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. WebJun 19, 2024 · What is Word Mover’s Distance (WMD)? Word Mover’s Distance is like Earth Movers Distance but between text documents. We use word vectors like for example Word2vec, FastText, or StarSpace embeddings. The probability distribution’s support is over word vectors of the document’s words; value is normalized frequency of unique words in …

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 … See more • C code for the Earth Mover's Distance (archived here) • Python implementation with references • Python2 wrapper for the C implementation of the Earth Mover's Distance See more Some applications may require the comparison of distributions with different total masses.

So if I understand you correctly, you're trying to transport the sampling distribution, i.e. calculate the distance for a setup where all clusters have weight 1. In general, you can treat the calculation of the EMD as an instance of minimum cost flow, and in your case, this boils down to the linear assignment problem: Your two arrays ... data visualization designer what is that
