Researchers have introduced a new diagnostic tool called "answer-in-context" to better evaluate retrieval-augmented generation (RAG) systems. This diagnostic measures whether a correct answer remains intact within the limited context window provided to the RAG model, proving more effective than traditional recall metrics. Additionally, the study proposes a method for constructing reader contexts by framing it as a budgeted submodular maximization problem, which optimizes for relevance, coverage, and diversity. This approach shows improvements on specific datasets and under certain conditions, particularly when dealing with multi-hop reasoning and smaller language models. AI
