Earth mover distance in r
WebBecause of this analogy, the metric is known in computer science as the earth mover's distance. The name "Wasserstein distance" was coined by R. L. Dobrushin in 1970, after learning of it in the work of Leonid Vaseršteĭn on Markov processes describing large systems of automata [1] (Russian, 1969). http://robotics.stanford.edu/~rubner/papers/rubnerIjcv00.pdf

WebApr 2, 2024 · So, unfortunately, the Euclidean distance erroneously suggests that h 3 is closer in similarity to h 1. On the other hand, the earth mover’s distance returns. EMD ( h 1, h 2) = 4.33333 , EMD ( h 1, h 3) = 5.0 . It correctly classifies h 2 as being closer in similarity to h 1, which makes the earth mover’s distance a much more useful ...
