Results of the signal decomposition by clustering. Left: Reconstruction of the mode set by clustering the generalized eigenfunctions of ResDMD. The residual shows the error between the observed signal data and all modes before clustering in ResDMD. Signal 1 and Signal 2 correspond to those shown in the left panel of Fig. 1. The blue, and orange lines show the mode set reconstructions by clustering, respectively. Middle: Mode set reconstruction by clustering the eigenfunctions of DMD, plotted in the same way as on the left. Right: Mode set reconstruction by clustering the eigenfunctions of mpEDMD.
