摘要: 提出一种基于相空间重构脑电信号来计算脑电近似熵和信息熵的新方法.实验计算结果表明,癫痫患者脑电和正常人脑电的近似熵和信息熵随相空间嵌入维数的变化有明显的不同.
关键词: 脑电, 相空间, 近似熵, 信息熵
Abstract: Based on the reconstruction of EEG in phase space, a novel algorithm for calculating the approximate entropy and the information entropy of EEG is proposed.The calculated results show that, there are significant differences between epileptic EEG and normal EEG in the variations in approximate entropy and information entropy.
Key words: electroencephalogram (EEG), phase space, approximate entropy, information entropy
