Hurdle models differ from zero-inflated models in that zero-inflated models model the zeros using a two-component mixture model. With a mixture model, the...

Subspace Gaussian mixture model (SGMM) is an acoustic modeling approach in which all phonetic states share a common Gaussian mixture model structure, and...

In chemistry, a mixture is a material made up of two or more different chemical substances which can be separated by physical method. It is an impure...

feature is the relation between the viscosity model for a pure fluid and the model for a fluid mixture which is called mixing rules. When scientists and...

that of a mixture model, in which the task is to infer from which of a discrete set of sub-populations each observation originated. Mixture distribution...

conditions. In econometric models, the parameters may be bimodally distributed. A bimodal distribution commonly arises as a mixture of two different unimodal...

Dirichlet processes is as a prior probability distribution in infinite mixture models. The Dirichlet process was formally introduced by Thomas S. Ferguson...

For example, a typical Gaussian mixture model will have parameters for the mean and variance of each of the mixture components. EM would directly estimate...

indicate 'correct trial' versus 'measurement error'; this is modeled by a mixture model. In most larger samplings of data, some data points will be further...

distributions: one for background modelling and another for foreground pixels. Use a Gaussian mixture model (with 5–8 components) to model those 2 distributions....

resulting model above is called a HDP mixture model, with the HDP referring to the hierarchically linked set of Dirichlet processes, and the mixture model referring...
