Computer-readable recording medium recording estimation program, estimation method, and information processing device

An estimation method comprising:

• calculating, by a computer, a reconfiguration error from an input result value and a reconfiguration value that is estimated by a first estimator, which estimates a parameter value from a result value learned on a basis of past data, and a second estimator, which estimates a result value from a parameter value, by using a specific result value or a neighborhood result value in a neighborhood of the specific result value;
• searching for a first result value that minimizes a sum of a substitute error that is calculated from the input result value and the specific result value and the reconfiguration error;
• and
• outputting a parameter value that is estimated from the first result value by using the first estimator.

An information processing device comprising:

• a memory;
• and
• a processor coupled to the memory and configured to:
• calculate a reconfiguration error from an input result value and a reconfiguration value that is estimated by a first estimator, which estimates a parameter value from a result value learned on a basis of past data, and a second estimator, which estimates a result value from a parameter value, by using a specific result value or a neighborhood result value in a neighborhood of the specific result value;
• search for a first result value that minimizes a sum of a substitute error that is calculated from the input result value and the specific result value and the reconfiguration error;
• and
• output a parameter value that is estimated from the first result value by using the first estimator.
