Null hypothesis test for anomaly detection
Physics Letters B, 2023 We extend the use of Classification Without Labels for anomaly detection with a hypothesis test designed to exclude the background-only hypothesis. By testing for statistical independence of the two discriminating dataset regions, we are able to exclude ...
