| Abstract: | There are two concepts of neural networks which became very popular: multi layer perceptrons (MLP) and self organizing feature maps (SOFM). The advantages of the MLP for segmentation purposes are already analysed by Hruschka/Natter in detail. In this article we evaluate the usefulness of the second approach (SOFM) for cluster analysis. Based upon the results of a Monte-Carlo simulation we show that the Ward algorithm should be preferred to identify the number of clusters. But the application of a SOFM seems to be superior to k-means if observations are assigned to clusters. |
