Моделирование языка и двунаправленные представления кодировщиков: обзор ключевых технологий
https://doi.org/10.37661/1816-0301-2020-17-4-61-72
Аннотация
Представлен очерк развития технологий обработки естественного языка, которые легли в основу BERT (Bidirectional Encoder Representations from Transformers) − языковой модели от компании Google, демонстрирующей высокие результаты на целом классе задач, связанных с пониманием естественного языка. Две ключевые идеи, реализованные в BERT, – это перенос знаний и механизм внимания. Модель предобучена решению нескольких задач на обширном корпусе неразмеченных данных и может применять обнаруженные языковые закономерности для эффективного дообучения под конкретную проблему обработки текста. Использованная архитектура Transformer основана на внимании, т. е. предполагает оценку взаимосвязей между токенами входных данных. В статье отмечены сильные и слабые стороны BERT и направления дальнейшего усовершенствования модели.
