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

ICLR 2025poster

Foundation models, such as Large Language Models (LLMs) or Large Vision Models (LVMs), have emerged as one of the most powerful tools in the respective fields. However, unlike text and image data, graph data do not have a definitive structure, posing great challenges to developing a Graph Foundation…

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

ICLR 2024spotlight

Designing a single model to address multiple tasks has been a long-standing objective in artificial intelligence. Recently, large language models have demonstrated exceptional capability in solving different tasks within the language domain. However, a unified model for various graph tasks remains u…

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

NeurIPS 2023poster

Message passing neural networks (MPNNs) have emerged as the most popular framework of graph neural networks (GNNs) in recent years. However, their expressive power is limited by the 1-dimensional Weisfeiler-Lehman (1-WL) test. Some works are inspired by $k$-WL/FWL (Folklore WL) and design the corres…

MAG-GNN: Reinforcement Learning Boosted Graph Neural Network

NeurIPS 2023poster

While Graph Neural Networks (GNNs) recently became powerful tools in graph learning tasks, considerable efforts have been spent on improving GNNs' structural encoding ability. A particular line of work proposed subgraph GNNs that use subgraph information to improve GNNs' expressivity and achieved gr…

Geodesic Graph Neural Network for Efficient Graph Representation Learning

NeurIPS 2022accept

Graph Neural Networks (GNNs) have recently been applied to graph learning tasks and achieved state-of-the-art (SOTA) results. However, many competitive methods run GNNs multiple times with subgraph extraction and customized labeling to capture information that is hard for normal GNNs to learn. Such…

Manipulating Elections by Changing Voter Perceptions

IJCAI 2022poster

The integrity of elections is central to democratic systems. However, a myriad of malicious actors aspire to influence election outcomes for financial or political benefit. A common means to such ends is by manipulating perceptions of the voting public about select candidates, for example, through m…
