Topological Neural Tangent Kernel

Sanjukta Krishnagopal / May 5, 2026

arXiv:2605.01110v1 Announce Type: new
Abstract: Graph neural tangent kernels give a principled infinite-width theory for graph neural networks, but inherit a basic limitation of graph models: they see only pairwise structure. Many relational systems c…
