Ordinal Patterns, Entropy, and EEG
Karsten Keller, Anton M. Unakafov, Valentina A. Unakafova · Entropy · 2014
In this paper we illustrate the potential of ordinal-patterns-based methods for analysis of real-world data and, especially, of electroencephalogram (EEG) data. We apply already known (empirical permutation entropy, ordinal pattern distributions) and new (empirical conditional entropy of ordinal patterns, robust to noise empirical permutation entropy) methods for measuring complexity, segmentation and classification of time series.
