Abstract

A machine learning device includes a state variable acquiring section, a teaching data acquiring section, and a learned model generating section. The state variable acquiring section acquires, as state variables: feature information that is information regarding a feature of an actual printed matter on which printing has been actually performed by an image forming apparatus; medium information that is information regarding a print medium used in the actual printed matter; and first control information that is information regarding control performed when the actual printed matter has been outputted. The teaching data acquiring section acquires, as teaching data, second control information that is information regarding control that causes the feature information to fall within a predetermined threshold. The learned model generating section generates a learned model by performing machine learning on the basis of the pieces of information acquired by the state variable acquiring section and the teaching data.
