Overview
This repository provides the necessary factory file that implements the Optimization of OT problems using Riemannian Manifold Optimization Framework. Details can be found in our work:
Bamdev Mishra, N. T. V. Satya Dev, Hiroyuki Kasai, Pratik Jawanpuria. Manifold Optimization for Optimal Transport, arXiv preprint arXiv:2103.00902, 2021.
Usage
The factory file is in compatible with the Pymanopt toolbox and can be easily integrated by placing it in the pymanopt/manifolds/ folder (As of the Pymanopt's release 7f7a022 origin/dev ). A helper file has been provided in the helpers directory explaining the usage of factory file.
For MATLAB implementation checkout matlab branch.
NOTE
For GPU based acceleration (cupy), set the environment variable USE_GPU_OPT to 1
