摘要: A new iterative approach for hidden Markov modeling of information sources which aims at minimizing the discrimination (or cross-entropy) between source and model is proposed. This does not require commonly used assumption that to be modeled a process. The algorithm started from estimated by traditional maximum likelihood (ML) alternatively decreases over all probability distributions agree with given measurements models. proposed procedure generalizes Baum ML modeling. shown descent measure its local convergence proved.
