Scale-Aware Learning of Chaotic Dynamics on Unstructured Meshes via Binned Spectral Losses
Article summary
Quick briefing — cleaned from the original RSS feed
arXiv:2607.19387v1 Announce Type: new Abstract: Surrogate modeling for high-dimensional nonlinear dynamical systems that exhibit chaos requires mechanisms that preserve not only pointwise accuracy but also the scale-dependent structure of physical fields. Bandwise spectral power losses, such as the binned spectral loss function, provide such supervision on structured grids, where Fourier modes define a standard frequency decomposition. On irregular meshes, however, no canonical Fourier basis…
