Anomaly Detection via Graphical Lasso
Haitao Liu, Randy C. Paffenroth, Jian Zou +1
Anomalies and outliers are common in real-world data, and they can arise from many sources, such as sensor faults. Accordingly, anomaly detection is important both for analyzing th…
Network Topology Mapping from Partial Virtual Coordinates and Graph Geodesics
Anura P. Jayasumana, Randy Paffenroth, Gunjan Mahindre +2
For many important network types (e.g., sensor networks in complex harsh environments and social networks) physical coordinate systems (e.g., Cartesian), and physical distances (e.…
Robust PCA for Anomaly Detection in Cyber Networks
Randy Paffenroth, Kathleen Kay, Les Servi
This paper uses network packet capture data to demonstrate how Robust Principal Component Analysis (RPCA) can be used in a new way to detect anomalies which serve as cyber-network…
