Researchers have developed StablePDENet, a novel physics-informed adversarial training method designed to enhance the stability of neural operators used for solving differential equations. This method addresses the critical challenge of maintaining stability under input perturbations by regularizing the residual sensitivity. StablePDENet formulates the operator learning task as a min-max optimization problem, incorporating a physics-based adversary and a normalized residual-sensitivity penalty. Evaluations show that StablePDENet outperforms existing methods like PI-DeepONet in accuracy under adversarial conditions while maintaining competitive performance on clean inputs, offering a practical approach to more stable and physically consistent neural PDE operators.
