WebDec 28, 2024 · Graph Transformers + Positional Features. While GNNs operate on usual (normally sparse) graphs, Graph Transformers (GTs) operate on the fully-connected graph where each node is connected to every other node in a graph. On one hand, this brings back the O(N²) complexity in the number of nodes N. On the other hand, GTs do … WebGraph Transformer. Graph neural networks (GNN) have gained increasing research interests as a mean to the challenging goal of robust and universal graph learning. Previous GNNs have assumed single pre-fixed graph structure and permitted only local context encoding. This paper proposes a novel Graph Transformer (GTR) architecture that …
