JointCoder addresses these issues with two contributions. 2. **[D²-RAG: Dual-Decision Retrieval-Augmented Generation via Multi-Dimensional Uncertainty and Utility-Aware Decoding](https://md.research.elamur.ai/free/en/papers/zhang-2026-d-2-rag-dual-decision/)** *(2026)* Retrieval-augmented generation (RAG) can reduce hallucinations, but it has two weaknesses. It often retrieves when the model already knows the answer, and it treats every retrieved passage as equally useful, so noisy passages can mislead the model.
