Model identification system, method of operation of the model identification program and model identification equipment

摘要

PPROBLEM TO BE SOLVED: To specify model parameters while using a mathematical model that represents the characteristics of a model object, in such a way as to make effective use of a large amount of performance data to increase the predictive accuracy of the mathematical model. PSOLUTION: Among classification patterns that classify the performance data into two groups, the classification pattern that makes bigger the difference in statistical information about the predictive errors of the mathematical model between the two groups is determined (S3). A processing (S4) for identifying the mathematical model for each group with the determined classification pattern is repeated as the groups are subdivided until the predictive accuracy for the model meets preset requirements (S6, S8). Parameters when the preset requirements are met are set as parameters for the mathematical model of that group. Determination of the classification pattern proceeds by first selecting data items for use in grouping based on average values and standard deviations, and determining from among them the classification pattern that is to be employed according to information standards (S3).
