An incremental approach to online dynamic mode decomposition for time-varying systems with applications to EEG data modeling
Electrical and Computer Engineering Department, Michigan State University, East Lansing, MI 48824, USA |
Dynamic Mode Decomposition (DMD) is a data-driven technique to identify a low dimensional linear time invariant dynamics underlying high-dimensional data. For systems in which such underlying low-dimensional dynamics is time-varying, a time-invariant approximation of such dynamics computed through standard DMD techniques may not be appropriate. We focus on DMD techniques for such time-varying systems and develop incremental algorithms for systems without and with exogenous control inputs. We build upon the work in [
Keywords:
Data-driven dynamics,
dynamic mode decomposition,
time-varying systems,
incremental algorithms.
