A new framework called PhysSAE has been developed for mechanistic interpretability of Physics-Informed Neural Networks (PINNs). This framework uses overcomplete sparse autoencoders to analyze the internal representations of PINNs, revealing how they encode physical features. The research demonstrates that PhysSAE can identify these features and causally intervene on them, showing that the discovered representations are sparse, physically structured, and can be interrogated post-hoc.
