  • We study clustering algorithms for data with Boolean and categorical attributes. [...] Key Method We develop a robust hierarchical clustering algorithm, ROCK, that employs links and not distances when merging clusters. Our methods naturally extend to non-metric similarity measures that are relevant in situations where a domain expert/similarity table is the only source of knowledge. In addition to presenting detailed complexity results for ROCK, we also conduct an experimental study with real-life as well as…Expand Abstract
