Retrieval-Augmented Generation for Knowledge-Intensive NLP Tasks

Lewis, Perez, Piktus, Petroni et al. · NeurIPS · 2020

Abstract

Combines a parametric language model with a non-parametric retriever over a document index, letting the model ground its answers in fetched passages rather than memorized weights.

Why it matters

The origin of "RAG". Explains why bolting a retriever onto a model beats fine-tuning for fast-changing knowledge — the pattern behind most production AI search today.
