When Does Frequency Decomposition Benefit Physics-Informed Neural Networks? A Preliminary Ablation Study
A new arXiv preprint (2608.24940v1) introduces a dual-branch, spectrally-gated architecture (DBSG-PINN) for Physics-Informed Neural Networks, finding that frequency decomposition cuts relative L2 erro…
