The $p$-Wasserstein distance measures the cost of optimally transporting one distribution to another, where the cost of moving a unit mass from $a$ to $b$ is the $p^{th}$ power of the ground distance $\mathrm{d}(a,b)$ between them. Despite its strong theoretical properties, its use in practice --…
Optimal Transport is a popular distance metric for measuring similarity between distributions. Exact and approximate combinatorial algorithms for computing the optimal transport distance are hard to parallelize. This has motivated the development of numerical solvers (e.g. Sinkhorn method) that can…
Maximum cardinality bipartite matching is an important graph optimization problem with several applications. For instance, maximum cardinality matching in a $\delta$-disc graph can be used in the computation of the bottleneck matching as well as the $\infty$-Wasserstein and the Lévy-Prokhorov distan…
Transportation cost is an attractive similarity measure between probability distributions due to its many useful theoretical properties. However, solving optimal transport exactly can be prohibitively expensive. Therefore, there has been significant effort towards the design of scalable approximati…
