For example, for the case of mixture models, posterior density for each component parameters would be a BayesianModel from Exponential Family. 137 142 138 This class uses EM-style type algorithms for estimation of its parameters. Under this simplification, the posterior density is a product of exponential family members, hence approximate estimation projectthis class itself belongs to the exponential family.143 This class uses EM-style type algorithms for estimation of its parameters.
