Hyperbolic Heterogeneous Graph Transformer
Jongmin Park, Seunghoon Han, Hyewon Lee +2
In heterogeneous graphs, we can observe complex structures such as tree-like or hierarchical structures. Recently, the hyperbolic space has been widely adopted in many studies to e…

Metapath-based Hyperbolic Contrastive Learning for Heterogeneous Graph Embedding
Jongmin Park, Seunghoon Han, Won-Yong Shin +1
The hyperbolic space, characterized by a constant negative curvature and exponentially expanding space, aligns well with the structural properties of heterogeneous graphs. However,…

Multi-Hyperbolic Space-based Heterogeneous Graph Attention Network
Jongmin Park, Seunghoon Han, Jong-Ryul Lee +1
To leverage the complex structures within heterogeneous graphs, recent studies on heterogeneous graph embedding use a hyperbolic space, characterized by a constant negative curvatu…
