<P>PROBLEM TO BE SOLVED: To provide a model parameter estimation device that performs state estimation at a high speed and with high accuracy by the sequential Monte Carlo method. <P>SOLUTION: A model parameter estimation device 1 comprises: hypothesis storage means 20 that stores plural pieces of hypothesis data to be candidates of the solution of a parameter; plural pieces of hypothesis processing means 30 (30<SB POS="POST">1</SB>, 30<SB POS="POST">2</SB>, ..., 30<SB POS="POST">N</SB>) that sample hypothesis data based on a proposal distribution in the sequential Monte Carlo method that is a predetermined distribution of the parameter, and update the hypothesis data stored in the hypothesis storage means 20; and control means 10 that distributes the plural pieces of hypothesis data stored in the hypothesis storage means 20 to the plural pieces of hypothesis processing means 30, and parallelly operates the plural pieces of hypothesis processing means 30. <P>COPYRIGHT: (C)2012,JPO&INPIT |
