WebThis is an implementation of the Earth Movers Distance, as described in . 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.
Web2.2. Earth Mover’s distance As a first step towards solving Eq. (2), we introduce the EMD (Rubner et al.,2000), which is a distance measure be-tween probability distributions rooted in the Optimal Trans-portation problem (Villani,2009).
