摘要：A model estimation device includes a hidden variable variational probability

calculation processing unit for acquiring parameters of a hidden variable model andcalculating a constrained hidden variable variational probability as a hidden variableposterior probability close to a previously-given distribution by use of the parameters, amodel parameter optimization processing unit for optimizing the parameters of thehidden variable model by use of the constrained hidden variable variational probability,and an optimality determination processing unit for determining whether a marginalizedlog likelihood function using the optimized parameters is converged, wherein when it isdetermined that the marginalized log likelihood function is converged, the constrainedhidden variable variational probability and the parameters used for the marginalized loglikelihood function are output.
