Relative Entropy-Regularized Optimal Transport on a Graph: a new algorithm and an experimental comparison

no code implementations23 Aug 2021 Sylvain Courtain, Guillaume Guex, Ilkka Kivimaki, Marco Saerens

Following [21, 23], the present work investigates a new relative entropy-regularized algorithm for solving the optimal transport on a graph problem within the randomized shortest paths formalism.

Randomized Shortest Paths with Net Flows and Capacity Constraints

no code implementations4 Oct 2019 Sylvain Courtain, Pierre Leleux, Ilkka Kivimaki, Guillaume Guex, Marco Saerens

The framework assumes a unit flow injected into a source node and collected from a target node with flows minimizing the expected transportation cost, together with a relative entropy regularization term.
