Some Examples of Visualization in Data Mining
by
Bruce Golden
R. H. Smith School of Business
University of Maryland
In this paper, we discuss two related models of data visualization.
In the first model, we assume the data are provided in adjacency
format, as is frequently the case in practice. As an example,
individuals who buy item A are likely to buy or consider buying
items B, C and D also. We present a simple technique for
obtaining distance measures between data points. Armed with
the resulting distance matrix, we show how Sammon maps can be
used to visualize the data points. An application to the college
selection process is discussed in detail.
In the second model, we focus on group decision making and
demonstrate the utility of visualization in this application area.
Keywords: Visualization; Sammon map; Multidimensional scaling;
