Modeling and Simulation of Nonlinear Dynamics Using Physics-Informed Deep Neural Networks

Seid Hosein Pourtakdoust; A. H. Khodabakhsh

Volume 6, Issue 4 , February 2023, Pages 25-36

https://doi.org/10.22034/jtae.2023.6.4.3

Abstract
  Development of Physics-Informed Neural Networks (PINNs) as nonlinear dynamics surrogates is investigated. PINNs are unsupervised neural networks in which the input-output relationship is established via a specific dynamic relationship (differential equation). In this regard, the derivatives are determined ...  Read More
