NAMColloquium Learning-informed parameter identification in nonlinear time-dependent PDEs |  |
Speaker:Frau Dr. Tram Thi Ngoc Nguyen, Universität Graz
Organizer:Institut für Numerische und Angewandte Mathematik
Details:
We investigate the problem of learning an unknown nonlinearity in parameter-dependent PDEs. The nonlinearity is represented via a neural network of an unknown state. The learning-informed PDE model has three unknowns: physical parameter, state and nonlinearity. We propose an all-at-once approach to the minimization problem.
