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 …
