A learning management device comprising an inference engine that is input with image data and acquires output for performing guidance display to a user using an inference model that has been specifically learned, and a processor that confirms if there is a specified relationship between a trial input image and trial guidance display for this trial input image under conditions that have been assumed at the time of use, and that determines whether or not it is necessary to relearn the inference model that has been learned based on the result of this confirmation.
