Physics-Informed Neural Networks for Discovering Periodic Orbits in the Gravitational Three-Body Problem

Nikolaos Kollias, Nikolaos Matzakos

Locating periodic solutions of chaotic dynamical systems normally requires an initial guess close enough to the target orbit for numerical continuation or gradient-based search to…

Activation Saturation and Floquet Spectrum Collapse in Neural ODEs

Nikolaos M. Matzakos

We prove that activation saturation imposes a structural dynamical limitation on autonomous Neural ODEs h˙=fθ​(h) with saturating activations (tanh, sigmoid, etc.): if $q…

Comparing Physics-Informed and Neural ODE Approaches for Modeling Nonlinear Biological Systems: A Case Study Based on the Morris-Lecar Model

Nikolaos M. Matzakos, Chrisovalantis Sfyrakis

Physics-Informed Neural Networks (PINNs) and Neural Ordinary Differential Equations (NODEs) represent two distinct machine learning frameworks for modeling nonlinear neuronal dynam…
