New physics-informed method adaptively constructs functional representations for complex equations

Researchers have developed a novel Physics-Informed Method of Group Data Handling (PI-GMDH) that adaptively constructs functional representations for solving complex physical equations. This method progressively builds representations during the solution process, evaluating candidate functional directions and optimizing coefficients. Demonstrated on the incompressible Navier-Stokes equations using a Taylor Green benchmark, PI-GMDH achieved highly accurate results with a reduced number of active functions compared to traditional physics-informed neural networks and Kolmogorov-Arnold Networks. AI
