New two-stage PINN approach improves inverse problem solving for porous medium equation

Researchers have developed a novel two-stage training framework for Physics-Informed Neural Networks (PINNs) to address challenges in solving the inverse problem of the 1D Porous Medium Equation. This new approach significantly enhances convergence stability and enables reliable parameter recovery, even with poor initial guesses. The study demonstrates that PINNs offer a flexible and accurate alternative to traditional methods for the 1D PME, with the proposed strategy improving robustness for inverse problems and laying groundwork for more complex applications.
