%description
Methods for building self-organizing maps (SOMs) with a number of
distinguishing features such automatic centroid detection and cluster
visualization using starbursts.  For more details see the paper "Improved
Interpretability of the Unified Distance Matrix with Connected Components"
by Hamel and Brown (2011) in <ISBN:1-60132-168-6>.  The package provides
user-friendly access to two models we construct: (a) a SOM model and (b) a
centroid based clustering model. The package also exposes a number of
quality metrics for the quantitative evaluation of the map, Hamel (2016)
<doi:10.1007/978-3-319-28518-4_4>.  Finally, we reintroduced our fast,
vectorized training algorithm for SOM with substantial improvements. It is
about an order of magnitude faster than the canonical, stochastic C
implementation <doi:10.1007/978-3-030-01057-7_60>.
