LEARNING METHOD, CLUSTERING METHOD, LEARNING DEVICE, CLUSTERING DEVICE, AND PROGRAM

摘要

In the learning device according to an embodiment, a computer executes: an input procedure for inputting a plurality of items of data and a plurality of labels respectively representing a cluster to which the data belongs; an expression generation procedure for converting each of the plurality of items of data by means of a prescribed neural network and generating a plurality of items of expression data; a clustering procedure for clustering the plurality of items of expression data; a calculation procedure for calculating, on the basis of the result of the clustering and the plurality of labels, a prescribed evaluation scale representing the performance of the clustering; and a learning procedure for learning parameters of the neural network on the basis of the evaluation scale.
