Are there any active communities working in the space of hyperbolic deep learning? I’m specifically interested in Flux-compatible libraries which define the basic DL operations for either the Poincare or Lorentz hyperbolic spaces: addition, multiplication, softmax, etc. Bonus points for hyperbolic versions of Adam, etc, along with docs/examples.

If these don’t exist and I was to build them, is there an existing org where the package could/should live?
