Let¡¯s now look at the detection performance. Results are shown in the bar chart. Spikes and dips achieved a true positive rate of 94% with zero false positives. Trends performed well at 100% TPR and only 0% FPR. Level shifts also reached 100% TPR, but with a higher 20% FPR, primarily because gradual trends were misclassified as level shifts. Overall, the algorithms show excellent sensitivity with acceptable specificity — level-shift tuning is the main improvement needed.
