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 ... WebApr 15, 2024 · 3.1 Overview.
