Summary: | With the proliferation of multivariate time series data in various fields, this paper proposes an anomaly detection method based on modelling the correlation of multivariate time series. The correlation between multivariate time series is quantified as a correlation matrix, which is combined with the original features as enhanced features for training anomaly detection models. Meanwhile, a deep learning network model is utilized to capture the temporal dependencies within sequences, thereby detecting anomalies caused by changes in inter-channel correlations. In experiments, our method produces higher precision, recall, and F1 scores compared to other state-of-the-art models, validating the effectiveness of the proposed method. |
