WebGraphSAGE aims to improve the efficiency of a GCN and reduce noise. It learns an aggregator rather than the representation of each node, which enables one to accurately distinguish a node from its neighborhood information. In addition, it can be trained in batches to improve the polymerization speed. ... A GAT computes the weight of each edge ... WebOct 12, 2024 · We can modify the edge_weight attribute before the forward pass of our graph neural network with the edge_norm attribute. edge_weight = data.edge_norm * data.edge_weight out = model (data.x, data.edge_index, edge_weight) [1] M. Fey. PyTorch Geometric. Graph Deep Learning library.
