Link prediction with hyperbolic geometry [PDF]
Physical Review Research, 2020 Link prediction is a paradigmatic problem in network science with a variety of applications. In latent space network models this problem boils down to ranking pairs of nodes in the order of increasing latent distances between them. The network model with

High Dimensional Hyperbolic Geometry of Complex Networks
Mathematics, 2020 High dimensional embeddings of graph data into hyperbolic space have recently been shown to have great value in encoding hierarchical structures, especially in the area of natural language processing, named entity recognition, and machine generation of ...

Routing Strategy of Integrated Satellite-Terrestrial Network Based on Hyperbolic Geometry
IEEE Access, 2020 The integrated satellite-terrestrial network has the characteristics of large scale, complex, high dynamic and heterogeneousness. Adopting traditional routing methods in the integrated satellite-terrestrial network will cause problems of poor scalability

Hippocampal spatial representations exhibit a hyperbolic geometry that expands with experience. [PDF]
Nat Neurosci, 2023 Most spatial navigation studies assume a linear map of space. This study reports that neural representations of space follow non-linear hyperbolic coordinates. These representations also expand with experience along a maximally informative limit.

Application of hyperbolic geometry in link prediction of multiplex networks. [PDF]
Sci Rep, 2019 Recently multilayer networks are introduced to model real systems. In these models the individuals make connection in multiple layers. Transportation networks, biological systems and social networks are some examples of multilayer networks.

Hyperbolic geometry of the olfactory space. [PDF]
Sci Adv, 2018 Natural odors and human perceptual descriptions of odors can be represented within three-dimensional hyperbolic space. In the natural environment, the sense of smell, or olfaction, serves to detect toxins and judge nutritional content by taking advantage

Modeling Scale-free Graphs with Hyperbolic Geometry for Knowledge-aware Recommendation [PDF]
Web Search and Data Mining, 2021 Aiming to alleviate data sparsity and cold-start problems of tradi- tional recommender systems, incorporating knowledge graphs (KGs) to supplement auxiliary information has recently gained considerable attention.

Detecting hyperbolic geometry in networks: why triangles are not enough [PDF]
Physical Review E, 2022 In the past decade, geometric network models have received vast attention in the literature. These models formalize the natural idea that similar vertices are likely to connect.
