For the case where all weights are 1, Wasserstein distance will yield the measurement you're looking by doing something like the following. from scipy import stats u = [0.5,0.2,0.3] v = [0.5,0.3,0.2] # create and array with cardinality 3 (your metric space is 3-dimensional and # where distance between each pair of adjacent …

WebDec 2, 2024 · The Earth Mover’s Distance is Wasserstein with p = 1, usually denoted as W 1 or 1-Wasserstein. The 2-Wasserstein metric is computed like 1-Wasserstein, except instead of summing the work values, you sum the squared work values and then take the square root. The 3-Wasserstein would be the cube root of the sum of cubed work values, … In statistics, the earth mover's distance (EMD) is a measure of the distance between two probability distributions over a region D. 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 … See more Assume that we have a set of points in $${\textstyle \mathbb {R} ^{d}}$$ (dimension $${\textstyle d}$$). Instead of assigning one distribution to the set of points, we can cluster them and represent the point set in … See more The EMD can be computed by solving an instance of transportation problem, using any algorithm for minimum-cost flow problem, e.g. the network simplex algorithm See more An early application of the EMD in computer science was to compare two grayscale images that may differ due to dithering, blurring, or local deformations. In this case, the region is the image's domain, and the total amount of light (or ink) is the "dirt" to … See more Some applications may require the comparison of distributions with different total masses. One approach is to allow for a partial match, where dirt from the most massive distribution is rearranged to make the least massive, and any leftover "dirt" is discarded at no … See more EMD-based similarity analysis (EMDSA) is an important and effective tool in many multimedia information retrieval and pattern recognition applications. However, the computational cost … See more The concept was first introduced by Gaspard Monge in 1781, in the context of transportation theory.
