ADAPTIVE LEARNING DEVICE OF DATA POSITIONAL RELATIONSHIP, ADAPTIVE LEARNING METHOD OF DATA POSITIONAL RELATIONSHIP, AND RECORDING MEDIUM STORING ADAPTIVE LEARNING PROGRAM OF DATA POSITIONAL RELATIONSHIP

摘要

An adaptive learning device of data positional relationship includes: an arithmetic unit that calculates a parameter of a model having a mapping function of plotting a plurality of pieces of data in a Euclidean space, the parameter minimizing a triplet loss function to which a value of the model is input when a triplet set is given to the model; a determination unit that determines whether a group made up of the model having the parameter being calculated and the triplet set satisfies a predetermined conditional expression; and a first generation unit that generates a new triplet set to be targeted for an arithmetic operation by the arithmetic unit, by removing at least one triplet from the triplet set of the group determined not to satisfy the predetermined conditional expression, thereby enabling learning of the positional relationship between the pieces of data when any data set is given.
