Stgat-Mad : Spatial-Temporal Graph Attention Network For Multivariate Time Series Anomaly Detection

Anomaly detection in multivariate time series data is challenging due to complex temporal and feature correlations. This paper proposes a novel unsupervised multi-scale stacked spatial-temporal graph attention network for multivariate time series anomaly detection (STGAT-MAD). The core of our framew…
