Abstract: This method for creating a machine learning model for outputting a feature map involves receiving a plurality of learning images, using an initial machine learning model to sort the plurality of learning images into respective initial clusters from among a plurality of initial clusters, resorting the plurality of initial clusters into a plurality of secondary clusters on the basis of the plurality of learning images as sorted into each of the plurality of initial clusters, and creating a m machine learning model by making the initial machine learning model learn the relationship between the plurality of initial clusters and the plurality of secondary clusters, the machine learning model being for sorting single inputted images into single secondary clusters from among the plurality of secondary clusters.
