A new research paper explores the interpretability challenges of using foundation models for scientific simulations, specifically focusing on a continuum dynamics model called Walrus by Polymathic. Researchers used a sparse autoencoder to analyze over 20,000 features, guided by physical principles like enstrophy, to understand how the model represents physical phenomena. The study found that while some features recurred in similar roles across different simulations, the model's internal representations did not cleanly map to standard physical decompositions, and it exhibited systematic output discrepancies compared to traditional numerical simulations.
