Graph Sampling for Scalable and Expressive Graph Neural Networks on Homophilic Graphs

A new algorithm for graph sampling has been proposed to enhance the performance of Graph Neural Networks (GNNs) on large networks. This method addresses the common issue of random subsampling, which often results in disconnected subgraphs and limits the model's expressivity. By leveraging feature homophily, the algorithm aims to maintain the structural integrity of graphs while improving scalability. This advancement is significant as it could lead to more effective applications of GNNs in various fields, making them more accessible for larger datasets.
