Visualization of similarities and dissimilarities in rules using MDS

This paper proposes a visualization approach to show the similarity relations between rules based on multidimensional scaling (MDS), which assign a two-dimensional cartesian coordinate to each data point from the information about similiaries between this data and others data. First, semantic and synctatic similarities of rules are obtained after rules are induced from a datasets. Then, MDS is applied to each similarity. MDS visualizes the difference between semantic and synctatic simliarites. This method was evaluated on two medical data sets, whose experimental results show that knowledge useful for domain experts could be found.
