  • Denny and David McG. Squire, Visualization of Cluster Changes by Comparing Self-Organizing Maps, In Tu Bao Ho, David Cheung and Huan Li eds., The Ninth Pacific-Asia Conference on Knowledge Discovery and Data Mining (PAKDD '05), Hanoi, Vietnam, No. 3518 in Lecture Notes in Computer Science, pp. 410-419, Springer-Verlag, 18-20 May 2005.

    In this paper we introduce Self-Organizing Map-based techniques that can reveal structural cluster changes in two related data sets from different time periods in a way that can explain the new result in relation to the previous one. These techniques are demonstrated using a real-world data set from the World Development Indicators database maintained by the World Bank. The results verify that the methods are capable of revealing changes in cluster strucure and membership, corresponding to known changes in economic fortunes of countries.
