Graphsage attention

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. The number of GNN layers is limited due to the Laplacian WebHere we present GraphSAGE, a general, inductive framework that leverages node feature information (e.g., text attributes) to efficiently generate node embeddings. Instead of training individual embeddings for each node, we learn a function that generates embeddings by sampling and aggregating features from a node's local neighborhood. Our ...
