Researchers have developed a new two-stage training framework for Physics-Informed Neural Networks (PINNs) to address challenges in solving the inverse problem of the 1D Porous Medium Equation (PME). Standard PINN formulations for inverse problems are sensitive to initial guesses, leading to local convergence. The proposed two-stage approach enhances convergence stability and reliably recovers unknown parameters, even with poor initial guesses, offering a more robust alternative to classical methods for complex PME problems.
