Dynamic & norm-based weights to normalize imbalance in back-propagated gradients of physics-informed neural networks
Physics-Informed Neural Networks (PINNs) have been a promising machine learning model for evaluating various physical problems. Despite their success in solving many types of partial differential equations (PDEs), some problems have been found to be difficult to learn, implying that the baseline PIN...
