Dynamic Mode Decomposition based on Bootstrapping Extended Kalman Filter Application to Noisy data

ORAL

Abstract

In this study, dynamic mode decomposition (DMD) based on bootstrapping extended Kalman filter is proposed for time-series data. In this framework, state variables ($x$ and $y$) are filtered as well as the parameter estimation ($a_{ij}$) which is conducted in the conventional DMD and the standard Kalman-filter-based DMD. The filtering process of state variables enables us to obtain highly accurate eigenvalue of the system with strong noise. In the presentation, formulation, advantages and disadvantages are discussed.
