Aligning Transformers with Weisfeiler-Leman
Luis Müller, Christopher Morris
Graph neural network architectures aligned with the -dimensional Weisfeiler--Leman (-WL) hierarchy offer theoretically well-understood expressive power. However, these archit…

Towards Principled Graph Transformers
Luis Müller, Daniel Kusuma, Blai Bonet +1
Graph learning architectures based on the k-dimensional Weisfeiler-Leman (k-WL) hierarchy offer a theoretically well-understood expressive power. However, such architectures often…
