Reason Before You Retrieve: Agentic Planning for Multi-modal RAG

Tianyu Yang, Shir Simon, Zhenzhen Li +2

Multimodal retrieval-augmented generation (mRAG) aims to answer image-text queries with external knowledge, but most existing systems still retrieve directly from raw multimodal in…

Scalable Token-Level Hallucination Detection in Large Language Models

Rui Min, Tianyu Pang, Chao Du +2

Large language models (LLMs) have demonstrated remarkable capabilities, but they still frequently produce hallucinations. These hallucinations are difficult to detect in reasoning-…

Route Before Retrieve: Activating Latent Routing Abilities of LLMs for RAG vs. Long-Context Selection

Yiwen Chen, Kuan Li, Fuzhen Zhuang +6

Recent advances in large language models (LLMs) have expanded the context window to beyond 128K tokens, enabling long-document understanding and multi-source reasoning. A key chall…

CARV: A Diagnostic Benchmark for Compositional Analogical Reasoning in Multimodal LLMs

Yongkang Du, Xiaohan Zou, Minhao Cheng +1

Analogical reasoning tests a fundamental aspect of human cognition: mapping the relation from one pair of objects to another. Existing evaluations of this ability in multimodal lar…

ReSum: Unlocking Long-Horizon Search Intelligence via Context Summarization

Xixi Wu, Kuan Li, Yida Zhao +13

Large Language Model (LLM)-based web agents excel at knowledge-intensive tasks but face a fundamental conflict between the need for extensive exploration and the constraints of lim…

LaRA: Benchmarking Retrieval-Augmented Generation and Long-Context LLMs -- No Silver Bullet for LC or RAG Routing

Kuan Li, Liwen Zhang, Yong Jiang +4

Effectively incorporating external knowledge into Large Language Models (LLMs) is crucial for enhancing their capabilities and addressing real-world needs. Retrieval-Augmented Gene…
