Splet10. sep. 2024 · What if we want to extend this idea to PDE (Non-Linear)? There is an excellent paper by George Em Karniadakis – (Physics informed Deep Learning, Solutions of Nonlinear Partial Differential Equations). Thanks for reading this article! I hope it helped you in realizing how powerful the Neural Network function approximator is for real-life use. SpletThe cost of PINNs training remains a major challenge of Physics-informed Machine Learning (PiML) – and, in fact, machine learning (ML) in general. This paper is meant to move towards addressing the latter through the study of PINNs on new tasks, for which parameterized PDEs provides a good testbed application as tasks can be easily defined …
