RECURRENCE QUANTIFICATION ANALYSIS AND PRINCIPAL COMPONENTS IN THE DETECTION OF SHORT COMPLEX SIGNALS

Recurrence plots were introduced to aid in the detection of signals in complicated data series. This effort was taken a step further by the quantification of recurrence plot elements. We now demonstrate the uti lity of combining recurrence quantification analysis with principal co mponents analysis to allow for a probabilistic evaluation of the prese nce of deterministic signals in relatively short data lengths.
