共空间模式CSP 共空间模式(Common Spatial Pattern, CSP)是一种对两分类任务下的空域滤波特征提取算法,能够从多通道的脑机接口数据里面提取出每一类的空间分布成分。公共空间模式算法的基本原理是利用矩阵的对角化,找到一组最优空间滤波器进行投影,使得两类信号的方差值差异最大化,从而得到具有较高区分度的特征向量。

11.3.4 Weighted common spatial pattern A novel approach named weighted common spatial pattern in Fig. 11.2 is proposed. In order not to conflict with windowed-CSP and wavelet-CSP, weighted CSP can be identified with WgtCSP. This method is efficient and simultaneously simple for extracting robust...
As one of the most commonly used algorithms in the field of feature extraction, common spatial pattern (CSP) has a good effect on multichannel electroencephalogram (EEG) signal classification, especially for motor imagery-based signals. However, the formulation of the conventional CSP based on the ...
