An extensive empirical study of state-of-the-art DGAD models is conducted, revealing that detection difficulty increases consistently with anomaly complexity, from simple localized irregularities to coordinated and temporally persistent structures.

Dynamic graph anomaly detection (DGAD) is critical for a wide range of applications where abnormal events are rare, evolving, and tightly coupled with temporal context. Despite rapid progress in modeling dynamic graphs, the evaluation of DGAD methods remains fragmented, leaving the strengths, limitations, and trade-off...
