WebJan 8, 2024 · Hamilton et al. proposed graph sample and aggregate (GraphSAGE), a representation learning method that samples and aggregates vertex features from local neighbor nodes of a vertex. GraphSAGE defines the AGGREGATE function and CONCAT function. The AGGREGATE function aggregates information from neighbor nodes, while … WebDefining additional weight matrices to account for heterogeneity¶. To support heterogeneity of nodes and edges we propose to extend the GraphSAGE model by having separate neighbourhood weight matrices (W neigh ’s) for every unique ordered tuple of (N1, E, N2) where N1, N2 are node types, and E is an edge type. In addition the heterogeneous …
