Abstract Multivariate time series present significant methodological challenges for anomaly detection, primarily due to the intricate nature of their temporal dependencies and the dynamic interplay among variables. These complexities render traditional methods inadequate for precise and reliable anomaly detection. This paper confronts these challenges by introducing an innovative, unsupervised framework that concurrently integrates data encoding, preservation of temporal structure, and residual analysis. By modeling temporal dependencies through sinusoidal exponential decay functions, our approach identifies deviations from this model in the latent space as anomalies. We validate the effectiveness of our framework through extensive experiments on real-world datasets, benchmarking it against state-of-the-art approaches.
