Researchers have developed a new method called Cautious Conflict-Free Inverse Gradient (Cautious ConFIG) to improve the training of Physics-Informed Neural Networks (PINNs). PINNs are used to solve complex physics and engineering problems by integrating physical constraints into neural network loss functions. However, this can lead to conflicting gradients. While the existing Conflict-Free Inverse Gradient (ConFIG) method addresses these conflicts, its integration with optimizers like Adam can result in updates that are no longer conflict-free. Cautious ConFIG is a small extension that ensures the conflict-freeness is maintained before the weight update, showing consistent performance improvements on benchmarks like the 1D Viscous Burgers' equation and the 2D Kovasznay flow.
