Abstract :
Results are presented concerning the problem of identifying temporal structure in composite sources. An alternative class of techniques for identifying the underlying structure of a SCS (structured composite source) from its estimated transition matrix is proposed. These techniques are postulated directly with respect to the discrete elements of a Markov chain and allow for non-hierarchical and hierarchical decomposition. The general structure of this class is developed, and examples based on a specific clustering algorithm are discussed
