Question 118

View question permalink page

During retrieval quality evaluation, an engineer runs the same set of test queries through the pipeline twice — once with the reranker disabled and once with it enabled — and compares DCG@10 scores for each query type. For one query type, enabling the reranker raises DCG@10 significantly with only a modest latency increase; for another query type, it makes almost no difference. What is the most appropriate way to use this evaluation result?
