Understanding Attributed Graphs
Attributed graphs combine topological structure with node features, enabling richer representations for complex systems. This paper addresses the unique challenges of detecting anomalies that arise from structural irregularities or attribute inconsistencies, or both.
Advanced Anomaly Detection
Anomaly detection identifies deviations from normal patterns. In attributed networks, anomalies can manifest as unusual links (structural deviations), inconsistent node properties (attribute deviations), or a combination (hybrid deviations). The goal is to learn a scoring function that highlights these anomalies.
Graph Representation Learning
This involves encoding graph data into low-dimensional continuous vectors (embeddings) that preserve both topological location and attribute semantics. Effective embeddings are crucial for downstream tasks like anomaly detection, as they capture the underlying relationships and patterns in the data.
The Power of Contrastive Learning
A powerful technique that refines embeddings by pulling similar nodes closer and pushing dissimilar nodes further apart in the embedding space. This enhances discriminative power, making the model more sensitive to structural and attribute-based abnormalities, which is key for robust anomaly detection.
