Data-driven system identification using quadratic embeddings of nonlinear dynamics
Stefan Klus, Joel-Pascal Ntwali N'konzi
We propose a novel data-driven method called QENDy (Quadratic Embedding of Nonlinear Dynamics) that not only allows us to learn quadratic representations of highly nonlinear dynami…
