| Abstract: | A sequential procedure for mapping the minimal spanning tree (MST) of an h-dimensional data set to 2-dimensional space is proposed. It is shown that both global and local structure are preserved well. The mapping is illustrated with the Iris data. |
| Keywords: | Non-linear mapping minimal spanning tree exploratory data analysis pattern recognition local structure global structure |
