| Summary : Dimension Reduction with Dynamic CUR
|
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.
