ADAPTIVE OUTLIER DETECTION AND CORRECTION

An embodiment detects, by an outlier detector, a first potential outlier in a data structure. The embodiment determines, by the outlier detector, whether the first potential outlier is a first outlier based on a first threshold. The embodiment applies, by an outlier corrector, responsive to determining the first potential outlier is a first outlier, a data quality rule to the first outlier. The embodiment detects, by the outlier detector, a second potential outlier in the data structure. The embodiment decreases, by the outlier detector, the first threshold to a second threshold. The embodiment determines, by the outlier detector, whether the second potential outlier is a second outlier based on the second threshold. The embodiment applies, by the outlier corrector, responsive to determining the second potential outlier is a second outlier, the data quality rule to the second outlier.
