arXiv:2602.08638v2 Announce Type: replace Abstract: As a fundamental data mining task, unsupervised time series anomaly detection (TSAD) aims to build a model for identifying abnormal timestamps without assuming the availability of annotations. A key challenge in unsupervised TSAD is that many anomalies are too subtle to exhibit detectable deviation in any single view (e.g., time domain), and instead manifest as inconsistencies across multiple views like time, frequency, and a mixture of resolutions. However, most cross-view methods rely on feature or score fusion and do not enforce analysis-s
The proliferation of complex time-series data and the increasing demand for real-time insights are driving innovation in robust anomaly detection methods.
Advanced unsupervised time series anomaly detection can significantly enhance operational efficiency, predictive maintenance, and cybersecurity across various industries by identifying subtle, previously undetectable issues.
The ability to detect subtle anomalies across multiple data views, rather than relying on single-view analysis, improves the accuracy and reliability of automated monitoring systems.
