Earth mover’s distances on discrete surfaces
WebJul 27, 2014 · We introduce a novel method for computing the earth mover's distance (EMD) between probability distributions on a discrete surface. Rather than using a large linear program with a quadratic number of variables, we apply the theory of optimal … Webthe discrete version of the EMD. Indeed, the term “Earth Mover’s distance” seems to have been coined in [21] by researchers studying the discrete case, so the assumption of discrete domains is often implicit to its usage. One of the only known non-discrete cases with an explicit formula is if = R and D(x;y) = jx yj. Then W( ]; [) = Z F](y ...

WebThe Earth mover’s distance is a distance measure between probability distributions. If we consider each probability mass function as a histogram of dirt, it is equal to the amount of work needed to optimally move the dirt of one histogram into the shape of the other. For categorical data, the “distance” between unequal symbols is unitary.
