Abstract

In the study of complex systems one maybe faced with experimental data collected on the variables without knowing much about the way in which these variables interact. The parts of such a complex system interact in a norisimple way [l]. Wolfram [2] found that there exists a complex dynamic state which may be even more complex than chaotic motions. Complex systems have been found to have an underlying deterministic model and exhibit chaotic dynamics in some cases, epilepsy in particular [3]. The use of quantitative measures for the analysis of these systems has helped gain better insight into system dynamics. In this article we apply Ziv-Lempel (LZ) complexity and approximate entropy (ApEn) as measures to quantify the regularity in the various epochs of epileptic seizure time-series data.
