Alternative representations of the SOM general clustering of patterns Alternative representations of the SOM general clustering of the data with projection of the SOM results in 2D space (a). This graphic can be interactively manipulated (rotation, panning, zooming, walkthrough) and be viewed in 3D space. The output of the SOM (the similarity coding extracted from the computational analysis) can be projected on a geographic map, to display the common characteristics of the countries according to the multivariate attributes (b).
