UnverifiedNeither Recall@k nor Reciprocal Rank@k measures whether the final answer is correct, safe, or grounded; both only answer questions at the retrieval level.68% similarUnverifiedThe pragmatic approach is to first evaluate retrieval quality independently before connecting the generation stage: if the Top-K retrieved content does not contain the answer, switching to a stronger model cannot remedy the situation.66% similarUnverifiedRecovering the correct variable ordering does not require the estimation errors of the ordering scores to be uniformly small everywhere, but only requires one-sided control of these errors.64% similarUnverifiedThe solution to the ordering problem is: when a slide ID list exists, parse the order by it first; when it does not exist, fall back to document order; when the two disagree, log a warning.64% similarVerifiedReranking technology first uses coarse retrieval to recall a large number of candidate segments, then uses a fine-ranking model to re-score them, keeping only the most relevant content to feed into the model.63% similar
