  • Publication number: 20240394329
    Abstract: An acquisition section (101) acquires an actual measurement value of a measured change in a specific environment of a data assimilation target. A computation section (102) uses a preliminary initial state and a preliminary value of an unknown parameter that are related to the data assimilation target to perform a numerical computation of a change in the specific environment of the data assimilation target. An update section (103) computes a value of an evaluation function representing errors between the actual measurement value and a value obtained from a result of the numerical computation and corresponding to the actual measurement value, finds an acquisition function from plural combinations of values of the initial state and the unknown parameter combined with the evaluation function value, and updates values of the initial state and the unknown parameter so as to minimize a value of the evaluation function based on a value of the acquisition function.
