- Abstract:
-
Current graph neural network-based node classification methods rely on large amounts of labeled data and are limited by long-tailed label distributions. In low-resource settings, meta-learning-based few-shot learning is effective for graph representation. However, global graph learning introduces task-irrelevant noise, and current prototypical networks, which classify nodes by directly computing similarities between nodes and class prototypes, struggle to estimate accurate prototypes under few-shot conditions. To address these issues, we propose a task-aware subgraph-based few-shot node classification method (TAS-FNC). This method constructs high-connectivity subgraphs for each task through structural pruning and topological enhancement, enabling task-specific node representation learning and reducing noise. It then models the relationships between query nodes and class prototypes for classification. Experiments on four datasets against 11 baselines show that TAS-FNC effectively improves node classification accuracy in label-scarce scenarios.
