Physics-informed neural networks for solving Gray-Scott systems

Date: Tuesday 14 June 2022 – 14:00 (Europe/London)
Speaker: Prof Salvatore Cuomo, Associate Professor of Numerical Analysis, University of Naples Federico II


A physics-informed neural network (PINN) is employed to approximate the solution of nonlinear partial differential equation systems. In this talk, we present an approach for solving different configurations for the Gray-Scott, a reaction-diffusion system that involves an irreversible chemical reaction between two reactants. Computational results show that the PINN can successfully provide an approximated solution in a variety of conditions, also reproducing the characteristic Turing patterns in the unstable region of the model's parameter space, through a supervised approach that relies on a finite difference method (FDM).
