New framework PhysSAE enhances interpretability of physics-informed neural networks

By PulseAugur Editorial · [1 sources] ·

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.

    PhysSAE: Mechanistic Interpretability with Sparse Autoencoders

    arXiv:2609.07061v1 Announce Type: new Abstract: Physics-Informed Neural Networks (PINNs) embed PDE residuals into neural network training, but their internal representations remain opaque: it is unknown what physical features their hidden layers encode or whether those features h…
