Towards Foundation Models for Zero-Shot Time Series Anomaly Detection: Leveraging Synthetic Data and Relative Context Discrepancy

Researchers introduce TimeRCD, a foundation model for time series anomaly detection that uses a novel Relative Context Discrepancy approach instead of traditional reconstruction methods. The model achieves superior zero-shot performance by detecting discrepancies between adjacent time windows, addressing fundamental limitations in existing anomaly detection systems that produce high false positive and negative rates.
