public class EvaluatedDescriptionPosNeg
extends EvaluatedDescription<ScorePosNeg>

This represents a class description, which has been evaluated by the learning algorithm, i.e. it has been checked which examples it covers. It can be used as return value for learning algorithms to make it easier for applications to assess how good an offered class description is and how it classifies particular examples.
