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 … WebE-minBatch GraphSAGE Attack Detection Model. As shown in Figure 4, the E-minBatch GraphSAGE attack detection model proposed in this paper first generates a network graph using network stream data, and then presamples the nodes once. After completing the presampling, the data is fed into the model for training.
