Abstract: Detecting, analyzing and reasoning anomalies is important for many real-life application domains such as computer networking, fraud analysis, and software security. The main challenges include the overwhelming number of low-risk events and their multifaceted relationships, the diversity of anomalies by various data and anomaly types, and the difficulty to incorporate domain knowledge in the anomaly analysis process. In this talk, we introduce a suite of novel concepts called correlation graphs (CG). CG achieves computational scalability, domain generality, and user interactivity through synthesizing heterogeneous types of objects, their anomalies, and multifaceted relationships in a single graph. We propose relevant anomaly detection algorithms, elaborate visualization designs, and interaction models to allow users to fully unleash the visual analytics power over the correlation graph. Case studies in real-world applications are presented that demonstrate the effectiveness of CG in the data-driven detection, visualization, and reasoning process of anomalies.
