Sparse identification of nonlinear dynamical systems(SINDy) is a recently presented framework in the reverse engineering field. It soon gains general interests due to its interpretability and efficiency. Error processing, as an important issue in the SINDy framework, yet remains to be an open problem. To date, literature about error processing focuses on data processing methods which aim to improve the accuracy of data. However, the relationship between data and the identification framework is… Expand

The proposed abrupt-SINDy architecture provides a new paradigm for the rapid and efficient recovery of a system model after abrupt changes, and shows that sparse updates to a previously identified model perform better with less data, have lower runtime complexity, and are less sensitive to noise than identifying an entirely new model.
