%description
Splits data into Gaussian type clusters using the Cross-Entropy Clustering
('CEC') method. This method allows for the simultaneous use of various
types of Gaussian mixture models, for performing the reduction of
unnecessary clusters, and for discovering new clusters by splitting them.
'CEC' is based on the work of Spurek, P. and Tabor, J. (2014)
<doi:10.1016/j.patcog.2014.03.006>.
