PINN Training using Biobjective Optimization: The Trade-off between Data Loss and Residual Loss

no code implementations3 Feb 2023 Fabian Heldmann, Sarah Berkhahn, Matthias Ehrhardt, Kathrin Klamroth

Physics informed neural networks (PINNs) have proven to be an efficient tool to represent problems for which measured data are available and for which the dynamics in the data are expected to follow some physical laws.

Event-based MILP models for ride-hailing applications

no code implementations2 Mar 2021 Daniela Gaul, Kathrin Klamroth, Michael Stiglmayr

We consider a static dial-a-ride problem (DARP) where a series of origin-destination requests have to be assigned to routes of a fleet of vehicles.

Efficient and Sparse Neural Networks by Pruning Weights in a Multiobjective Learning Approach

1 code implementation31 Aug 2020 Malena Reiners, Kathrin Klamroth, Michael Stiglmayr

We suggest a multiobjective perspective on the training of neural networks by treating its prediction accuracy and the network complexity as two individual objective functions in a biobjective optimization problem.
