Computation of spectral properties of Koopman operators associated with discrete-time autonomous dynamical systems. Dynamic mode decomposition (DMD) is a dimensionality reduction algorithm developed by Peter J. Schmid and Joern Sesterhenn in 2008. We develop an iterative approximation algorithm which couples the EDMD with a trainable dictionary represented by an artificial neural network. Spectral decomposition of the Koopman operator is attracting attention as a tool for the analysis of nonlinear dynamical systems. Dynamic mode decomposition.
