WebJan 13, 2024 · 5 Conclusion. We propose an anomaly detection method for multiple time series, called GNF. The GNF uses Bayesian networks to model the structural relationships between multiple time series. We design an encoder to summarize the conditional information required for the normalizing flow to density estimation.
