http://robotics.stanford.edu/~scohen/research/emdg/emd.html WebAug 13, 2024 · So, in this blog, we will discuss the Earthmover’s distance also known as Wasserstein metric which is more suitable for finding distance or similarity between the distributions. This concept was first introduced by Gaspard Monge in 1781, in the context of transportation theory ( Wikipedia ). Let’s discuss the main concept behind this.
WebThe x distribution has an amount of mass or weight w i at position x i in R K, i=1,...,m, while the y distribution has weight u j at position y j, j=1,...,n.An example pair of distributions in R 2 is shown below.. Here x has m=2 masses and y has n=3 masses. The circle centers are the points (mass locations) of the distributions. The area of a circle is proportional to the … 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.
