Web18 de ago. de 2024 · To this end, we propose a Gaussian Receptive Field based Label Assignment (RFLA) strategy for tiny object detection. Specifically, RFLA first utilizes the prior information that the feature receptive field follows Gaussian distribution. Then, instead of assigning samples with IoU or center sampling strategy, a new Receptive Field Distance … WebThe use of the Wasserstein distance for GoF testing has been considered mostly for univariate distributions (Munk and Czado, 1998; del Barrio et al., 1999;delBarrioetal.,2000;delBarrio,Gin´eandUtzet,2005).Forthemultivari-
WebIn computer science, the earth mover's distance (EMD) is a distance-like measure of dissimilarity between two frequency distributions, densities, or measures over a region D.For probability distributions and normalized histograms, it reduces to the Wasserstein metric. Informally, if the distributions are interpreted as two different ways of piling up earth (dirt) … Web1 de ago. de 2024 · Perhaps the easiest spot to see the difference between Wasserstein distance and KL divergence is in the multivariate Gaussian case where both have closed form solutions.
