Classification: CPC G | IPC G

Claim 4:
5. A non-transitory computer readable recording medium storing an operation program of a mini-batch learning apparatus that learns a machine learning model for performing semantic segmentation, which determines a plurality of classes in an image in units of pixels, by inputting mini-batch data to the machine learning model, the program causing a computer to function as:
a calculation unit that calculates an area ratio of each of the plurality of classes in the mini-batch data;
a specifying unit that specifies a rare class of which the area ratio is lower than a setting value; and
an update unit that updates the machine learning model according to a result of the learning using the mini-batch data and sets an update level of the machine learning model in a case where the rare class is specified by the specifying unit to be lower than an update level of the machine learning model in a case where the rare class is not specified by the specifying unit.
