Spectral Gap-Driven Coarsening for Dynamic Graph Neural Networks

Experimental results demonstrate that the coarsening technique significantly accelerates dynamic GNN training and inference without compromising predictive performance, offering a practical path toward scalable dynamic graph learning.

Learning Robust Hypergraph Embeddings for Distribution-Free Uncertainty Quantification

Contrastive Conformal HGNN (CCF-HGNN) is proposed that accounts for uncertainty in hypergraph-based models by explicitly regularizing on the hypergraph structure for guaranteed and robust uncertainty estimates.

Learning Robust Hypergraph Embeddings for Distribution-Free Uncertainty Quantification

Hypergraph representation learning has gained immense popularity over the last few years due to its applications in real-world domains like social network analysis, recommendation systems, biological network modeling, and knowledge graphs. However, hypergraph neural networks (HGNNs) lack rigorous uncertainty estimates,...
