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. ...
The common spatial pattern (CSP) algorithm is efficient and accurate for channels selection and features extraction for electroencephalogram (EEG) signals classification. The CSP algorithm is usually applied on a subject-by-subject basis by measuring only intra-subject variations for selecting the most ...
This type of algorithm is called the time-frequency common spatial pattern. CSP is basically a two-class feature extraction algorithm and is not designed for multiclass mode. Ref. [32] is a study that has generalized this tool from two-class to multiclass. The method of generalization of ...
The Common Spatial Pattern (CSP) algorithm is an effective and popular method for classifying 2-class motor imagery electroencephalogram (EEG) data, but its effectiveness depends on the subject-specific frequency band.

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...
The common spatial patterns (CSP) algorithm is often used in BCI. In this work we investigate how the CSP algorithm generalizes when using small training sets, how the performance changes over time, and how well CSP generalizes over persons. Our results indicate that the CSP algorithm severely ...
Although Common spatial pattern (CSP) is a mostly used algorithm for classification of EEG in brain-computer interface (BCI), which has poor frequency selectivity. To address this problem, a constant-bandwidth Butterworth filters bank was utilized for frequency decomposition. Then, our novel feature...
