Emd earth mover loss
Webnaturally extend the EMD for 1D distributions by allow-ing for asymmetry, in analogy to the pinball loss being an asymmetric generalization of the l1 loss. In Sec.2, we intro-duce the EMD and the pinball loss, and we define the Earth Mover’s Pinball Loss (EMPL) by combining the two. Then, we demonstrate the effectiveness of our method in three 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.

WebNov 22, 2016 · The Earth Mover's Distance (EMD) computes the optimal cost of transforming one distribution into another, given a known transport metric between them. In deep learning, the EMD loss allows us to embed information during training about the … WebThe function emd allows you to pass distributions, however, you need to provide the metric as an additional parameter. Also, when working with histograms as (density) distributions you need to normalize them. Not flattening the grey-scale images means that you compare 2D-histgramms which only works with pyemd.
