This toolbox benefit a lot from open source research and we would like to thank the following persons for providing some code (in various languages):
- Gabriel Peyré (Wasserstein Barycenters in Matlab)
- Mathieu Blondel (original implementation smooth OT)
- Nicolas Bonneel (C++ code for EMD)
- Marco Cuturi (Sinkhorn Knopp in Matlab/Cuda)
POT has benefited from the financing or manpower from the following partners:
