Fully-connected Graph Transformer [14] was first introduced together with rudimentary utilisation of eigenvectors of the graph Laplacian as the node positional encoding (PE), to provide the otherwise graph-unaware Transformer a sense of nodes’ location in the input graph. Building on top of this work, SAN [36] implemented an invariantYou could pass a pointer to an array containing all the nodes. You could pass just the one starting node and work from there, if it's a fully connected graph. And finally, you could write a graph class with whatever data structures you need inside it, and pass a reference to an instance of that class.The fully-connected graph explores the interactions among parts of different individuals, providing part-level interaction context information.
