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…

Beyond Learning from Next Item: Sequential Recommendation via Personalized Interest Sustainability

Dongmin Hyun, Chanyoung Park, Junsu Cho +1

Sequential recommender systems have shown effective suggestions by capturing users' interest drift. There have been two groups of existing sequential models: user- and item-centric…

LTE4G: Long-Tail Experts for Graph Neural Networks

Sukwon Yun, Kibum Kim, Kanghoon Yoon +1

Existing Graph Neural Networks (GNNs) usually assume a balanced situation where both the class distribution and the node degree distribution are balanced. However, in real-world si…

GraFN: Semi-Supervised Node Classification on Graph with Few Labels via Non-Parametric Distribution Assignment

Junseok Lee, Yunhak Oh, Yeonjun In +3

Despite the success of Graph Neural Networks (GNNs) on various applications, GNNs encounter significant performance degradation when the amount of supervision signals, i.e., number…

AHP: Learning to Negative Sample for Hyperedge Prediction

Hyunjin Hwang, Seungwoo Lee, Chanyoung Park +1

Hypergraphs (i.e., sets of hyperedges) naturally represent group relations (e.g., researchers co-authoring a paper and ingredients used together in a recipe), each of which corresp…

Shift-Robust Node Classification via Graph Adversarial Clustering

Qi Zhu, Chao Zhang, Chanyoung Park +2

Graph Neural Networks (GNNs) are de facto node classification models in graph structured data. However, during testing-time, these algorithms assume no data shift, i.e., $\Pr_\text…
