In this paper a new algorithm is proposed for fast discriminative training of hidden Markov models (HMMs) based on minimum classification error (MCE). The algorithm is able to train acoustic models in a few iterations, thus overcoming the slow training speed typical of discriminative training methods based on gradient-descendent. The algorithm tries to cancel the gradient of the objective funct...

In this paper we suggest monitoring ecosystems’ characteristics in negotiation environments, such as the diversity of the organizations’ working areas, which can be used for recommendation for the whole ecosystem to promote the entrance of new organizations or the recommendation of adapting the organizations for improving their performance. We will see the connection of performance and diversit...

This paper describes a new approach to solving the vehicle route problem with Multiple Trips. The proposed algorithm (IVNDS) is based on the Iterative Local Search meta-heuristic which uses two consecutive Variable Neighbourhood Descendent (VND) procedures in the improvement phase. The VND procedures are differentiated by the search spaces they explore. The first VND performs moves in routes of...

We study three-point celestial amplitudes in Minkowski space for massless scalars, photons, gluons, and gravitons. The corresponding scattering the plane wave basis vanish generic momenta due to momentum conservation. However, delta function conservation has support soft colinear regions, contributes Mellin shadow integrals that give non-zero amplitudes. show with incoming (outgoing) particles ...

Herpes zoster, the latent descendent of the varicella zoster virus, commonly is seen in clinical practice. Healthcare providers must recognize and treat the virus to decrease the incidence of postherpetic neuralgic pain syndrome. Treatment with an antiviral medication regimen should be initiated rapidly for patients who have had lesions for up to 72 hours. Acyclovir has been the treatment of ch...

GGobi is a direct descendent of a data visualization system called XGobi that has been around since the early 1990’s. GGobi’s new features include multiple plotting windows, a color lookup table manager, and an XML (Extensible Markup Language) file format for data. Perhaps the biggest advance is that GGobi can be easily extended, either by being embedded in other software or by the addition of ...

W hy do people work? Economic theory generally, and the principal– agent model specifically, emphasize the role of material incentives. The standard assumption is that people work hard only if they receive monetary compensation for doing so. However, a substantial body of evidence contradicts the standard economic model. Many salaried academics, for example, work diligently year after year, con...
