Generative Dense Retrieval: Memory Can Be a Burden
The paper introduces Generative Dense Retrieval (GDR), a two‑stage retrieval framework that first maps queries to memory‑efficient document‑cluster identifiers and then uses dense vectors to locate individual documents, achieving higher recall and better scalability than traditional generative retrieval while incurring modest latency and capacity trade‑offs.
