Supra-Laplacian Encoding for Transformer on Dynamic Graphs

no code implementations26 Sep 2024 Yannis Karmim, Marc Lafon, Raphaël Fournier S'Niehotta, Nicolas Thome

Fully connected Graph Transformers (GT) have rapidly become prominent in the static graph community as an alternative to Message-Passing models, which suffer from a lack of expressivity, oversquashing, and under-reaching.

ITEM: Improving Training and Evaluation of Message-Passing based GNNs for top-k recommendation

no code implementations3 Jul 2024 Yannis Karmim, Elias Ramzi, Raphaël Fournier-S'niehotta, Nicolas Thome

Moreover, we extend the evaluation of GNN models for top-k recommendation tasks with an inductive user-centric protocol, providing a more accurate reflection of real-world applications.
