Changing the curvature

[elichienxD]

Hi,

Thanks for the great work and well documented code.

Currently, it seems like the hyperbolic embedding lives in a Poincare disk/ball with curvature -1. In my own application, I would like to work with arbitrary curvature -c, c>0.

So my question is can I do so by just modifying utils/poincare.py? Or I also need to make changes in optim and elsewhere?

Thanks in advance for your valuable time.

Best,
Eli
