Turn-PPO: Turn-Level Advantage Estimation with PPO for Improved Multi-Turn RL in Agentic LLMs

Junbo Li, Peng Zhou, Rui Meng +3

Reinforcement learning (RL) has re-emerged as a natural approach for training interactive LLM agents in real-world environments. However, directly applying the widely used Group Re…

Retrieval--Reasoning Processes for Multi-hop Question Answering: A Four-Axis Design Framework and Empirical Trends

Yuelyu Ji, Zhuochun Li, Rui Meng +1

Multi-hop question answering (QA) requires systems to iteratively retrieve evidence and reason across multiple hops. While recent RAG and agentic methods report strong results, the…

Curriculum Guided Reinforcement Learning for Efficient Multi Hop Retrieval Augmented Generation

Yuelyu Ji, Rui Meng, Zhuochun Li +1

Retrieval-augmented generation (RAG) grounds large language models (LLMs) in up-to-date external evidence, yet existing multi-hop RAG pipelines still issue redundant subqueries, ex…

Memory-Aware and Uncertainty-Guided Retrieval for Multi-Hop Question Answering

Yuelyu Ji, Rui Meng, Zhuochun Li +1

Multi-hop question answering (QA) requires models to retrieve and reason over multiple pieces of evidence. While Retrieval-Augmented Generation (RAG) has made progress in this area…
