TiGer: Self-Supervised Purification for Time-evolving Graphs

Hyeonsoo Jo, Jongha Lee, Fanchen Bu +1

Time-evolving graphs, such as social and citation networks, often contain noise that distorts structural and temporal patterns, adversely affecting downstream tasks, such as node c…

On Measuring Unnoticeability of Graph Adversarial Attacks: Observations, New Measure, and Applications

Hyeonsoo Jo, Hyunjin Hwang, Fanchen Bu +3

Adversarial attacks are allegedly unnoticeable. Prior studies have designed attack noticeability measures on graphs, primarily using statistical tests to compare the topology of or…

Tackling Prevalent Conditions in Unsupervised Combinatorial Optimization: Cardinality, Minimum, Covering, and More

Fanchen Bu, Hyeonsoo Jo, Soo Yong Lee +2

Combinatorial optimization (CO) is naturally discrete, making machine learning based on differentiable optimization inapplicable. Karalias & Loukas (2020) adapted the probabilistic…

Robust Graph Clustering via Meta Weighting for Noisy Graphs

Hyeonsoo Jo, Fanchen Bu, Kijung Shin

How can we find meaningful clusters in a graph robustly against noise edges? Graph clustering (i.e., dividing nodes into groups of similar ones) is a fundamental problem in graph a…

SSumM: Sparse Summarization of Massive Graphs

Kyuhan Lee, Hyeonsoo Jo, Jihoon Ko +2

Given a graph G and the desired size k in bits, how can we summarize G within k bits, while minimizing the information loss? Large-scale graphs have become omnipresent, posing cons…
