Unsupervised Contextual Anomaly Detection for Database Systems
Summary: Unsupervised anomaly detection in database access via semantic-context comparison. Trans-DAS learns operation semantics with attention and bidirectional contexts; UCAD combines a preprocessing stage and a semantic-based detector to identify stealthy anomalies.
