Processus Aléatoires Dans Des C ˆ Ones — 16 Mai 2014

Dans cet exposé, on s’intéresse au taux exponentiel de décroissance de la probabilité qu’une marche aléatoire avec dérive reste dans un cône fixé jusqu’à l’instant n. Pour une marche aléatoire possédant tous les moments exponentiels, et dont le support satisfait une condition simple de non-dégénérescence vis-à-vis du cône considéré, nous démontrons que le taux exponentiel est donné par le minim...

Peste des Petits Ruminants Virus in Heilongjiang Province, China, 2014

During March 25-May 5, 2014, we investigated 11 outbreaks of peste des petits ruminants in Heilongjiang Province, China. We found that the most likely source of the outbreaks was animals from livestock markets in Shandong. Peste des petits ruminants viruses belonging to lineages II and IV were detected in sick animals.

Adapted Extended Baum-Welch Transformations

The discrimination technique for estimating parameters of Gaussian mixtures that is based on the Extended Baum-Welch transformations (EBW) has had significant impact on the speech recognition community. In this paper we introduce a general definition of a family of EBW transformations that can be associated with a weighted sum of updated and initial models. We compute a gradient steepness measu...

Generalized Baum-Welch Algorithm and its Implication to a New Extended Baum-Welch Algorithm

This paper describes how we can use the generalized BaumWelch (GBW) algorithm to develop better extended BaumWelch (EBW) algorithms. Based on GBW, we show that the backoff term in the EBW algorithm comes from KL-divergence which is used as a regularization function. This finding allows us to develop a fast EBW algorithm, which can reduce the time of model space discriminative training by half, ...
