arXiv:2605.25001v1 Announce Type: new Abstract: While Physics-Informed Neural Networks (PINNs) are powerful for solving Partial Differential Equations (PDEs), their training is often paralyzed by gradient pathology. The gradients from the PDE residuals and boundary constraints oppose each other, trapping the model in local minima. Current solutions, such as adaptive weighting or hard constraints, either fail to fundamentally resolve this ill-conditioning or are limited to simple geometries. In this study, we systematically analyze the possible causes of this gradient pathology from the perspec
The continuous development and refinement of AI models necessitate addressing fundamental training inefficiencies, making this a timely advancement in AI research.
Improving the robustness and reliability of Physics-Informed Neural Networks directly impacts their applicability in complex scientific and engineering domains, accelerating discovery and design.
The ability to mitigate gradient pathology will make PINNs more stable and easier to train, expanding their use beyond highly specialized AI research labs.
