WebIn this example we use two GAT layers with 8-dimensional hidden node features for the first layer and the 7 class classification output for the second layer. attn_heads is the number of attention heads in all but the last GAT layer in the model. activations is a list of activations applied to each layer’s output. 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 ...
