WebWasserstein距离也叫做推土机距离(Earth Mover's distance),这也是由于它的推导过程可以很形象的用挖土填土来解释,这也是因为该距离定义中由一个分布转变为另一个分布所需要的代价和挖土填土的过程十分相似。考虑两个离散的分布P和Q. P_{1}=3,P_{2}=2,P_{3}=1,P_{4}=4 Web本文将讨论Earth Mover’s Distance (EMD),和欧式距离一样,它们都是一种距离度量的定义、可以用来测量某两个分布之间的距离。. EMD主要应用在图像处理和语音信号处理领域,在自然语言处理上很少有听说。. EMD 问题如下图所示. 给定两个签名 (或者叫分布、特征 …

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 D, the EMD is the minimum cost of turning one pile into the other; where the cost is assumed to be the amount of dirt moved times the distance by which it is moved. simple bingo board
