WebSep 13, 2024 · GAT takes as input a graph (namely an edge tensor and a node feature tensor) and outputs [updated] node states. The node states are, for each target node, … WebThis concept can be similarly applied to graphs, one of such is the Graph Attention Network (called GAT, proposed by Velickovic et al., 2024). Similarly to the GCN, the graph attention layer creates a message for each node using a linear layer/weight matrix. For the attention part, it uses the message from the node itself as a query, and the ...
