Abstract High dimensional data analysis poses some interesting and counter intuitive problems. One of this problems is, that some clustering algorithms do not work or work only very poorly if the dimensionality is high enough. The reason for this is an effect called distance concentration. In this paper, we show that the effect can be countered for prototype based clustering algorithms by using a clever alteration of the distance function. We show the success of this process by applying (but not restricting) it on FCM. A useful side effect is, that our method can also be used to estimate the number of clusters in a data set.
