Large language models (LLMs) have demonstrated remarkable performance across various real-world tasks. However, they often struggle to fully comprehend and effectively utilize their input contexts, resulting in responses that are unfaithful or hallucinated. This difficulty increases for contexts long contain distracting information, which can divert LLMs from capturing essential evidence. To address this issue, many works use prompting help contextual information more faithfully. For...
