Hypercore Decomposition for Non-Fragile Hyperedges: Concepts, Algorithms, Observations, and Applications

Fanchen Bu, Geon Lee, Kijung Shin

Hypergraphs are a powerful abstraction for modeling high-order relations, which are ubiquitous in many fields. A hypergraph consists of nodes and hyperedges (i.e., subsets of nodes…

Set2Box: Similarity Preserving Representation Learning of Sets

Geon Lee, Chanyoung Park, Kijung Shin

Sets have been used for modeling various types of objects (e.g., a document as the set of keywords in it and a customer as the set of the items that she has purchased). Measuring s…

HashNWalk: Hash and Random Walk Based Anomaly Detection in Hyperedge Streams

Geon Lee, Minyoung Choe, Kijung Shin

Sequences of group interactions, such as emails, online discussions, and co-authorships, are ubiquitous; and they are naturally represented as a stream of hyperedges. Despite their…
