New Flow Map Learning framework models unknown nonlocal PDE systems

Researchers have developed a novel framework called Flow Map Learning (FML) to model unknown nonlocal partial differential equations (PDEs) directly from solution data. This approach bypasses the need to explicitly learn or approximate the complex nonlocal operators. Instead, FML learns the finite-time evolution operator, offering accurate and stable long-time predictions even with limited observation windows. The method has shown success in predicting dynamics for fractional diffusion and wave equations. AI
