GRAPHITE platform transforms heterophilic graphs to boost homophily, improving GNN performance for data scientists and AI developers.
Research Paper
Core Innovation
This paper introduces GRAPHITE, a framework that explicitly transforms graphs to increase homophily by adding feature nodes. Unlike prior work focusing on GNN architecture, GRAPHITE targets the root cause of heterophily, enabling more effective message passing between similar nodes. This leads to better performance on heterophilic graphs with minimal graph size increase.

Research Paper Overview
Graph Homophily Booster: Rethinking the Role of Discrete Features on Heterophilic Graphs
Summary
Graph neural networks (GNNs) struggle with heterophilic graphs where connected nodes have dissimilar features or labels. Existing methods focus on architecture but often underperform compared to simple MLPs on challenging datasets. This paper proposes GRAPHITE, a novel framework that directly increases graph homophily by transforming the graph through feature nodes, enabling homophilic message passing among similar nodes. The approach significantly improves homophily with minimal graph size increase and outperforms state-of-the-art methods on heterophilic graphs while maintaining competitive accuracy on homophilic graphs.
