This makes inference expensive, and long contexts can distract the model with irrelevant or badly placed information. RECOMP (Retrieve, Compress, Prepend) adds a small trainable step between retrieval and a frozen, black-box LM: the… 2. **[A Critical Evaluation of Evaluations for Long-form Question Answering](https://md.research.elamur.ai/free/en/papers/xu-2023-critical-evaluation-evaluations-long-form/)** *(2023 · 112 citations)* Evaluating long-form question answering (LFQA) is hard because answers are open-ended.
