Evidencepartial
current reranking models are typically optimized on static human annotated relevance labels in isolation, decoupled from the downstream generation process
Implicationpartial
Directly stated in abstract with clear description of current methodology
Verificationpartial
partial
Evidencepartial
documents identified as topically relevant by information retrieval metrics often fail to provide the actual utility required by the LLM for precise answer generation
Implicationpartial
Directly stated in abstract as a fundamental problem with current approaches
Verificationpartial
partial
Evidencepartial
we introduce ReRanking Preference Optimization (RRPO), a reinforcement learning framework that directly aligns reranking with the LLM's generation quality
Implicationpartial
