Inference of Time-Varying Graph Topologies via Gaussian Processes

ICASSP 2024accepted

In this paper, we explore the estimation of directed time-varying graph topologies, which represent evolving relationships among nodes in high-dimensional, interdependent data. We introduce a novel fully Bayesian method based on Gaussian processes, employing random walks to model the time-varying ed…

Estimation of Time-Varying Graph Topologies from Graph Signals

Yuhao Liu, Chen Cui, Marzieh Ajirak, Petar M. Djuric

ICASSP 2023accepted

In science and engineering, we often deal with signals that are acquired from time-varying systems represented by dynamic graphs. We observe these signals, and the interest is in finding the time-varying topology of the graphs. We propose two Bayesian methods for estimating these topologies without…
