DTU Wind and Energy Systems. 27. Identification of large-scale, atmospheric structures using, Dynamic Mode Decomposition. In this paper, we will propose an extension of DMD that exploits low-rank tensor decompositions of potentially high-dimensional data sets. We develop an iterative approximation algorithm which couples the EDMD with a trainable dictionary represented by an artificial neural network. Jan 20, 2021 ... Abstract.
