Quadra-Brain is proposed, a computational framework for modeling quadruplet higher-order interactions in fMRI-based brain disease diagnosis and suggests that quadruplet interactions provide a meaningful representation of collective brain coordination and offer complementary insights beyond conventional connectivity-bas...
An edge-centric brain transformer (EBT) framework is proposed that reformulates rs-fMRI analysis as functional connection representation learning and consistently outperforms representative graph neural networks, brain transformers, and conventional connectivity-based approaches.

This work investigates hypergraph oversmoothing from a dynamical-systems perspective and develops a reaction--diffusion framework for depth-resistant hypergraph learning, which introduces a reaction mechanism acting on the transverse component to compensate diffusion-induced dissipation and stabilize discriminative var...
A new descriptive homophily measure for general social hypergraphs where group interactions involve arbitrary number of individuals is proposed, and constraints of monotonic and majority homophily for two-class labels are established, providing a framework for analyzing homophily patterns.
