摘要：A model estimation device 100 includes a hidden variable variational probabilitycalculation processing unit 104 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 105 for optimizing the parameters of thehidden variable model by use of the constrained hidden variable variational probability,and an optimality determination processing unit 106 for determining whether amarginalized log likelihood function using the optimized parameters is converged,wherein when it is determined that the marginalized log likelihood function is converged,the constrained hidden variable variational probability and the parameters used for themarginalized log likelihood function are output.
