SOMbrero: SOM Bound to Realize Euclidean and Relational Outputs (R package, available on CRAN)
Résumé
The stochastic (also called on-line) version of the Self-Organising Map (SOM) algorithm is provided. Different versions of the algorithm are implemented, for numeric and relational data and for contingency tables as described, respectively, in Kohonen (2001) , Olteanu & Villa-Vialaneix (2005) and Cottrell et al (2004) . The package also contains many plotting features (to help the user interpret the results) and a graphical user interface based on 'shiny'.
