Реализация преобразователя рекуррентной памяти (открытый обзор) в Pytorch. Недавно у них была короткая дополнительная статья, которая продемонстрировала, что она способна копировать информацию как минимум на 1 миллион токенов.
Я не сомневаюсь, что RMT станет более сильным агентом RL, чем AdA, который представляет собой всего лишь Transformer-XL — Обновление: Трансформатор повторяющегося действия с памятью (RATE).

переместите обратную связь воспроизведения памяти в функцию torch.function, проверьте двунаправленность, затем протестируйте реальную проблему
заставить вращающиеся вложения работать правильно с памятью xl
добавить воспоминания xl, отдельные
предложить способ отключить поворотные вложения, абсолютные позиционные вложения и добавить сдвиг токенов
сделать так, чтобы воспоминания были причинно замаскированы
добавить технику обратного воспроизведения воспроизведения памяти из бумаги memformer
относительное позиционное кодирование
