GPR‑GNN: Adaptive Universal Generalized PageRank Graph Neural Network for Over‑Smoothing and Generalization

This article reviews the Adaptive Universal Generalized PageRank Graph Neural Network (GPR‑GNN), explaining the logical framework and two fundamental defects of traditional GNNs—lack of universality and over‑smoothing—then presents the GPR‑GNN mechanism, theoretical analysis, extensive experiments, and future research directions.
