fPINNs: Fractional Physics-Informed Neural Networks [PDF]

open access: yesSIAM Journal on Scientific Computing, 2019
Physics-informed neural networks (PINNs) are effective in solving integer-order partial differential equations (PDEs) based on scattered and noisy data. PINNs employ standard feedforward neural networks (NNs) with the PDEs explicitly encoded into the NN using automatic differentiation, while the sum of the mean-squared PDE-residuals and the mean ...

Discontinuity Computing Using Physics-Informed Neural Networks

open access: yesJournal of Scientific Computing, 2022
Simulating discontinuities is a long standing problem especially for shock waves with strong nonlinear feather. Despite being a promising method, the recently developed physics-informed neural network (PINN) is still weak for calculating discontinuities compared with traditional shock-capturing methods.

Quantum Physics Informed Neural Networks

open access: yesThe 53rd International Conference on Parallel Processing Workshops
In this study, the PennyLane quantum device simulator was used to investigate quantum and hybrid, quantum/classical physics-informed neural networks (PINNs) for solutions to both transient and steady-state, 1D and 2D partial differential equations. The comparative expressibility of the purely quantum, hybrid and classical neural networks is discussed ...

Physics informed neural networks for triple deck [PDF]

open access: yesAircraft Engineering and Aerospace Technology, 2022
Purpose This paper aims to introduce physics-informed neural networks (PINN) applied to the two-dimensional steady-state laminar Navier–Stokes equations over a flat plate with roughness elements and specified local heating. The method bridges the gap between asymptotics theory and three-dimensional turbulent flow analyses, characterized by high costs ...

Physics Informed Neural Network for Option Pricing

open access: yesCoRR, 2023
We apply a physics-informed deep-learning approach the PINN approach to the Black-Scholes equation for pricing American and European options. We test our approach on both simulated as well as real market data, compare it to analytical/numerical benchmarks.
