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 ...

WebThe Earth mover’s distance is a distance measure between probability distributions. If we consider each probability mass function as a histogram of dirt, it is equal to the amount of work needed to optimally move the dirt of one histogram into the shape of the other. For categorical data, the “distance” between unequal symbols is unitary. 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 …
http://mkusner.github.io/publications/WMD.pdf WebThis is an implementation of the Earth Movers Distance, as described in . The EMD computes the distance between two distributions, which are represented by signatures. The signatures are sets of weighted features that capture the distributions. The features can be of any type and in any number of dimensions, and are defined by the user.
