Sparse coding aims to model data vectors as sparse linear combinations of basis elements, but a majority related studies are restricted continuous without spatial or temporal structure. A new model-based (MSC) method is proposed provide an effective and flexible framework for learning features from different types: continuous, discrete, categorical, modeling types correlations: temporal. The sp...

Many traffic accidents are caused by drivers with fatigue states. It is important to detect fatigue states of drivers from their eye opening degrees, namely normal, dozing and fatigue. The paper proposes a fatigue state recognition algorithm that combines independent component analysis (ICA) and one-dimensional hidden Markov model (HMM) together. The algorithm firstly does binarisation processi...

Capturing regularities in high-dimensional data is an important problem in machine learning and signal processing. Here we present a statistical model that learns a nonlinear representation from the data that reflects abstract, invariant properties of the signal without making requirements about the kind of signal that can be processed. The model has a hierarchy of two layers, with the first la...

In this paper we present a new method for synthesizing multiple languages with the same voice, using HMM-based speech synthesis. Our approach, which we call HMM-based polyglot synthesis, consists of mixing speech data from several speakers in different languages, to create a speakerand language-independent (SI) acoustic model. We then adapt the resulting SI model to a specific speaker in order ...

The most interesting point however of a model driven approach is the ability to continuously map the model from a platform independent model to (a) more platform specific model(s) through model transformations. This may be performed eithervertically meaning here development of the model or horizontally meaning mapping the model to a different (or supporting) modeling aspect, eg: structural to t...

Inter-organisational applications require improved support from middleware services. This paper analyses the management requirements of multidomain applications, covering both technological domains and organisations (administrative business domains). The analysis leads to a suggested middleware solution for these needs, presenting a group of cooperative, pervasive management services that use a...

the independent model used by meyer and schramm (here after m&s) for determining the age ofelements (chemical evolution) is extended. using new and extended definitions and including parametersignored by m&s, the galactic evolution equations are solved to determine the total duration ofnucleosynthesis,t. to be able to calculate the t t (mean age time for formation of elements to total ...

Infrared spectroscopy provides direct information on the composition of interstellar dust grains, which play a fundamental role in the evolution of interstellar medium ISM, from cold, quiet and low density molecular clouds to warm, active and dense protostellar ones. The determination of these components is fundamental to predict under the appropriate environmental conditions their evolution, i...
