摘要：A model estimation device includes: a data input unit ; a state number settingunit; an initialization unit; a latent variable variational probability computation unit whichcomputes a variational probability of a latent variable so as to maximize a lower bound of

a model posterior probability limited in degree of freedom; a component optimizationunit which estimates an optimal type of each component and a parameter thereof so asto maximize the lower bound of the model posterior probability limited in degree offreedom and separated for each component of a latent variable model; a free parameterselection variable computation unit which computes the free parameter selectionvariable; an optimality determination unit which determines whether or not to continuethe maximization of the lower bound of the model posterior probability; and a resultoutput unit.
