Word Mover’s Distance for Text Similarity by Nihit Saxena

WebThe Earth Mover's Distance (EMD) is a method to evaluate dissimilarity between two multi-dimensional distributions in some feature space where a distance measure between single features, which we call the ground distance is given. The EMD ``lifts'' this distance from individual features to full distributions. WebNotice that the third parameter of CalcEMD2 is the Euclidean Distance CV_DIST_L2. Another option for the third parameter is the Manhattan Distance CV_DIST_L1. I would also like to mention that I wrote the code to calculate the Earth Mover's distance of two 2D histograms in Python.
