GADACE: Graph Anomaly Detection Combining Attribute Contrast and Structure Reconstruction

ICASSP 2025accepted

Unsupervised graph anomaly detection aims to identify nodes that deviate from typical behaviors in graphs. Existing approaches can be briefly categorized into two main groups, namely, reconstruction-based approaches that detect anomalies through reconstruction errors, and contrastive learning-based…

Learning Diffusions under Uncertainty

AAAI 2024technical

To infer a diffusion network based on observations from historical diffusion processes, existing approaches assume that observation data contain exact occurrence time of each node infection, or at least the eventual infection statuses of nodes in each diffusion process. They determine potential infl…
