The BIC criterion can be used to select the number of components in a Gaussian Mixture in an efficient way. In theory, it recovers the true number of components only in the asymptotic regime (i.e. if much data is available and assuming that the data was actually generated i.i.d. from a mixture of Gaussian … See more The main difficulty in learning Gaussian mixture models from unlabeled data is that it is one usually doesnt know which points came from which … See more The next figure compares the results obtained for the different type of the weight concentration prior (parameter weight_concentration_prior_type) … See more The parameters implementation of the BayesianGaussianMixture class proposes two types of prior for the weights distribution: a finite … See more The examples below compare Gaussian mixture models with a fixed number of components, to the variational Gaussian mixture models with a Dirichlet process prior.
