Time-Varying Graph Learning for Data with Heavy-Tailed Distribution
December 2024 • Amirhossein Javaheri, Jiaxi Ying, Daniel P. Palomar, Farokh Marvasti
Graph models provide efficient tools to capture the underlying structure of data defined over networks. Many real-world network topologies are subject to change over time. Learning to model the dynamic interactions between entities in such networks is known as time-varying graph learning. Current methodology for learning such models often lacks robustness to outliers in the data and fails to handle heavy-tailed distributions, a common feature in many real-world datasets (e.g., financial data). This paper addresses…
