Researchers have developed a new diagnostic tool to assess how well neural emulators of partial differential equations internalize physical symmetries. This method measures the propagation of parameter updates between symmetry-related states by analyzing the overlap of loss gradients along group orbits. Applied to fluid flow emulators, the technique demonstrates that gradient coherence is key to learning symmetry transformations and identifies when training converges to a symmetry-compatible solution.
