Want to know what Dynamic Mode Decompositions are? This video gives an introduction to dynamic mode decomposition (DMD) in signal processing. We compare the method with other methods, such as Fourier Series and Principle Component Analysis (PCA), where we see that DMD gives custom data driven bases for your signal, while also exploiting the dynamic content of your signal.
