%description
Dynamic CUR (dCUR) boosts the CUR decomposition (Mahoney MW., Drineas P.
(2009) <doi:10.1073/pnas.0803205106>) varying the k, the number of columns
and rows used, and its final purposes to help find the stage, which
minimizes the relative error to reduce matrix dimension. The goal of CUR
Decomposition is to give a better interpretation of the matrix
decomposition employing proper variable selection in the data matrix, in a
way that yields a simplified structure. Its origins come from analysis in
genetics. The goal of this package is to show an alternative to variable
selection (columns) or individuals (rows). The idea proposed consists of
adjusting the probability distributions to the leverage scores and
selecting the best columns and rows that minimize the reconstruction error
of the matrix approximation ||A-CUR||. It also includes a method that
recalibrates the relative importance of the leverage scores according to
an external variable of the user's interest.
