Abstract
En 中文
In the era of rapidly expanding graph-based applications, efficiently managing large-scale graphs has become a critical challenge. This paper introduces an innovative graph reduction technique, Node-Centric Pruning (NCP), designed to simplify complex graphs while preserving their essential structural properties, thereby enhancing the scalability and maintaining performance of downstream Graph Neural Networks (GNNs). Our proposed approach strategically prunes less significant nodes and refines the graph structure, ensuring that critical topological properties are maintained. By carefully evaluating node significance based on advanced connectivity metrics, our method preserves the topology and ensures high performance in downstream machine learning tasks. Extensive experimentation demonstrates that our proposed method not only maintains the integrity and functionality of the original graph but also significantly improves the computational efficiency and preserves the classification performance of GNNs. These enhancements in computational efficiency and resource management make our technique particularly valuable for deploying GNNs in real-world applications, where handling large, complex datasets effectively is crucial. This advancement represents a significant step toward making GNNs more practical and effective for a wide range of applications in both industry and academia.
