In this paper, we propose an analytically tractable framework that integrates the frame and segment based acoustic modeling techniques. We combine the two approaches by jointly modeling their respective hidden Markov processes. Since the joint process is based on the same mathematical framework, conventional search and training techniques, such as Viterbi and EM algorithms, can be directly appl...

It is well known that HMM is ineffective in modeling the dynamics of speech due to the piecewise stationary and the independent observation assumptions. In this paper, we propose an analytically tractable framework in which the two modeling techniques are combined to reach a jointly optimal decision in both training and recognition. The combination is achieved by coupling the hidden processes f...

This paper describes a novel method that models the correlation between acoustic observations in contiguous speech segments. The basic idea behind the method is that acoustic observations are conditioned not only on the phonetic context but also on the preceding acoustic segment observation. The correlation between consecutive acoustic observations is modeled by polynomial mean trajectory segme...

The effect of clay and chemical cross-linking on the dynamic mechanical properties polyurethane reinforced with different concentrations organically modified montmorillonite is investigated in this study. matrix constituted polytetrahydrofuran soft segment 4,4′-methylenebis(phenyl isocyanate) hard segment. Glycerin was used as crosslinking agent, while Cloisite 30B reinforcing filler. nanocompo...

We address the problem of having insufficient labels in an interactive image segmentation framework, for which most current methods would fail without further user interaction. To minimize user interaction, we use the appearance and boundary information synergistically. Specifically, we perform distribution propagation on the image graph constructed with color features to derive an initial esti...

In this paper an automatic examination robot was developed to improve the process of cancer detection, tumor localization and geometrical shape diagnosis. A uniformly distributed compressive load was applied to the top tissue surface and the resultant mechanical stress was measured that was employed for the tumor diagnosis task. The experimental examinations were performed on the soft tissue of...
