It has been quite stable in the last months +but kept the beta flag in its Pypi classifiers until now. + +Note that this release will be the last one supporting officially Python 2.7 (See +https://python3statement.org/ for more reasons). For next release we will keep +the travis tests for Python 2 but will make them non necessary for merge in 2020. + +The features are never complete in a toolbox designed for solving mathematical +problems and research but with the new contributions we now implement algorithms and solvers +from 24 scientific papers (listed in the README.md file). New features include a +direct implementation of the [empirical Sinkhorn divergence](https://pot.readthedocs.io/en/latest/all.html#ot.bregman.empirical_sinkhorn_divergence) +, a new efficient (Cython implementation) solver for [EMD in 1D](https://pot.readthedocs.io/en/latest/all.html#ot.lp.emd_1d) +and corresponding [Wasserstein +1D](https://pot.readthedocs.io/en/latest/all.html#ot.lp.wasserstein_1d). We now also +have implementations for [Unbalanced OT](https://github.com/rflamary/POT/blob/master/notebooks/plot_UOT_1D.ipynb) +and a solver for [Unbalanced OT barycenters](https://github.com/rflamary/POT/blob/master/notebooks/plot_UOT_barycenter_1D.ipynb). +A new variant of Gromov-Wasserstein divergence called [Fused +Gromov-Wasserstein](https://pot.readthedocs.io/en/latest/all.html?highlight=fused_#ot.gromov.fused_gromov_wasserstein) + has been also contributed with exemples of use on [structured data](https://github.com/rflamary/POT/blob/master/notebooks/plot_fgw.ipynb) +and computing [barycenters of labeld graphs](https://github.com/rflamary/POT/blob/master/notebooks/plot_barycenter_fgw.ipynb). + + +A lot of work has been done on the documentation with several new +examples corresponding to the new features and a lot of corrections for the +docstrings. But the most visible change is a new +[quick start guide](https://pot.readthedocs.io/en/latest/quickstart.html) for +POT that gives several pointers about which function or classes allow to solve which +specific OT problem. When possible a link is provided to relevant examples. + +We will also provide with this release some pre-compiled Python wheels for Linux +64bit on +github and pip. This will simplify the install process that before required a C +compiler and numpy/cython already installed. + +Finally we would like to acknowledge and thank the numerous contributors of POT +that has helped in the past build the foundation and are still contributing to +bring new features and solvers to the library. + + + +#### Features + +* Add compiled manylinux 64bits wheels to pip releases (PR #91) +* Add quick start guide (PR #88) +* Make doctest work on travis (PR #90) +* Update documentation (PR #79, PR #84) +* Solver for EMD in 1D (PR #89) +* Solvers for regularized unbalanced OT (PR #87, PR#99) +* Solver for Fused Gromov-Wasserstein (PR #86) +* Add empirical Sinkhorn and empirical Sinkhorn divergences (PR #80) + + +#### Closed issues + +- Issue #59 fail when using "pip install POT" (new details in doc+ hopefully + wheels) +- Issue #85 Cannot run gpu modules +- Issue #75 Greenkhorn do not return log (solved in PR #76) +- Issue #82 Gromov-Wasserstein fails when the cost matrices are slightly different +- Issue #72 Macosx build problem + + ## 0.5.0 Year 2 *Sep 2018* |
