Sheaf Graph Neural Networks via PAC-Bayes Spectral Optimization

Yoonhyuk Choi, Jiho Choi, Chong-Kwon Kim

Over-smoothing in Graph Neural Networks (GNNs) causes collapse in distinct node features, particularly on heterophilic graphs where adjacent nodes often have dissimilar labels. Alt…

Hierarchical Uncertainty-Aware Graph Neural Network

Yoonhyuk Choi, Jiho Choi, Taewook Ko +1

Recent research on graph neural networks (GNNs) has explored mechanisms for capturing local uncertainty and exploiting graph hierarchies to mitigate data sparsity and leverage stru…

Adaptive Branch Specialization in Spectral-Spatial Graph Neural Networks for Certified Robustness

Yoonhyuk Choi, Jiho Choi, Chong-Kwon Kim

Recent Graph Neural Networks (GNNs) combine spectral-spatial architectures for enhanced representation learning. However, limited attention has been paid to certified robustness, p…
