Approximating High-Dimensional Earth Mover's Distance as Fast as Closest Pair
Lorenzo Beretta, Vincent Cohen-Addad, Rajesh Jayaram +1
We give a reduction from -approximate Earth Mover's Distance (EMD) to -approximate Closest Pair (CP). As a consequence, we improve the fastest kno…

Approximate Earth Mover's Distance in Truly-Subquadratic Time
Lorenzo Beretta, Aviad Rubinstein
We design an additive approximation scheme for estimating the cost of the min-weight bipartite matching problem: given a bipartite graph with non-negative edge costs and $\varepsil…

Locally Uniform Hashing
Ioana O. Bercea, Lorenzo Beretta, Jonas Klausen +2
Hashing is a common technique used in data processing, with a strong impact on the time and resources spent on computation. Hashing also affects the applicability of theoretical re…
