GraphSAGE: Scaling up Graph Neural Networks - Maxime Labonne

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 ... WebFeb 3, 2024 · Furthermore, we suggest that inductive learning and attention mechanism is crucial for text classification using graph neural networks. So we adopt GraphSAGE (Hamilton et al., 2024) and graph attention networks (GAT) (Velickovic et al., 2024) for this classification task. reading epc
