Paper Abstract

We have studied the memory effect on typical complex measures such as fractal dimension and entropy based on the sample entropy algorithm. First, it is shown how is the stochastic process of complex measures (a local fractal dimension and a local sample entropy) for real EEG data from healthy people and demented ones. The features of multi-scale entropy for EEGs are also shown. Then, the natures of complex measures for theoretical models such as Brownian oscillators and stochastic complex Ginzburg-Landau equation are exhibited. The memory effects on the complex measures for real EEG data are discussed by comparing theoretical models.
