NUMERICAL SPECTRUM LINKING: IDENTIFICATION OF GOVERNING PDE VIA KOOPMAN-CHEBYSHEV APPROXIMATION
ICASSP 2026poster
A numerical framework is proposed for identifying partial differential equations (PDEs) governing dynamical systems directly from their observation data using Chebyshev polynomial approximation. In contrast to data-driven approaches such as dynamic mode decomposition (DMD), which approximate the Koo…
