# Pseudo-Hamiltonian neural networks
This repository contains the package phlearn for modelling pseudo-Hamiltonian ODE and PDE systems with neural networks, and example scripts for training and simulation.
See [(Eidnes et al., 2023)](https://doi.org/10.1016/j.physd.2023.133673) for a description of PHNN for ODEs.
See [(Eidnes and Lye, 2024)](https://doi.org/10.1016/j.jcp.2023.112738) for a description of PHNN for PDEs.
[Documentation available here](https://pseudo-Hamiltonian-neural-networks.readthedocs.io/en/latest/)
## Installation
The phlearn package is available via PyPi:
```
pip install phlearn
```
Alternatively, to get the latest updates not yet available on PyPi, you can clone this repository and install directly:
```
git clone https://github.com/SINTEF/pseudo-Hamiltonian-neural-networks.git
cd pseudo-Hamiltonian-neural-networks
pip install -e phlearn
```
