Learning device and learning program and sentence generator and sentence generator

摘要

PROBLEM TO BE SOLVED: To prevent an output sentence from becoming a general-purpose expression when an output sentence related to the content of the input sentence and different from the input sentence is generated from the input sentence. A learning device uses a generation model that generates an output sentence that is related to the content of the input sentence and is different from the input sentence from the input sentence, and generates an output sentence from the input sentence, and an output sentence. Using the restoration model that restores the input statement from, the generation model and the restoration model are trained using the error between the restoration unit 32 that restores the input statement from the output statement and the restoration statement that is restored by the input statement and the restoration unit. A second update unit 36, which updates the generation model and the restoration model, is provided. [Selection diagram] Fig. 2
