Abstract: Summary Methods of cluster analysis (unsupervised classification) can help you in order to “Finding groups in data”, so the suitable title of a book from Kaufman and Rousseeuw (1990). The intelligent clustering technique proposed here appears to be motivated by practical problems of analyzing mixed data. One way to deal with such problems is downgrading all data to the lowest scale level, that is, downgrading to categories without any information about their order. This new clustering technique based on dual scaling is presented in the simplest fashion possible for finding two groups (clusters) in data and for visualizing them, respectively. It is compared with well-known model-based clustering techniques. In the conclusion variations of improvement of the method are proposed.
