Sparse autoencoders used to probe physics-informed neural network internals

A new arXiv paper introduces PhysSAE, a method that applies sparse autoencoders to inspect what hidden layers in physics-informed neural networks actually represent. The authors aim to determine whether these networks learn localized, physically meaningful features tied to the PDE residuals they are trained on. The work falls within mechanistic interpretability research for scientific machine learning.
