WebGraphSAGE GraphSAGE [Hamilton et al. , 2024 ] works by sampling and aggregating information from the neighborhood of each node. The sampling component involves randomly sampling n -hop neighbors whose embeddings are then aggregated to update the node's own embedding. It works in the unsu-pervised setting by sampling a positive … Webneighborhood. GraphSAGE [3] introduces a spatial aggregation of local node information by different aggregation ways. GAT [11] proposes an attention mechanism in the aggregation process by learning extra attention weights to the neighbors of each node. Limitaton of Graph Neural Network.
