1 code implementation15 Sep 2022 Blake Bullwinkel, Dylan Randle, Pavlos Protopapas, David Sondak

Solutions to differential equations are of significant scientific and engineering relevance.

Port-Hamiltonian Neural Networks for Learning Explicit Time-Dependent Dynamical Systems

1 code implementation16 Jul 2021 Shaan Desai, Marios Mattheakis, David Sondak, Pavlos Protopapas, Stephen Roberts

In this study, we address the challenge of learning from such non-autonomous systems by embedding the port-Hamiltonian formalism into neural networks, a versatile framework that can capture energy dissipation and time-dependent control forces.

Unsupervised Learning of Solutions to Differential Equations with Generative Adversarial Networks

1 code implementation21 Jul 2020 Dylan Randle, Pavlos Protopapas, David Sondak

This work develops a novel method for solving differential equations with unsupervised neural networks that applies Generative Adversarial Networks (GANs) to \emph{learn the loss function} for optimizing the neural network.

Solving Differential Equations Using Neural Network Solution Bundles

no code implementations17 Jun 2020 Cedric Flamant, Pavlos Protopapas, David Sondak

The time evolution of dynamical systems is frequently described by ordinary differential equations (ODEs), which must be solved for given initial conditions.
