We discuss maximum a posteriori estimation of continuous density hidden Markov models (CDHMM). The classical MLE reestimation algorithms, namely the forward-backward algorithm and the segmental k-means algorithm, are expanded and reestimation formulas are given for HMM with Gaussian mixture observation densities. Because of its adaptive nature, Bayesian learning serves as a unified approach for...

To identify critical sediment sources in large catchments, using easily available terrain information at a regionalscale, a methodology was developed to obtain a qualitative assessment necessary for environmental management.Fargas et al method was employed in the research. The study was carried out in one of the sub-basins of Hableh Roodbasin called Dehnamak in the arid and semiarid climate of ...

The present study focussed on the use of Foxtail millet (Setaria italica) along with other flour for production of ready-to-eat snack products using extrusion cooking. The ultimate objective is to add value to millet and other subtropical crops to enable their commercialisation and thereby provide additional livelihood opportunities to the farmers in semi‐arid regions. Composite flours were pre...

The existence of a perfect -factorization of the complete graph with nodes, namely, , for arbitrary even number , is a 40-year-old open problem in graph theory. So far, two infinite families of perfect -factorizations have been shown to exist, namely, the factorizations of and , where is an arbitrary prime number . It was shown in previous work that finding a perfect -factorization of is relate...

This paper treats the isometries of metric spaces of quantum states. We consider two metrics on the set all quantum states, namely the Bures metric and the one which comes from the trace-norm. We describe all the corresponding (nonlinear) isometries and also present similar results concerning the space of all (non-normalized) density operators.
