The EMD computes the distance between two distributions, which are represented by signatures. The signatures are sets of weighted features that capture the distributions. The features can be of any type and in any number of dimensions, and are defined by the user.

In mathematics, this is known as the Wasserstein metric. Informally, if the distributions are interpreted as two different ways of piling up a certain amount of earth (dirt) over the region D, the EMD is the minimum cost of turning one pile into the other; where the cost is assumed to be the amount of dirt moved times the distance by which it is moved. how do you spell pravastatinWeb本文将讨论Earth Mover’s Distance (EMD),和欧式距离一样,它们都是一种距离度量的定义、可以用来测量某两个分布之间的距离。.
