Claim 4:
5. The method of claim 1, wherein applying entry-wise processing to the second matrix comprises selecting a second processing pipeline, the second processing pipeline comprising:
applying Principal Component Analysis (PCA) to the second matrix and producing a third matrix as a projection in a space of Principal Components of the second matrix;
applying resampling and a second truncation to the third matrix to produce a resampled truncated matrix, wherein the resampling comprises resampling entry-wise the second matrix and the second truncation comprises removing from the third matrix a number of entries as a function of a variance of the entries of the third matrix;
computing an entry-wise norm vector and an entry-wise sign-vector of the resampled truncated matrix, and producing a vector equal to a scalar product of the entry-wise norm vector times the entry-wise sign-vector; and
performing KDE on the produced vector to produce at least one estimated kernel density of the produced vector, wherein the at least one estimated kernel density is indicative of the state of the dynamical system.
