In parallel, random geometric graphs (RGGs) provide a well-defined probabilistic model that captures the interplay between geometry and connectivity in complex networks.<br><br>In this talk, I will discuss several efforts I have undertaken to bridge these two perspectives by studying GNNs through the lens of RGGs. In the first part, I will focus on the classic graph matching problem and show that, by leveraging a specific GNN, perfect recovery can be achieved even in high-noise regimes. In the second part, I will briefly highlight recent work demonstrating the provable benefits of graph attention networks (GATs) for a node regression task. This talk is based on joint work with Morgane Austern, Kenny Gu, and Somak Laha.<br><br></div><div><br></div><div>Bio:</div><div>Suqi Liu is an Assistant Professor in the Department of Statistics at the University of California, Riverside. He received his Ph.D. in Operations Research and Financial Engineering from Princeton University.
