Towards an Awareness of Time Series Anomaly Detection Models' Adversarial Vulnerability. (arXiv:2208.11264v1 [cs.LG])
cs.CR updates on arXiv.org arxiv.org
Time series anomaly detection is extensively studied in statistics,
economics, and computer science. Over the years, numerous methods have been
proposed for time series anomaly detection using deep learning-based methods.
Many of these methods demonstrate state-of-the-art performance on benchmark
datasets, giving the false impression that these systems are robust and
deployable in many practical and industrial real-world scenarios. In this
paper, we demonstrate that the performance of state-of-the-art anomaly
detection methods is degraded substantially by adding only small adversarial
perturbations …
