A Survey of Graph Retrieval-Augmented Generation for Customized Large Language Models

1 code implementation21 Jan 2025 Qinggang Zhang, Shengyuan Chen, Yuanchen Bei, Zheng Yuan, Huachi Zhou, Zijin Hong, Junnan Dong, Hao Chen, Yi Chang, Xiao Huang

Large language models (LLMs) have demonstrated remarkable capabilities in a wide range of tasks, yet their application to specialized domains remains challenging due to the need for deep expertise.

Each Graph is a New Language: Graph Learning with LLMs

no code implementations20 Jan 2025 Huachi Zhou, Jiahe Du, Chuang Zhou, Chang Yang, Yilin Xiao, Yuxuan Xie, Xiao Huang

By treating graphs as a new language, GDL4LLM enables LLMs to model graph structures adequately and concisely for node classification tasks.

Modality-Aware Integration with Large Language Models for Knowledge-based Visual Question Answering

no code implementations20 Feb 2024 Junnan Dong, Qinggang Zhang, Huachi Zhou, Daochen Zha, Pai Zheng, Xiao Huang

Specifically, (i) we propose a two-stage prompting strategy with LLMs to densely embody the image into a scene graph with detailed visual features; (ii) We construct a coupled concept graph by linking the mentioned entities with external facts.

Could Small Language Models Serve as Recommenders? Towards Data-centric Cold-start Recommendations

1 code implementation29 Jun 2023 Xuansheng Wu, Huachi Zhou, Yucheng Shi, Wenlin Yao, Xiao Huang, Ninghao Liu

To evaluate our approach, we introduce a cold-start recommendation benchmark, and the results demonstrate that the enhanced small language models can achieve comparable cold-start recommendation performance to that of large models with only $17\%$ of the inference time.

Improving Generalizability of Graph Anomaly Detection Models via Data Augmentation

1 code implementation18 Jun 2023 Shuang Zhou, Xiao Huang, Ninghao Liu, Huachi Zhou, Fu-Lai Chung, Long-Kai Huang

In this paper, we base on the phenomenon and propose a general and novel research problem of generalized graph anomaly detection that aims to effectively identify anomalies on both the training-domain graph and unseen testing graph to eliminate potential dangers.
