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. WebApr 16, 2024 · Approximating the Earth Mover's Distance between sets of geometric objects. Given two distributions and of equal total mass, the Earth Mover's Distance measures the cost of transforming one distribution into the other, where the cost of moving a unit of mass is equal to the distance over which it is moved. We give approximation …
