TaLK: Text-attributed Graph Dataset Distillation via Coupling Language Model with Graph-Aware Kernel

Yeongho Kim, Yeonje Choi, Kijung Shin

Text-attributed graphs (TAGs) are widely used in many real-world domains, and learning on TAGs requires jointly modeling text semantics and graph structure. A standard approach for…

SLeDGe: Semi-Supervised Learning on Data Streams with Graph Structure Learning

Heechan Moon, Kijung Shin

Semi-supervised learning (SSL) on data streams is challenging due to the continuous evolution of high-volume data and the scarcity of labels. Existing methods are limited in levera…

On the Memorization Behavior of LLMs in Generative Recommendation: Observations, Implications, and Training Strategies

Sunwoo Kim, Sunkyung Lee, Clark Mingxuan Ju +5

Generative recommendation (GR) has emerged as a promising direction for recommender systems. Recently, large language models (LLMs) have been increasingly adopted for GR, as their…

A Survey on Centrality and Importance Measures in Hypergraphs: Categorization and Empirical Insights

Jaewan Chun, Fanchen Bu, Yeongho Kim +3

Identifying central entities and interactions is a fundamental problem in network science. While well-studied for graphs (pairwise relations), many biological and social systems ex…

Edge Probability Graph Models Beyond Edge Independency: Concepts, Analyses, and Algorithms

Fanchen Bu, Ruochen Yang, Paul Bogdan +1

Desirable random graph models (RGMs) should (i) reproduce common patterns in real-world graphs (e.g., power-law degrees, small diameters, and high clustering), (ii) generate variab…

'Hello, World!': Making GNNs Talk with LLMs

Sunwoo Kim, Soo Yong Lee, Jaemin Yoo +1

While graph neural networks (GNNs) have shown remarkable performance across diverse graph-related tasks, their high-dimensional hidden representations render them black boxes. In t…
