MemAudit: Post-hoc Auditing of Poisoned Agent Memory via Causal Attribution and Structural Anomaly Detection
Large language model agents increasingly rely on persistent memory to store past interactions, retrieve relevant demonstrations, and improve long-horizon task execution. However, t…
CoReVAD: A Contextual Reasoning Framework for Training-Free Video Anomaly Detection
Existing Video Anomaly Detection (VAD) methods typically rely on task-specific training, leading to strong domain dependency and high training costs. Moreover, most existing method…
CALAD: Channel-Aware contrastive Learning for multivariate time series Anomaly Detection
Multivariate time series anomaly detection has become increasingly important in real-world applications, where labeled data are often scarce. Many existing approaches rely on unsup…
POST: Prior-Observation Adversarial Learning of Spatio-Temporal Associations for Multivariate Time Series Anomaly Detection
Existing Multivariate Time Series Anomaly Detection (MTSAD) frameworks increasingly rely on integrating Graph Neural Networks (GNNs) with sequence models to capture complex spatio-…
Email Anomaly Detection: Catching Sender Issues in Real Time
Email anomaly detection identifies sending problems — bounce spikes, ISP blocks, complaint surges — in real time, before reputation damage compounds.…
