Understanding Predictability of Bio-Signals using Genetic Algorithms and Sample Entropy

چکیده
Entropy methods (approximate and sample entropy) have been studied to measure the complexity or predictability of finite length time series. The identification of parameters of this entropy family is indispensable task to enable the measure of predictability of time-series data. So far, there have been no general rules to select these parameters; they rather depend on particular problems. In this paper, we introduce a genetic-algorithm based entropy method which optimally selects these parameters in the sense that the discrimination between healthy and pathologic group’s entropy is maximized. Key-Words: Bio-signals; Genetic algorithms; Sample entropy.

Time-Shift Multiscale Entropy Analysis of Physiological Signals
Abstract: Measures of predictability in physiological signals using entropy measures have been widely applied in many areas of research. Multiscale entropy expresses different levels of either approximate entropy or sample entropy by means of multiple factors for generating multiple time series, enabling the capture of more useful information than using a scalar value produced by the two entrop...
متن کاملResearch of Blind Signals Separation with Genetic Algorithm and Particle Swarm Optimization Based on Mutual Information
Blind source separation technique separates mixed signals blindly without any information on the mixing system. In this paper, we have used two evolutionary algorithms, namely, genetic algorithm and particle swarm optimization for blind source separation. In these techniques a novel fitness function that is based on the mutual information and high order statistics is proposed. In order to evalu...
