NeighborDiv: Training-free Zero-shot Generalist Graph Anomaly Detection via Neighbor Diversity
Two new research papers introduce novel approaches to generalist anomaly detection. NeighborDiv focuses on graph data, proposing a training-free method that analyzes the diversity within a node's neighbors rather than node-to-neighbor consistency, achieving state-of-the-art results. Res$^2$CLIP tackles few-shot generalist anomaly detection by aligning multimodal representations within a residual space, aiming to improve generalization across novel categories without retraining.
