WebMay 28, 2024 · $\begingroup$ Wasserstein's metric and earth mover's distance are two names for the same concept. $\endgroup$ – Dilip Sarwate. May 28, 2024 at 16:59 $\begingroup$ Thank you. I heard that the wasserstein metric is "a natural extension of the euclidean metric" ? I don't really get why? $\endgroup$ WebThe Earth Mover's Distance (EMD) is a distance measure between discrete, finite distributions The x distribution has an amount of mass or weight w i at position x i in RK, i=1,...,m, while the y distribution has weight u j at position y j, j=1,...,n. An example pair of distributions in R2 is shown below. Here x has m=2 masses and y has n=3 masses.
