Generation apparatus, generation method, and recording medium

A generation method, which is executed by a generation apparatus,

• the generation apparatus including a processor configured to execute a program, and a storage device configured to store the program,
• the generation apparatus being configured to access a set of pieces of learning data each being a combination of a value of an explanatory variable and a value of an objective variable, a function family list including, of functions each indicating a physical law and an attribute of each of the functions, at least the functions, and search range limiting information for limiting a search range of the function family list,
• the generation method comprising executing, by the processor:
• first generation processing of generating a first prediction expression by setting a first parameter for the explanatory variable to a first function included in the function family list;
• first calculation processing of calculating, based on the search range limiting information, a first conviction degree relating to the first prediction expression generated through the first generation processing;
• and
• first output processing of outputting the first prediction expression and the first conviction degree calculated through the first calculation processing.

A computer-readable non-transitory recording medium having recorded thereon a generation program for causing a processor to generate a rule for predicting data,

• the processor being configured to access a set of pieces of learning data each being a combination of a value of an explanatory variable and a value of an objective variable, a function family list including, of functions each indicating a physical law and an attribute of each of the functions, at least the functions, and search range limiting information for limiting a search range of the function family list,
• the generation program causing the processor to execute:
• first generation processing of generating a first prediction expression by setting a first parameter for the explanatory variable to a first function included in the function family list;
• first calculation processing of calculating, based on the search range limiting information, a first conviction degree relating to the first prediction expression generated through the first generation processing;
• and
• first output processing of outputting the first prediction expression and the first conviction degree calculated through the first calculation processing.
