When and Why Does Multi-Agent Debate Fail and Does It Really Underperform?

Yongqiang Chen, Gang Niu, James Cheng +2

Multi-agent debate (MAD) was proposed as a promising approach for ensembling the wisdom of multiple large language models (LLMs) to improve reasoning and provide effective supervis…

Reducing Belief Deviation in Reinforcement Learning for Active Reasoning

Deyu Zou, Yongqiang Chen, Jianxiang Wang +5

Active reasoning requires large language model (LLM) agents to interact with external sources and strategically gather information to solve problems in multiple turns. Central to t…

Weak-to-Strong GraphRAG: Aligning Weak Retrievers with Large Language Models for Graph-based Retrieval Augmented Generation

Deyu Zou, Yongqiang Chen, Mufei Li +5

Graph-based retrieval-augmented generation (RAG) enables large language models (LLMs) to ground responses with structured external knowledge from up-to-date knowledge graphs (KGs)…

DivIL: Unveiling and Addressing Over-Invariance for Out-of- Distribution Generalization

Jiaqi Wang, Yuhang Zhou, Zhixiong Zhang +3

Out-of-distribution generalization is a common problem that expects the model to perform well in the different distributions even far from the train data. A popular approach to add…
