| 摘要: |
| 采用近似熵和样本熵，分别对三种不同思维任务产生的脑电信号进行特征提取，并将其特征进行比较分析，结果显示不同思维作业脑电信号的样本熵的变化幅度明显大于近似熵。近似熵和样本熵作为非线性动力学的统计方法为思维作业脑电信号特征提取提供了一种新的途径。 |

| Abstract: |
| Two new methods of nonlinear dynamics—approximate entropy and sample entropy were used to extracted to the EEG produced of three different mental tasks feature, and also the features were compared and analyzed.Results showed that the changing range of the sample entropy exceeded the approximate entropy of different mental tasks EEG. The approximate entropy and the sample entropy provide a new way to extacted features on mental task EEG . |
