EKF-SINDy: Empowering the extended Kalman filter with sparse identification of nonlinear dynamics
To demonstrate the potential of the approach, we address the identification of a linear non-autonomous system consisting of a shear building model excited by real seismograms, and the identification of a partially observed nonlinear system.
