CTGuard: A Calibrated Cross-System Log Anomaly Detection System for Resilient Cloud and HPC Operations

While system logs can be used to alert cloud and high-performance computing operators to incidents, real-world log anomaly detectors are often unreliable when log streams vary across platforms, when anomalies are highly imbalanced, or when alert thresholds are chosen without proper operational risk control. In this wor...
