WebIntroducing attention to GCN. The key difference between GAT and GCN is how the information from the one-hop neighborhood is aggregated. For GCN, a graph convolution operation produces the normalized sum of the node features of neighbors. h ( l + 1) i = σ( ∑ j ∈ N ( i) 1 cijW ( l) h ( l) j) where N(i) is the set of its one-hop neighbors ... WebOct 6, 2024 · Hu et al.
