In text retrieval, the Word Mover’s distance (WMD) has recently emerged as the state-of-the art semantic- … 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 EMD-based similarity analysis (EMDSA) is an important and effective tool in many multimedia information retrieval and pattern recognition applications. … See more The concept was first introduced by Gaspard Monge in 1781, in the context of transportation theory.

One approach is to allow for a partial match, where dirt from the most massive distribution … See more The EMD can be computed by solving an instance of transportation problem, using any algorithm for minimum-cost flow problem, … 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
WebApr 4, 2012 · Your "distance" is mean (f) - mean (g). To minimize the total amount of earth moved without regard to how far it is moved, a greedy algorithm achieves the optimum, which is the statistical distance between the distributions. No algorithm needed here, since you only need to compute 2 expectations. WebJul 24, 2024 · The Greenland Ice Sheet holds enough water to raise the world’s sea level by over 7 meters (23 feet).
