arXiv:2505.16014v5 Announce Type: replace Abstract: Retrieval-Augmented Generation (RAG) systems deployed in sensitive domains must provide interpretable evidence selection and robust safeguards against data poisoning, yet current approaches rely on opaque similarity-based retrieval with arbitrary top-k cutoffs that offer no explanation for their selections and remain vulnerable to adversarial manipulation. METEORA replaces re-ranking with rationale-driven selection via three components: a DPO-tuned LLM that generates explicit retrieval rationales, an Evidence Chunk Selection Engine (ECSE) tha
The increasing deployment of RAG systems in sensitive and mission-critical applications necessitates more robust, interpretable, and secure methods for evidence selection to counter inherent vulnerabilities.
This development addresses critical challenges in AI safety, interpretability, and reliability, essential for broader adoption of RAG in high-stakes environments, particularly national security, finance and healthcare.
Traditional opaque similarity-based retrieval in RAG is replaced by a rationale-driven selection process, offering greater transparency, accountability, and resilience against adversarial manipulation.

Increased trust and adoption of RAG in highly regulated and sensitive industries.
Demand for AI models capable of generating explicit and verifiable rationales will accelerate, shifting research priorities.
New regulatory frameworks for AI will likely incorporate requirements for rationale-driven evidence selection and demonstrable safeguards.
