Reference to the method implemented?

[usptact]

Hi,

Thanks a lot for the implementation of graph to vector method. I am vaguely familiar with several methods, e.g. Laplacian Eigenmaps and similar methods. The implemented method in this module looks like is matrix factorization style algorithm (?) with square loss (?).

It would be great just to add a reference to a paper/blog which actually describes the method with equations.

Thanks
