arXiv:2606.04420v1 Announce Type: new Abstract: Physics-informed neural networks (PINNs) approximate solutions of ODEs and PDEs by minimising a weighted combination of residual, boundary, initial, and data losses. Their performance is often dominated by the choice of loss weights: a poor weighting can drive training to a degenerate solution in which one physical constraint is satisfied while another is ignored. Existing methods select or adapt a single good set of weights. We take a different view: instead of tuning one weight vector, we explore the entire weight space during training. We intr
The continuous evolution of AI research pushes for more robust and efficient methods to solve complex scientific and engineering problems.
Improving the training stability and performance of Physics-informed neural networks can accelerate discovery and design in fields relying on partial differential equations.
The proposed method of exploring the entire weight space during PINN training offers a more robust and less sensitive approach to hyperparameter tuning, potentially leading to more reliable AI solutions for PDEs.
