LPCVAE: A CONDITIONAL VAE WITH LONG-TERM DEPENDENCY AND PROBABILISTIC TIME-FREQUENCY FUSION FOR TIME SERIES ANOMALY DETECTION

Time series anomaly detection(TSAD) is a critical task in signal processing field, ensuring the reliability of complex systems. Reconstruction-based methods dominate in TSAD. Among these methods, VAE-based methods have achieved promising results. Existing VAE-based methods suffer from the limitation…
