%description
Self-organizing maps with a number of distinguishing features: (1)
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>. (2) Two models of the data: (a) a self organizing
map model, (b) a centroid based clustering model. (3) A number of easily
accessible quality metrics, Hamel (2016)
<doi:10.1007/978-3-319-28518-4_4>.
