G-reasoner: Foundation Models for Unified Reasoning over Graph-structured Knowledge

Linhao Luo, Zicheng Zhao, Junnan Liu +9

Large language models (LLMs) excel at complex reasoning but remain limited by static and incomplete parametric knowledge. Retrieval-augmented generation (RAG) mitigates this by inc…

Beyond Memorization: A Rigorous Evaluation Framework for Medical Knowledge Editing

Shigeng Chen, Linhao Luo, Zhangchi Qiu +3

Recently, knowledge editing (KE) has emerged as a promising approach to update specific facts in Large Language Models (LLMs) without the need for full retraining. Despite the effe…

GFM-RAG: Graph Foundation Model for Retrieval Augmented Generation

Linhao Luo, Zicheng Zhao, Gholamreza Haffari +3

Retrieval-augmented generation (RAG) has proven effective in integrating knowledge into large language models (LLMs). However, conventional RAGs struggle to capture complex relatio…

Graph-constrained Reasoning: Faithful Reasoning on Knowledge Graphs with Large Language Models

Linhao Luo, Zicheng Zhao, Gholamreza Haffari +3

Large language models (LLMs) have demonstrated impressive reasoning abilities, but they still struggle with faithful reasoning due to knowledge gaps and hallucinations. To address…
