CONCORD: Asynchronous Sparse Aggregation Boosts Device-Cloud RAG Efficiency Under Document Isolation
A new framework called CONCORD addresses the challenge of document isolation in device-cloud retrieval-augmented generation (RAG). By treating the cloud as an asynchronous evidence source and introducing waiting debt control and certificate-guided minimal supplementation, CONCORD improves end-to-end throughput by 1.66× to 2.15× over baselines while cutting per-token communication by over two orders of magnitude. Experiments on Natural Questions and WikiText-2 demonstrate comparable answer quality and perplexity.
MAGE-RAG: Multigranular Adaptive Graph Evidence Framework Improves Long-Document Multimodal QA Accuracy
The MAGE-RAG research paper introduces a multigranular adaptive graph evidence framework for multimodal retrieval-augmented generation (RAG) in long-document question answering. By building an evidence graph with page and element nodes and using an online controller to iteratively activate and prune evidence, it balances coverage and noise. Experiments show accuracy improvements over existing methods on LongDocURL and MMLongBench-Doc benchmarks.
