Deep State Space Models For Nonlinear System Identification Deepai State space models demonstrate exceptional nonlinear prediction performance, maintaining extremely high accuracy with a minimal parameter scale, and effectively capturing the system’s nonlinear features without divergence in long term prediction tasks. Here, we propose a fast algorithm to learn and forecast nonlinear dynamics from noisy time series data. a key feature of the proposed model is kernel functions applied to projected lines, enabling the fast and efficient capture of nonlinearities in the latent dynamics.

For data assimilation, the notion of linearizing a nonlinear model about a reference state is central to many techniques, such as the extended kalman filter and the tangent linear model used in adjoint equations. In control engineering and system identification, a state space representation is a mathematical model of a physical system that uses state variables to track how inputs shape system behavior over time through first order differential equations or difference equations. The formulas for linearizing nonlinear discrete time state space models are presented without derivation below. they can be derived in the same way as for linearizing nonlinear continuous time models [1].
