arXiv:2603.12916v3 Announce Type: replace Abstract: Multivariate time series anomalies often manifest as shifts in cross-channel dependencies rather than simple amplitude excursions. In autonomous driving, for instance, a steering command might be internally consistent but decouple from the resulting lateral acceleration. Residual-based detectors can miss such anomalies when flexible sequence models still reconstruct signals plausibly despite altered coordination. We introduce AxonAD, an unsupervised detector that treats multi-head attention query evolution as a short horizon predictable proce
The proliferation of complex multivariate time series data from interconnected systems, like autonomous vehicles, necessitates advanced anomaly detection techniques that go beyond simple amplitude deviations.
This development addresses a critical gap in current anomaly detection, improving the reliability and safety of autonomous AI systems by identifying subtle behavioral shifts indicative of issues.
The ability to detect anomalies based on shifts in cross-channel dependencies, rather than just amplitude excursions, enhances the robustness and explainability of AI-driven monitoring systems.
