Example text

The preliminary experiments with real symbolic data sets, done by the author, also confirm the quality of these indexes in the symbolic data case. Cluster Quality Indexes for Symbolic Classification – An Examination 37 The results can be explained by the fact that Hubert and Levine and the Baker and Hubert indexes are based on distance matrices and for them, limitations of symbolic methods, described in section 2, do not exist. Table 3. Comparison of cluster quality indexes for symbolic data – Dynamical clustering.

The situation differs in case of symbolic data. There are no hints in literature which indexes are most appropriate for that kind of data. This paper describes cluster quality indexes that can be used in this case. In the first part clustering methods that can be used for symbolic data and methods designed exclusively for this kind of data are described. The second part presents main groups of cluster quality indexes along with examples of indexes from each group (due to the lack of space only the most frequently used indexes are described).

The problem is formulated as penalized logistic regression, where the labels are only indirectly observed (via the component densities).
