摘要 针对不同思维运动中EEG信号识别,提出了一种基于自回归模型参数和支持向量机的识别方法.针对2008年BCI CompetitionⅣData sets 2a数据集中想象左右手运动的两类思维运动脑电信号,运用自回归模型进行特征提取,支持向量机进行特征分类.采用不同的核函数进行分类对比实验,该识别方法的正确识别率达到75%. 针对不同思维运动中EEG信号识别,提出了一种基于自回归模型参数和支持向量机的识别方法.针对2008年BCI CompetitionⅣData sets 2a数据集中想象左右手运动的两类思维运动脑电信号,运用自回归模型进行特征提取,支持向量机进行特征分类.采用不同的核函数进行分类对比实验,该识别方法的正确识别率达到75%.
