Common spatial pattern (CSP) method is widely used in brain machine interface (BMI) applications to extract features from the multichannel neural activity through a set of spatial projections. These spatial projections minimize the Rayleigh quotient (RQ) as the objective function, which is the ...

Common spatial pattern (CSP) has been most popularly applied to motor-imagery (MI) feature extraction for classification in brain–computer interface (BCI) application. Successful application of CSP depends on the filter band selection to a large degree. However, the most proper band is typically ...
A common cutoff order that would work for all the subjects turned out to be about 25. The SVARGS algorithm was then run on all of the epochs with a fixed model order of 25 which at 256 Hz corresponds to a history of about 100 ms. This resulted in 39 sparse VAR models per video ...
Entropic optimal transport In order to disambiguate this optimization problem while opening the door to fast parallel solvers, a common strategy is to add a smooth, strictly convex penalty to the linear objective ⟨π,C⟩ of (21) [33, 68]. The entropy-regularized optimal transport problem ...
