Retrieval Helps or Hurts? A Deeper Dive into the Efficacy of Retrieval Augmentation to Language Models

1 code implementation • 21 Feb 2024 • Seiji Maekawa, Hayate Iso, Sairam Gurajada, Nikita Bhutani

We demonstrate the efficacy of our finer-grained metric and insights through an adaptive retrieval system that selectively employs retrieval and recall based on the frequencies of entities and relations in the question.
