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。

共空间模式(Common Spatial Pattern, CSP)作为运动想象脑机接口的常用特征提取算法,相信很多接触过此领域的人都知道该算法,CSP的原理以及推导下面这篇博客做出了详细说明: 点此跳转 但是,在RCSP论文[1]中作者给出了不同与上面博客的定义形式,也有必要了解一下,以下为RCSP中对CSP算法的描述的翻译。 (PS:第一次翻...
Common spatial pattern (CSP) is a mathematical procedure used in signal processing for separating a multivariate signal into additive subcomponents which have maximum differences in variance between two windows. This algorithm is mainly used in motor imagery based BCI for processing EEG data. ...
11.3.1 Common spatial pattern The common spatial pattern is widely used for finding discriminative features in EEG-based BCIs. One reason for such popularity to root in its simplicity is taking the variance (the power of the signal) as the main representative of trials. It was firstly introduce...

Common spatial pattern (CSP) is a popular feature extraction method for electroencephalogram (EEG) classification. Most of existing CSP-based methods exploit covariance matrices on a subject-by-subject basis so that inter-subject information is neglected. In this paper we present modifications of CSP...
Common spatial pattern(CSP) algorithm is a successful tool in feature estimate of brain-computer interface(BCI).However,CSP is sensitive to outlier and may result in poor outcomes since it is based on pooling the covariance matrices of trials.In this paper,we propose a simple yet effective appr...
In motor imagery-based Brain Computer Interfaces (BCI), discriminative patterns can be extracted from the electroencephalogram (EEG) using the Common Spatial Pattern (CSP) algorithm. However, the performance of this spatial filter depends on the operational frequency band of the EEG. Thus, setting ...
