Abstract We propose a greedy variational method for decomposing non-negative multivariate signal as weighted sum of Gaussians, which, borrowing the terminology from statistics, we refer to Gaussian mixture model. Notably, our has following features: (1) It accepts signals, i.e., sampled functions, histograms, time series, images, etc., input. (2) The can handle general (i.e., ellipsoidal) Gauss...
We describe a new approach to speech recognition, in which all Hidden Markov Model (HMM) states share the same Gaussian Mixture Model (GMM) structure with the same number of Gaussians in each state. The model is defined by vectors associated with each state with a dimension of, say, 50, together with a global mapping from this vector space to the space of parameters of the GMM. This model appea...
background & aim: in the survival data with long-term survivors the event has not occurred for all the patients despite long-term follow-up, so the survival time for a certain percent is censored at the end of the study. mixture cure model was introduced by boag, 1949 for reaching a more efficient analysis of this set of data. because of some disadvantages of this model non-mixtur...
This paper proposes a continous space text model based on Gaussian processes. Introducing latent coordinates of words over which the Gaussian process is defined, we can encode word correlations directly and lead to a model that performs better than mixture models. Our model would serve as a foundation of more complex text models and also as a statistical visualization of texts.
speaker verification is the process of accepting or rejecting claimed identity in terms of its sound features. a speaker verification system can be used for numerous security systems, including bank account accessing, getting to security points, criminology and etc. when a speaker verification system wants to check the identity of individuals remotely, it confronts problems such as noise effect...
