Metric-Preserving Reduction of Earth Mover's Distance
نویسندگان
چکیده
We prove that the earth mover’s distance problem reduces to a problem with half the number of constraints regardless of the ground distance, and propose a further reduced formulation when the ground distance comes from a graph with a homogeneous neighborhood structure. We also propose to apply our formulation to the non-negative matrix factorization.

Earth Mover's Distance and Equivalent Metrics for Spaces with Semigroups
introduce a multi-scale metric on a space equipped with a diffusion semigroup. We prove, under some technical conditions, that the norm dual to the space of Lipschitz functions with respect to this metric is equivalent to two other norms, one of which is a weighted sum of the averages at each scale, and one of which is a weighted sum of the difference of averages across scales. The notion of 's...
متن کاملVideo-Based Face Recognition Using Earth Mover's Distance
In this paper, we present a novel approach of using Earth Mover’s Distance for video-based face recognition. General methods can be classified into sequential approach and batch approach. Batch approach is to compute a similarity function between two videos. There are two classical batch methods. The one is to compute the angle between subspaces, and the other is to find K-L divergence between ...
متن کاملSupervised Earth Mover's Distance Learning and Its Computer Vision Applications
Earth Mover’s Distance (EMD) is an intuitive and natural distance metric for comparing two histograms or probability distributions. We propose to jointly optimize the ground distance matrix and the EMD flow-network based on partial ordering of histogram distances in an optimization framework. Two applications in computer vision are used to demonstrate the effectiveness of the algorithm: firstly...
متن کاملEarth Mover's Distance Yields Positive Definite Kernels For Certain Ground Distances
Positive definite kernels are an important tool in machine learning that enable efficient solutions to otherwise difficult or intractable problems by implicitly linearizing the problem geometry. In this paper we develop a set-theoretic interpretation of the Earth Mover’s Distance (EMD) that naturally yields metric and kernel forms of EMD as generalizations of elementary set operations. In parti...
متن کاملComparing Fuzzy, Probabilistic, and Possibilistic Partitions Using the Earth Mover's Distance
A number of noteworthy techniques have been put forth recently in different research fields for comparing clusterings. Herein, we introduce a new method for comparing soft (fuzzy, probabilistic and possibilistic) partitions based on the earth mover’s distance (EMD) and the ordered weighted average (OWA). The proposed method is a metric, depending on the ground distance, for all but possibilisti...
