Schreier-Coset Graph Rewiring

Aryan Mishra, Randy Martinez, Lizhen Lin

The paper proposes Schreier-Coset Graph Rewiring, a group‑theoretic method that augments a graph with a Schreier‑Coset graph to reduce over‑squashing in graph neural networks while…

A Deep Generative Approach to Stratified Learning

Randy Martinez, Rong Tang, Lizhen Lin

While the manifold hypothesis is widely adopted in modern machine learning, complex data is often better modeled as stratified spaces -- unions of manifolds (strata) of varying dim…
