recurrent memory transformer pytorch
0.7.0
Implémentation de Recurrent Memory Transformer (openreview) dans Pytorch. Ils ont récemment publié un court document de suivi démontrant qu'il était capable de copier des informations sur au moins 1 million de jetons.
Il ne fait aucun doute dans mon esprit que RMT ferait un agent RL plus puissant qu'AdA, qui n'est qu'un Transformer-XL - Mise à jour : Transformateur d'action récurrente avec mémoire (RATE)

faire fonctionner correctement les intégrations rotatives avec les mémoires XL
ajouter des souvenirs xl, détachés
offrir un moyen de désactiver les intégrations rotatives, les intégrations positionnelles absolues et d'ajouter un décalage de jeton
faire des souvenirs masqués causalement une option
ajouter la technique de backprop de relecture de mémoire à partir du papier memformer
codage de position relative
