Learning Discriminative and Generalizable Anomaly Detector for Dynamic Graph with Limited Supervision 事件

Learning Discriminative and Generalizable Anomaly Detector for Dynamic Graph with Limited Supervision arXiv:2602.20019v2 Announce Type: replace-cross Abstract: Dynamic graph anomaly detection is critical for many real-world applications but remains challenging due to the scarcity of labeled anomalies. Existing methods are either unsupervised or semi-supervised: unsupervised methods avoid the need for labeled anomalies but often produce ambiguous boundary, whereas semi-supervised methods can ove
