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.
APEX Adaptive Principle Extraction Framework Enables Multi-Dimensional Self-Evolution for Production AI Agents
Researchers propose APEX (Adaptive Principle EXtraction), a three-layer self-evolution framework that simultaneously improves an AI agent's prompt harness, behavioural principles, and workflow topology. Tested on the production-grade Joe AI agent built on NVIDIA Nemotron, APEX achieved a 90% improvement in Health Score over baseline, distilling six novel reusable principles and selecting a research-first workflow scoring 0.900 (+20%). The framework outperforms single-axis harness optimisation and requires only 4 LLM calls (~270 seconds).
