Wasserstein Distance on Configuration Space [PDF]

open access: yesPotential Analysis, 2008
We investigate here the optimal transportation problem on configuration space for the quadratic cost. It is shown that, as usual, provided that the corresponding Wasserstein is finite, there exists one unique optimal measure and that this measure is supported by the graph of the derivative (in the sense of the Malliavin calculus) of a ``concave'' (in a

Generative Modeling Using the Sliced Wasserstein Distance [PDF]

open access: yes2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition, 2018
Generative Adversarial Nets (GANs) are very successful at modeling distributions from given samples, even in the high-dimensional case. However, their formulation is also known to be hard to optimize and often not stable.

Dimensional contraction via Markov transportation distance [PDF]

open access: yes, 2013
It is now well known that curvature conditions \`a la Bakry-Emery are equivalent to contraction properties of the heat semigroup with respect to the classical quadratic Wasserstein distance.

Generating Adversarial Samples With Constrained Wasserstein Distance

open access: yesIEEE Access, 2019
In recent years, deep neural network (DNN) approaches prove to be useful in many machine learning tasks, including classification. However, small perturbations that are carefully crafted by attackers can lead to the misclassification of the images ...

MRWM: A Multiple Residual Wasserstein Driven Model for Image Denoising

open access: yesIEEE Access, 2022
Residual histograms can provide valuable information for vision research. However, current image restoration methods have not fully exploited the potential of multiple residual histograms, especially their role as overall regularization constraints.

Proxying credit curves via Wasserstein distances

open access: yesAnnals of Operations Research, 2022
AbstractCredit risk plays a key role in financial modeling, and financial institutions are required to incorporate it in their pricing, as well as in capital requirement calculations. A common manner to extract credit worthiness information for existing and potential counterparties is based on the Credit Default Swap (CDS) market.

Graded persistence diagrams and persistence landscapes

open access: yes, 2021
We introduce a refinement of the persistence diagram, the graded persistence diagram. It is the Mobius inversion of the graded rank function, which is obtained from the rank function using the unary numeral system.

Optimal transport in competition with reaction: the Hellinger-Kantorovich distance and geodesic curves [PDF]

open access: yes, 2015
We discuss a new notion of distance on the space of finite and nonnegative measures which can be seen as a generalization of the well-known Kantorovich-Wasserstein distance.

Kernel Wasserstein Distance

open access: yes, 2019
The Wasserstein distance is a powerful metric based on the theory of optimal transport. It gives a natural measure of the distance between two distributions with a wide range of applications. In contrast to a number of the common divergences on distributions such as Kullback-Leibler or Jensen-Shannon, it is (weakly) continuous, and thus ideal for ...
