common spatial patterns
is there any basic tutorial on common spatial patterns and how does it work?
We don't provide a basic tutorial about common spatial patterns. Basically, CSP works by common diagonalization of covariance matrices for a pair of classes; common eigenvectors respresent CSP components.
To compute CSP components, first compute separate covariance matrices C1 and C2 from the data from each class. Then, compute common eigenvalues and eigenvectors from the two covariance matrices (in Matlab, use [V,D]=eig(C1,C2)). The columns of V are the common eigenvectors of C1 and C2, i.e. projection vectors for the CSP components.
