the global graph curvature ξG

[xjzhao001]

Thank you very much for sharing the code. I have a small question, where is the code for estimating the global graph curvature ξG?

Here is an example implementation:

This is simply applying Equation (3) in the product-space paper (https://openreview.net/pdf?id=HJxeWnCcF7)
