WebSimilarly 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 messages to average as both keys and values (note that this also includes the message to itself). WebSep 19, 2024 · The output layer consists of one four-dimensional graph attention layer. The first and third layers of the intermediate layer are multi-head attention layers. The second layer is a self-attention layer. A dropout layer with a dropout rate of 0.5 is added between each pair of adjacent layers. The dropout layers are added to prevent overfitting.
