GFK_torch

This is an PyTorch Implementation of Geodesic Flow Kernel (CVPR2012) wrapped from GFK_numpy.

Note: In the context of GFK algorithm, the Generalized SVD of matrix pair $\mathbf(A,B)$ can be degenerated into a SVD problem of ${A}^{-1}B$.

The standard GSVD is coming soon, or it can just be implemented in reference to Chapter2.6 and Chapter8.7 in book.
