Decreasing Entropic Regularization Averaged Gradient for Semi-Discrete Optimal Transport

#705 · Ferdinand Genans, Antoine Godichon-Baggioni, François-Xavier Vialard, Olivier Wintenberger

We introduce and analyze a stochastic gradient descent method for solving semi-discrete optimal transport, based on a decreasing regularization scheme.
