アブストラクト
Dynamic mode decomposition (DMD) provides a data-driven approach to analyzing dynamical systems and has been applied to various systems. In this study, we performed DMD and Extended DMD analysis for elementary cellular automata (ECA) as a typical example of finite-state spatially-extended dynamical systems. ECA can exhibit various dynamics including chaotic ones, and thus be useful for examining the validity of the results obtained by DMD.
