Abstract
We provide the first sub-linear sketching algorithm for estimating the planar Earth-Mover Distance with a constant approximation. For sets living in the two-dimensional grid [¿]2, we achieve space ¿¿ for approximation O(1/¿), for any desired 0 < ¿ < 1. Our sketch has immediate applications to the streaming and nearest neighbor search problems.
