Attention Graphons: A Graph Limit Perspective on Graph Transformers
Caio F. Deberaldini Netto, Moshe Eliasof, Luana Ruiz
Graph Transformers produce, for each attention head, a dense matrix of learned pairwise interactions. We ask a fundamental question: do these attention-induced graphs c…

Graph Semi-Supervised Learning for Point Classification on Data Manifolds
Caio F. Deberaldini Netto, Zhiyang Wang, Luana Ruiz
We propose a graph semi-supervised learning framework for classification tasks on data manifolds. Motivated by the manifold hypothesis, we model data as points sampled from a low-d…
