Double

Remarks

The area under the precision/recall curve is a single number summary of the information in the precision/recall curve. It is increasingly used in the machine learning community, particularly for imbalanced datasets where one class is observed more frequently than the other. On these datasets, AreaUnderPrecisionRecallCurve can highlight performance differences that are lost with AreaUnderRocCurve.
