%description
A toolbox of fast, native and parallel implementations of various
information-based importance criteria estimators and feature selection
filters based on them, inspired by the overview by Brown, Pocock, Zhao and
Lujan (2012) <https://www.jmlr.org/papers/v13/brown12a.html>. Contains,
among other, minimum redundancy maximal relevancy ('mRMR') method by Peng,
Long and Ding (2005) <doi:10.1109/TPAMI.2005.159>; joint mutual
information ('JMI') method by Yang and Moody (1999)
<https://papers.nips.cc/paper/1779-data-visualization-and-feature-selection-new-algorithms-for-nongaussian-data>;
double input symmetrical relevance ('DISR') method by Meyer and Bontempi
(2006) <doi:10.1007/11732242_9> as well as joint mutual information
maximisation ('JMIM') method by Bennasar, Hicks and Setchi (2015)
<doi:10.1016/j.eswa.2015.07.007>.
