Bending the Future: Autoregressive Modeling of Temporal Knowledge Graphs in Curvature-Variable Hyperbolic Spaces

AKBC, 2022
We use more expressive hyperbolic spaces to tackle temporal knowledge graph reasoning with global representations to model chronological hierarchies between KGs, and local ones to model diverse hierarchical levels of KGs by variable curvatures of hyperbolic embeddings.
