ABSTRACT:
Methods and apparatus, including computer program products, implementing and using techniques for finding deviations in data. A set of candidate patterns is generated. A set of exception patterns that occur in the data less frequently than expected assuming statistical independence is selected from the set of candidate patterns. Data records that comply with at least one of the exception patterns are processed as exception candidates.
