"Misclassification check of iris reference data by spherical SOM, and LVQ method"

Abstract

Iris data is composed of setosa 50 plants, vergicolor 50 plants, virginica 50 plants, and total 150 plants. This iris data is used as basic benchmark data of cluster classification. However, when analyzing with spherical SOM, misclassification was found at the boundary between vergicolor and viginica. For the analysis, the distance calculation on the sphere, and the LVQ method were used.　Further error sum of squares was also used as an aid.
