WebBecause of this analogy, the metric is known in computer science as the earth mover's distance . The name "Wasserstein distance" was coined by R. L. Dobrushin in 1970, after learning of it in the work of Leonid Vaseršteĭn on Markov processes describing large systems of automata [1] (Russian, 1969). 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
