Learning apparatus, method and program, and information processing apparatus, method and program

Abstract

To provide a learning device, a method and a program, as well as an information processing method and a program that can accurately associate an image with a sentence.SOLUTION: In a medical information system, a learning device 7 comprises: a first derivation unit 22 that derives a first feature value for an object included in an image via a first neural network; a structured information derivation unit 23 that derives structured information for a sentence by structuring a sentence including description related to the object included in the image; and a second derivation unit 24 that derives a second feature value for a sentence from the structured information via a second neural network. When the object included in the image corresponds to the object described in the sentence, learning of the first neural network and the second neural network is done such that a distance between the first feature value and the second feature value derived is small in a feature space to which the first feature value and the second feature value belong.SELECTED DRAWING: Figure 4
