Ordinal symbolic analysis and its application to biomedical recordings

Abstract

Ordinal symbolic analysis opens an interesting and powerful perspective on time-series analysis. Here, we review this relatively new approach and highlight its relation to symbolic dynamics and representations. Our exposition reaches from the general ideas up to recent developments, with special emphasis on its applications to biomedical recordings. The latter will be illustrated with epilepsy data.

Keywords: ordinal patterns; permutation entropy; symbolic dynamics; time-series analysis.
