Learning method and device, program, learned model, and text generation device

Abstract

Provided are a learning method and device of a model used for processing of automatically generating a text from an image, a program, a learned model, and a text generation device. In a learning method according to an embodiment of the present disclosure, a learning model including a feature amount extraction unit that extracts an image feature amount from an image, a text generation unit that generates an estimated text from the image feature amount, and a statistic estimation unit that generates an estimated image statistic from the text is used, and a combination of a first image, first metadata, and a first text is used as learning data. A first error of a first estimated text estimated from a first image feature amount of the first image, a second error of a first estimated image statistic estimated from the first text, and a third error of a second estimated image statistic estimated from the first estimated text are calculated, and a parameter of the learning model is updated.
