Recent years have witnessed significant advancements in graph machine learning (GML), with its applications spanning numerous domains. However, the focus of GML has predominantly been on developing powerful models, often overlooking a crucial initial step: constructing suitable graphs from common data formats, such as tabular data. This construction process is fundamental to applying graphbased yet it remains largely understudied and lacks formalization. Our research aims address this gap by...

A fundamental challenge in understanding graph neural networks (GNNs) lies characterizing their optimization dynamics and loss landscape geometry, critical for improving interpretability robustness. While mode connectivity, a lens analyzing geometric properties of landscapes has proven insightful other deep learning architectures, its implications GNNs remain unexplored. This work presents the first investigation connectivity GNNs. We uncover that exhibit distinct non-linear diverging from...

Given the ubiquity of graph data and its applications in diverse domains, building a Graph Foundation Model (GFM) that can work well across different graphs tasks with unified backbone has recently garnered significant interests. A major obstacle to achieving this goal stems from fact domains often exhibit node features. Inspired by multi-modal models align modalities natural language, text been adopted provide feature space for graphs. Despite great potential these text-space GFMs, current...
