MELODY: Robust Semi-Supervised Hybrid Model for Entity-Level Online Anomaly Detection with Multivariate Time Series

no code implementations18 Jan 2024 Jingchao Ni, Gauthier Guinet, Peihong Jiang, Laurent Callot, Andrey Kan

We begin by identifying the challenges unique to this anomaly detection problem, which is at entity-level (e. g., deployments), relative to the more typical problem of anomaly detection in multivariate time series (MTS).
