliability by said first pattern recognition means and for which recognition is suspended; second storage means for storing those of said patterns for which said classification results are evaluated as having high reliability by said first pattern recognition means and said classification classes outputted by said first pattern recognition means; second pattern recognition means for inputting said patterns stored in said first storage means and outputting said classification classes to which said patterns belong by using said patterns and said classification classes stored in said second storage means as a training sample; and pattern recognition method construction means for constructing said second pattern recognition means by using said patterns and said classification classes stored in said second storage means as a training sample.
