Singular layer PINN methods for Burgers' equation

Teng-Yuan Chang, Gung-Min Gie, Youngjoon Hong +1

In this article, we present a new learning method called sl-PINN to tackle the one-dimensional viscous Burgers problem at a small viscosity, which results in a singular interior la…

Semi-analytic PINN methods for boundary layer problems in a rectangular domain

Gung-Min Gie, Youngjoon Hong, Chang-Yeol Jung +1

Singularly perturbed boundary value problems pose a significant challenge for their numerical approximations because of the presence of sharp boundary layers. These sharp boundary…

Singular layer Physics Informed Neural Network method for Plane Parallel Flows

Teng-Yuan Chang, Gung-Min Gie, Youngjoon Hong +1

We construct in this article the semi-analytic Physics Informed Neural Networks (PINNs), called {\em singular layer PINNs} (or {\em sl-PINNs}), that are suitable to predict the sti…

Semi-analytic PINN methods for singularly perturbed boundary value problems

Gung-Min Gie, Youngjoon Hong, Chang-Yeol Jung

We propose a new semi-analytic physics informed neural network (PINN) to solve singularly perturbed boundary value problems. The PINN is a scientific machine learning framework tha…
