Deep State Space Models for Nonlinear System Identification
share
An actively evolving model class for generative temporal models developed in the deep learning community are deep state space models (SSMs) which have a close connection to classic SSMs. In this work six new deep SSMs are implemented and evaluated for the identification of established nonlinear dynamic system benchmarks. The models and their parameter learning algorithms are elaborated rigorously. The usage of deep SSMs as a black-box identification model can describe a wide range of dynamics due to the flexibility of deep neural networks. Additionally, the uncertainty of the system is modelled and therefore one obtains a much richer representation and a whole class of systems to describe the underlying dynamics.
