摘要
On the basis of time-series data, a term-specific time-series data creation unit creates time-series data for each term that includes a derivative term; a linear sum generation unit generates, for each time point in the created time-series data, a raw value for the linear sum of the products of each term times a coefficient; a coefficient determination unit determines a coefficient for each term such that the total value of raw values for linear sums within the time interval or space interval covered by the time-series data is no greater than a set value, or approaches zero; and a governing equation output unit outputs, as a governing equation for the time-series data, the linear sum of the products of each coefficient determined by the coefficient determination unit times each term.
