Frequency decomposition boosts PINN accuracy on complex PDEs

Researchers have investigated the effectiveness of frequency decomposition techniques for Physics-Informed Neural Networks (PINNs), which are designed to approximate solutions to partial differential equations (PDEs). Their study, using a novel dual-branch, spectrally-gated architecture (DBSG-PINN), found that frequency decomposition significantly improves accuracy on spectrally complex benchmarks, reducing errors by up to 59.2% on certain wave problems. However, the benefits were minimal for smoother PDEs, and in one case, a simpler variant performed better. The study suggests that the effectiveness of these techniques is highly dependent on the spectral richness of the target solution. AI

    When Does Frequency Decomposition Benefit Physics-Informed Neural Networks? A Preliminary Ablation Study

    arXiv:2608.24940v1 Announce Type: new Abstract: Partial differential equations (PDEs) often have high-frequency and multi-scale features that neural networks struggle to approximate. Physics-Informed Neural Networks (PINNs) build the governing equations directly into training, bu…
