arXiv:2605.25662v1 Announce Type: new Abstract: Graph neural networks for node classification are typically trained by gradient descent over hundreds or thousands of epochs. Recent work has shown that, when properly tuned, classic GCN/SAGE/GAT architectures can match graph transformers on many node-classification benchmarks. We ask a complementary question: how much of this performance can be recovered by deterministic closed-form solvers, and what guarantees does this enable? We introduce a routed closed-form framework selected by adjusted homophily. For assortative graphs, we use SGC-style p
The paper addresses current challenges in Graph Neural Network (GNN) training efficiency and performance, catalyzed by the rapid advancements and widespread adoption of AI technologies, particularly in areas like node classification.
This research provides a foundational improvement in GNNs by exploring deterministic closed-form solutions, potentially offering more robust, faster, and explainable AI models compared to traditional gradient-descent methods.
The focus shifts towards achieving comparable or better performance in node classification with more efficient, transparent, and potentially less computationally intensive methods, enhancing the practical deployment of GNNs.
