The classification of the chain-link and other data by spherical SOM

A new classification method which can visualize a multidimensional data set was proposed. There, phase distances on the spherical surface among the label data was computed. Using these distances, a dendrogram can be constructed. Here, using the constructed dendrogram, the colored classification of the cluster group on the spherical surface based on the label data was carried out. This method can be applied to various data. Here, the method was applied to the chain-link problem which can be considered as difficult for the representation and to the problem of the separation of the random number planes which were piled up to the direction of the height.
