Two new research papers explore the generalization capabilities of physics-informed machine learning models. The first paper introduces a comprehensive benchmark to evaluate physics foundation models across various physical regimes and distribution shifts, revealing that current models act as conditional generalists rather than universal ones. The second paper develops a PAC-Bayesian framework to provide statistical generalization guarantees for physics-informed machine learning, linking physical regularity directly to improved generalization and proposing a new learning algorithm.
