Claim 0:
1. An output device comprising:
an information acquisition unit which acquires, from a machine learning device that performs 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,
(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) an evaluation function value; and

an output unit which outputs 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 output unit includes a display unit which displays, 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 output unit determines whether or not an order of the coefficient has been changed by a user, and
when the output unit determines that the order of the coefficient has been changed by the user, the output unit outputs, to the servo control device, a correction instruction including a change of an order of the coefficient.
