| Popis: | Online event detection in streaming time series is a critical task with applications across various domains. For example, the right-on-time event detection for control systems is a key for correctly addressing the issues related to the events. However, events may not be identified right after their occurrence. Depending on the monitoring solution, a time difference may exist between the event’s occurrence and detection. This problem raises research questions regarding the study of such a temporal gap. The paper introduces novel metrics (detection probability and detection lag) to address these questions. It explores the impact of configurable batches on detection performance. The experimental evaluation of diverse datasets reveals nuanced insights into the interplay between batch parameters, detection accuracy, and computational performance. |
