GOFA: A Generative One-For-All Model for Joint Graph Language Modeling

1 code implementation12 Jul 2024 Lecheng Kong, Jiarui Feng, Hao liu, Chengsong Huang, Jiaxin Huang, Yixin Chen, Muhan Zhang

For example, current attempts at designing general graph models either transform graph data into a language format for LLM-based prediction or still train a GNN model with LLM as an assistant.

TAGLAS: An atlas of text-attributed graph datasets in the era of large graph and language models

1 code implementation20 Jun 2024 Jiarui Feng, Hao liu, Lecheng Kong, Mingfang Zhu, Yixin Chen, Muhan Zhang

In TAGLAS, we collect and integrate more than 23 TAG datasets with domains ranging from citation graphs to molecule graphs and tasks from node classification to graph question-answering.

One for All: Towards Training One Graph Model for All Classification Tasks

1 code implementation29 Sep 2023 Hao liu, Jiarui Feng, Lecheng Kong, Ningyue Liang, DaCheng Tao, Yixin Chen, Muhan Zhang

For in-context learning on graphs, OFA introduces a novel graph prompting paradigm that appends prompting substructures to the input graph, which enables it to address varied tasks without fine-tuning.

Graph Contrastive Learning Meets Graph Meta Learning: A Unified Method for Few-shot Node Tasks

1 code implementation19 Sep 2023 Hao liu, Jiarui Feng, Lecheng Kong, DaCheng Tao, Yixin Chen, Muhan Zhang

In our study, we first identify two crucial advantages of contrastive learning compared to meta learning, including (1) the comprehensive utilization of graph nodes and (2) the power of graph augmentations.

Extending the Design Space of Graph Neural Networks by Rethinking Folklore Weisfeiler-Lehman

1 code implementation NeurIPS 2023 Jiarui Feng, Lecheng Kong, Hao liu, DaCheng Tao, Fuhai Li, Muhan Zhang, Yixin Chen

We theoretically prove that even if we fix the space complexity to $O(n^k)$ (for any $k\geq 2$) in $(k, t)$-FWL, we can construct an expressiveness hierarchy up to solving the graph isomorphism problem.

A Multi-View Joint Learning Framework for Embedding Clinical Codes and Text Using Graph Neural Networks

no code implementations27 Jan 2023 Lecheng Kong, Christopher King, Bradley Fritz, Yixin Chen

Learning to represent free text is a core task in many clinical machine learning (ML) applications, as clinical text contains observations and plans not otherwise available for inference.
