Implementation and (Inverse Modified) Error Analysis for implicitly-templated ODE-nets

no code implementations31 Mar 2023 Aiqing Zhu, Tom Bertalan, Beibei Zhu, Yifa Tang, Ioannis G. Kevrekidis

We thus formulate an adaptive algorithm which monitors the level of error and adapts the number of (unrolled) implicit solution iterations during the training process, so that the error of the unrolled approximation is less than the current learning loss.

VPNets: Volume-preserving neural networks for learning source-free dynamics

1 code implementation29 Apr 2022 Aiqing Zhu, Beibei Zhu, Jiawei Zhang, Yifa Tang, Jian Liu

We propose volume-preserving networks (VPNets) for learning unknown source-free dynamical systems using trajectory data.
