# Studying Lagrangian theories with machine learning: a toy model

@article{Anagnostopoulos2020StudyingLT, title={Studying Lagrangian theories with machine learning: a toy model}, author={Fotios Anagnostopoulos and Christos Valelis and Spyros Basilakos and Emmanuel N. Saridakis}, journal={arXiv: Computational Physics}, year={2020} }

The existence or not of pathologies in a Lagrangian theory is studied with the aid of Machine Learning algorithms. Using a toy model in the framework of classical mechanics, we make a proof of concept, that the construction of new physical theories using machine learning is possible. Specifically, we utilize a fully-connected, feed-forward neural network architecture, aiming to discriminate between "healthy" and "non-healthy" Lagrangians, without explicitly extracting the relevant equations of…
