One Model, Many Graphs: Learning over Attributed Graphs across Heterogeneous Modalities with Vision-Language Models

arXiv:2607. 19128v1 Announce Type: new Abstract: Vision-language models (VLMs) provide a unified representation space for textual and visual information, yet their potential as general-purpose backbones for graph-structured data remains largely unexplored.

Path to Prior-Data Fitted Relational Models via Learned Latent Multi-table Representations

The paper investigates whether prior‑data‑fitted networks (PFNs) can be extended to graph‑based relational models. The authors pretrain a message‑passing foundation model, Griffin, on large synthetic relational databases and evaluate its frozen encoder on 16 real‑world relational classification tasks. A curriculum that starts with schema‑guided synthetic data and then uses schema‑agnostic data yields the best in‑context performance, outperforming real‑data‑only pretraining and other mixtures.

LLM as GNN: Graph Vocabulary Learning for Text-Attributed Graph Foundation Models

The paper introduces PromptGFM, a Graph Foundation Model designed for text‑attributed graphs (TAGs). It integrates Large Language Models (LLMs) and Graph Neural Networks (GNNs) through a Graph Understanding Module that prompts LLMs to emulate GNN workflows, and a Graph Inference Module that creates a language‑based graph vocabulary for better alignment and scalability. Experiments show PromptGFM outperforms existing methods and transfers effectively across various graphs and tasks.
