Web23 hours ago · The PINN is a versatile, deep-learning-based modeling technique that allows for the solving of PDEs [ 3 ], the construction of surrogate models [ 4] and the solving of ill-posed problems [ 5 ]. With a PINN, a neural network is used as a general function approximator, and is trained to approximate the solution of a PDE.
