Regularized dynamic mode decomposition algorithm for time sequence predictions

open access: goldTheoretical and Applied Mechanics Letters
Dynamic mode decomposition (DMD) aims at extracting intrinsic mechanisms in a time sequence via linear recurrence relation of its observables, thereby predicting later terms in the sequence. Stability is a major concern in DMD predictions.

Large Eddy Simulation and Dynamic Mode Decomposition of Turbulent Mixing Layers

open access: yesApplied Sciences, 2021
Turbulent mixing layers are canonical flow in nature and engineering, and deserve comprehensive studies under various conditions using different methods. In this paper, turbulent mixing layers are investigated using large eddy simulation and dynamic mode

Constrained Dynamic Mode Decomposition

open access: yesIEEE Transactions on Visualization and Computer Graphics, 2022
Frequency-based decomposition of time series data is used in many visualization applications. Most of these decomposition methods (such as Fourier transform or singular spectrum analysis) only provide interaction via pre- and post-processing, but no means to influence the core algorithm.

Towards an Adaptive Dynamic Mode Decomposition

open access: yesResults in Control and Optimization, 2022
Dynamic Mode Decomposition (DMD) is a tool that creates an approximate model from spatio-temporal data. We have developed an architecture of this tool that will adapt to the data from a given problem by leveraging time delay coordinates, projections, and

Visualization and selection of Dynamic Mode Decomposition components for unsteady flow

open access: yesVisual Informatics, 2021
Dynamic Mode Decomposition (DMD) is a data-driven and model-free decomposition technique. It is suitable for revealing spatio-temporal features of both numerically and experimentally acquired data.

Dynamic-mode decomposition and optimal prediction [PDF]

open access: yesPhysical Review E, 2021
The Dynamic-Mode Decomposition (DMD) is a well established data-driven method of finding temporally evolving linear-mode decompositions of nonlinear time series. Traditionally, this method presumes that all relevant dimensions are sampled through measurement.
