a) Dynamic mode dynamic (DMD) can be thought of as an ideal combination of spatial dimensionality-reduction techniques, such as the principal component analysis (PCA), with Fourier transforms in time.

b) Independent component analysis (ICA) is a method for finding underlying factors or components from multivariate (multi-dimensional) statistical data.

c) Reduce the dimensionality of a data set by finding a new set of variables, smaller than the original set of variables.

d) Singular value decomposition (SVD) is a method for finding underlying factors or components from multivariate (multi-dimensional) statistical data.
