Reduced-order modeling using Dynamic Mode Decomposition and Least Angle Regression
John Graff, Xianzhang Xu, Francis D. Lagor +1
Dynamic Mode Decomposition (DMD) yields a linear, approximate model of a system's dynamics that is built from data. We seek to reduce the order of this model by identifying a reduc…
