recurrent memory transformer pytorch
0.7.0
Implementierung von Recurrent Memory Transformer (openreview) in Pytorch. Kürzlich gab es ein kurzes Follow-up-Papier, das zeigte, dass es in der Lage war, Informationen über mindestens 1 Million Token zu kopieren.
Ich habe keinen Zweifel daran, dass RMT ein stärkerer RL-Agent wäre als AdA, das nur ein Transformer-XL ist – Update: Recurrent Action Transformer with Memory (RATE)

Sorgen Sie dafür, dass rotierende Einbettungen mit XL-Speichern ordnungsgemäß funktionieren
Fügen Sie XL-Erinnerungen hinzu, losgelöst
bieten eine Möglichkeit, rotierende Einbettungen und absolute Positionseinbettungen zu deaktivieren und eine Token-Verschiebung hinzuzufügen
Machen Sie Erinnerungen, die kausal maskiert werden, zu einer Option
Fügen Sie die Memory-Replay-Backprop-Technik aus Memformer-Papier hinzu
relative Positionskodierung
Blockieren Sie wiederkehrende Transformatoren
