Inductive Representation Learning on Large Graphs

WebApr 6, 2024 · The second one directly outputs the node embeddings. As we're dealing with a multi-class classification task, we'll use the cross-entropy loss as our loss function. I also added an L2 regularization of 0.0005 for good measure. To see the benefits of GraphSAGE, let's compare it with a GCN and a GAT without any sampling. WebGraphSAGE is a representation learning technique for dynamic graphs. It can predict the embedding of a new node, without needing a re-training procedure. To do this, GraphSAGE uses inductive learning.
