This paper proposes two common spatial pattern (CSP) filters for EEG-based regression problems in BCI, which are extended from the CSP filter for classification, by making use of fuzzy sets. other hand, spatial filtering is a computationally efficient approach, which permits to remove artifacts by exploiting information about their spatial distribution over the EEG sen- sors (Lagerlund et al1997). Three independent components analysis (ICA) algorithms (Infomax, FastICA and SOBI) have been compared with other preprocessing methods in order to find out whether and to which extent spatial filtering of EEG data can improve single trial classification accuracy. We demonstrate that spatial filters for multichannel EEG effectively extract discriminatory information from two populations of single-trial EEG, recorded during left- and right-hand movement imagery. Saa and Cetin (2012) proposed the Filter Bank Common Spatial Pattern (FBCSP). After filtering the original EEG signal with a set of filters, the CSP method is used to extract features on each filtered frequency band.

This paper proposes two common spatial pattern (CSP) filters for EEG-based regression problems in BC!, which are extended from the CSP filter for classification, by using fuzzy sets.
