The introduction of the ultimate clustering tool (demo) - the classification by the topologically reserved Spherical Self Organizing Maps (blossom) -

Abstract

The new classification method was proposed where a multidimensional data set was visualized. There, a phase distance on the spherical surface among the label data was computed and a dendrogram was constructed using the distance. Here, the coloring by the classification of the cluster group on the spherical surface based on the label data was carried out based on this constructed dendrogram. By this method, a variety of data can be applied and analyzed. However, the example which was applied to the iris benchmark data and chain-link data are mainly described. A boundary among the clusters was clearly visualized by this coloring method. Here, we demonstrate some examples.
