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

Abstract

The new classification method was proposed where the multi-dimensional data set can be easily classified visually. There, a phase distance on the spherical surface between the label data was computed and the dendrogram was constructed using this spherical surface distances among the labels. Here, based on this constructed dendrogram, the classification of the cluster group on the spherical surface based on the label data was classified and colored. As for this way, it is possible to apply to a variety of data set. However, first, the AES spectrum (the chemical analysis data) was successfully classified and colored. Other examples will be also included for the presentation.
