报告摘要：Hyperbolic space has attracted attention in machine learning this decade since even extremely low-dimensional hyperbolic space succeeded in representing entities with a large-scale hierarchical structure. This talk aims to help the audience to understand hyperbolic space’s properties and why it can contribute to some machine learning areas. At the end of this talk, the audience will be expected to be able to

- Explain hyperbolic space’s exponential space growth property,

- Judge whether hyperbolic space can contribute to applications that they are interested in, including natural language processing, and

- Have clues to design a machine-learning model using hyperbolic space (if we have additional time).

While hyperbolic space is usually defined as a Riemannian manifold in differential geometry, this lecture does not assume the preliminary knowledge of differential geometry.
