ACR-PINN: Layer-wise Adaptation and Gradient Conflict Resolution for PINNs

Researchers propose ACR-PINN, a physics-informed neural network framework that pairs layer-wise dynamic adaptation of coordinate representations with a method for resolving conflicts among gradients coming from heterogeneous physical constraints. The work frames architecture and optimization as a joint design problem, aiming to improve training when competing constraints pull the model in different directions.
