How can DMD be used for analyzing chemical oscillations and pattern formation in reaction-diffusion systems?

Jul 14, 2020 ... Dynamic mode decomposition (DMD) is a purely data-driven and equation-free technique for reduced-order modeling of dynamical systems and fluid flow.

We propose a modal decomposition algorithm to perform the analysis using finite-length data sequences generated from a nonlinear system. We propose a novel change-point detection method based on online Dynamic Mode Decomposition with control (ODMDwC). Leveraging ODMDwC's ability to find and ... Nov 13, 2019 ...
