Claim 6:
7. A method of outputting an evaluation function value of an output device which is used in machine learning of a machine learning device that performs the machine learning on a servo control device for controlling a servo motor driving an axis of a machine tool, a robot or an industrial machine, the method comprising:
acquiring, from the machine learning device,
(i) a parameter of a constituent element of the servo control device that is being machine learned or has been machine learned, or a first physical quantity of the constituent element of the servo control device that is being machine learned or has been machine learned, and
(ii) the evaluation function value; and
outputting information indicating a relationship between (i) the evaluation function value and (ii) the parameter, the first physical quantity, or a second physical quantity determined from the parameter,
wherein the outputting comprises displaying, on a display screen, a diagram which depicts the relationship between (i) the evaluation function value and (ii) the parameter, the first physical quantity, or the second physical quantity,
the parameter is a coefficient in a transfer function of the constituent element of the servo control device,
the outputting further comprises determining whether or not an order of the coefficient has been changed by a user, and
when it is determined that the order of the coefficient has been changed by the user, the outputting further comprises outputting, to the servo control device, a correction instruction including a change of an order of the coefficient.
