EM algorithms for multivariate Gaussian mixture models with truncated and censored data
نویسندگان
چکیده
We present expectation-maximization(EM) algorithms for fitting multivariate Gaussian mixture models to data that is truncated, censored or truncated and censored. These two types of incomplete measurements are naturally handled together through their relation to the multivariate truncated Gaussian distribution. We illustrate our algorithms on synthetic and flow cytometry data.

Face recognition system based on Doubly truncated multivariate Gaussian Mixture Model
A face recognition algorithm based on doubly truncated multivariate Gaussian mixture model with DCT is introduced. The truncation on the feature vector with a significant influence on improving the recognition rate of the system using EM algorithm with K-means or hierarchical clustering is implemented. The characteristic model parameters are estimated. The EM algorithm containing the updated eq...
متن کاملEM and Stochastic EM algorithms for reliability mixture models under random censoring
Mixture models in reliability bring a useful compromise between parametric and nonparametric models, when several failure modes are suspected. The classical methods for estimation in mixture models rarely handle the additional difficulty coming from the fact that lifetime data are often censored, in a deterministic or random way. We present in this paper several iterative methods based on EM an...
متن کاملThe Noisy Expectation-Maximization Algorithm
We present a noise-injected version of the Expectation-Maximization (EM) algorithm: the Noisy Expectation Maximization (NEM) algorithm. The NEM algorithm uses noise to speed up the convergence of the EM algorithm. The NEM theorem shows that additive noise speeds up the average convergence of the EM algorithm to a local maximum of the likelihood surface if a positivity condition holds. Corollary...
متن کاملBayesian Analysis of Censored Spatial Data Based on a Non-Gaussian Model
Abstract: In this paper, we suggest using a skew Gaussian-log Gaussian model for the analysis of spatial censored data from a Bayesian point of view. This approach furnishes an extension of the skew log Gaussian model to accommodate to both skewness and heavy tails and also censored data. All of the characteristics mentioned are three pervasive features of spatial data. We utilize data augme...
متن کاملImage Segmentation using Gaussian Mixture Model
Abstract: Stochastic models such as mixture models, graphical models, Markov random fields and hidden Markov models have key role in probabilistic data analysis. In this paper, we used Gaussian mixture model to the pixels of an image. The parameters of the model were estimated by EM-algorithm. In addition pixel labeling corresponded to each pixel of true image was made by Bayes rule. In fact,...
