WebHMM-based divisive clustering (Butler, 2003) is a “reverse” approach of HMM-agglomerative clustering, starting with one cluster or model of all data points and recursively splitting the most appropriate cluster. The process continues until a stopping criterion (pre-defined number K of clusters or models) is achieved.
