Efficient Training of Physics-enhanced Neural ODEs via Direct Collocation and Nonlinear Programming
Linus Langenkamp, Philip Hannebohm, Bernhard Bachmann
We propose a novel approach for training Physics-enhanced Neural ODEs (PeN-ODEs) by expressing the training process as a dynamic optimization problem. The full model, including neu…
