WebThe Earth Mover's Distance (EMD) is a method to evaluate dissimilarity between two multi-dimensional distributions in some feature space where a distance measure between … Weban O(1= )-distortion embedding from the earth-mover metric EMD on the grid [ ]2 to ‘ O( ) 1 EEMD (where EEMDis a norm that generalizes earth-mover distance). This embedding is stronger (and simpler) than the sketching algorithm of Andoni et al [4], which maps EMD with O(1= )approximation into sketches of size O( ). 1 Introduction
