Beyond the Golden Teacher: Enhancing Graph Learning through LLM-GNN Co-teaching

Zhuoyi Peng, Hanlin Gu, Lixin Fan +1

Text-attributed graphs (TAGs) underlie real-world applications such as citation networks, social media, and e-commerce. Few-shot graph learning on TAGs is hard: with only a handful…

GraphInfer-Bench: Benchmarking LLM's Inference Capability on Graphs

Zhuoyi Peng, Jingzhou Jiang, Hanlin Gu +2

Graph analysis underlies many applications whose answers cannot be looked up in a single record or retrieved along a path: laundering rings, drug repurposing, user preference, and…

Federated Co-tuning Framework for Large and Small Language Models

Tao Fan, Yan Kang, Guoqiang Ma +4

By adapting Large Language Models (LLMs) to domain-specific tasks or enriching them with domain-specific knowledge, we can fully harness the capabilities of LLMs. Nonetheless, a ga…

Towards Privacy-Guaranteed Label Unlearning in Vertical Federated Learning: Few-Shot Forgetting without Disclosure

Hanlin Gu, Hong Xi Tae, Lixin Fan +1

This paper addresses the critical challenge of unlearning in Vertical Federated Learning (VFL), a setting that has received far less attention than its horizontal counterpart. Spec…
