%description
A way to apply Distance-Based Common Spatial Patterns (DB-CSP) techniques
in different fields, both classical Common Spatial Patterns (CSP) as well
as DB-CSP. The method is composed of two phases: applying the DB-CSP
algorithm and performing a classification. The main idea behind the CSP is
to use a linear transform to project data into low-dimensional subspace
with a projection matrix, in such a way that each row consists of weights
for signals. This transformation maximizes the variance of two-class
signal matrices.The dbcsp object is created to compute the projection
vectors. For exploratory and descriptive purpose, plot and boxplot
functions can be used. Functions train, predict and selectQ are
implemented for the classification step.
