TOF detects unique events only. Detection performance measured by ROC AUC as a function of the minimum Inter-Event Interval (IEI) between two inserted tent-map outlier segments. TOF was able to distinguish outliers from the background very well when IEIs were below 300 steps, and the two events can be considered one. However, the detection performance of TOF decreased for higher IEIs. In contrast, LOF’s peak performance was lower, but independent of the IEI.
