Nothing to show Webb1 juli 2024 · In the PINN method, AD allows the implementation of any PDE and boundary condition constraints without numerically discretizing and solving the PDEs. Another benefit of enforcing PDE constraints via the penalty term Jf ( θ, γ) is that it allows using the corresponding weight ωf to account for the fidelity of the PDE model. hipro yaourt danone
