The package provides\nuser-friendly access to two models we construct: (a) a SOM\nmodel and (b) a centroid based clustering model. The package\nalso exposes a number of quality metrics for the quantitative\nevaluation of the map, Hamel (2016)\n. Finally, we reintroduced\nour fast, vectorized training algorithm for SOM with\nsubstantial improvements.
