%description
A wrapper around the LIBLINEAR C/C++ library for machine learning
(available at <https://www.csie.ntu.edu.tw/~cjlin/liblinear/>). LIBLINEAR
is a simple library for solving large-scale regularized linear
classification and regression. It currently supports L2-regularized
classification (such as logistic regression, L2-loss linear SVM and
L1-loss linear SVM) as well as L1-regularized classification (such as
L2-loss linear SVM and logistic regression) and L2-regularized support
vector regression (with L1- or L2-loss). The main features of LiblineaR
include multi-class classification (one-vs-the rest, and Crammer & Singer
method), cross validation for model selection, probability estimates
(logistic regression only) or weights for unbalanced data. The estimation
of the models is particularly fast as compared to other libraries.
