Experimental-PGNNs

In this project, we present two applications of Physics-Guided Neural Networks (PGNN) and illustrate their advantages in theory by solving Poisson’s and Burger’s partial differential equations. The proposed formulas describe various real-world processes and are widely used in the area of applied mathematics.
