Abstract: Biomedical data sets often have mixed categorical and numerical
types, where the former represent semantic information on the objects and the
latter represent experimental results. We present the BILCOM algorithm for
`Bi-Level Clustering of Mixed categorical and numerical data types'. BILCOM
performs a pseudo-Bayesian process, where the prior is categorical clustering.
BILCOM partitions biomedical data sets of mixed types, such as hepatitis,
thyroid disease and yeast gene expression data with Gene Ontology
