Gaussian mixture modeling is a powerful approach for data analysis and the determination of the number of Gaussians, or clusters, is actually the problem of Gaussian mixture model selection which has been investigated from several respects. This paper proposes a new kind of automated model selection...

Gaussian mixture models(GMMs) assign each observation to a cluster by maximizing the posterior probability that a data point belongs to its assigned cluster. Create a GMM objectgmdistributionby fitting a model to data (fitgmdist) or by specifying parameter values (gmdistribution). Then, use object...
A Gaussian mixture model (GMM) is a probabilistic model that assumes that the data it is modeling is generated by a mixture of multiple Gaussian distributions. This means that each data point is assumed to come from one of the Gaussian distributions, and the probability of a data point ...

posture recognitionGMMIn this paper, we proposed an unsupervised posture modeling method based on Gaussian Mixture Model (GMM). Specifically, each learning posture is described based on its movement features by a set of spatial-temporal interest points (STIPs), salient postures are then clustered ...
