A new research paper introduces methods to distinguish between genuine task-level value and mere checkpoint dependence in Sheaf Graph Neural Networks (GNNs). The study proposes two estimands: checkpoint reliance, which examines maps of a fixed predictor, and protocol-relative replacement, which retrains models to remove map capacity. The findings suggest that learned maps in these networks can govern fitted computations without necessarily representing indispensable edge geometry, highlighting the need for rigorous evaluation beyond simple checkpoint analysis.
