Abstract:


The Self-Organizing Map is one of most prominent tools for the analysis
and visualization of high-dimensional data.
We propose a novel visualization technique for
Self-Organizing Maps which can be displayed either as a vector
field where arrows point to cluster centers, or as
a plot that stresses cluster borders. A parameter is
provided that allows for visualization of the cluster structure at different levels of detail.
Furthermore, we present a number of experimental results using
standard data mining benchmark data.
