A new paper from Hugging Face investigates the effectiveness of retrieval-augmented generation (RAG) in question-answering systems. The research reveals that the presence of the correct answer within rewritten contexts significantly boosts performance, with its removal causing substantial drops in F1 scores. Conversely, injecting the gold answer into contexts where it was absent led to performance improvements across most tested configurations. AI
IMPACT This research suggests that RAG system improvements may be more about answer injection than complex rewriting, potentially simplifying future QA model development.
