Hierarchical clustering of a mixture model

Webalgorithm based on a multinomial mixture model has been developed[9]. In the rest of the paper our refer ences to HAC will be to the version of HAC used in a likelihood setting as … Webcussed on expressing hierarchical clustering in terms of probabilistic models. For example Ambros-Ingerson et at [2] and Mozer [10] developed models where the idea is to cluster data at a coarse level, subtract out mean and cluster the residuals (recursively). This paper can be seen as a probabilistic interpretation of this idea.
