Detecting changes in forced climate attractors with Wasserstein distance [PDF]

open access: yesNonlinear Processes in Geophysics, 2017
The climate system can been described by a dynamical system and its associated attractor. The dynamics of this attractor depends on the external forcings that influence the climate.

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 ...

Lidar Upsampling With Sliced Wasserstein Distance

open access: yesIEEE Robotics and Automation Letters, 2023
Lidar became an important component of the perception systems in autonomous driving. But challenges of training data acquisition and annotation made emphasized the role of the sensor to sensor domain adaptation. In this work, we address the problem of lidar upsampling.

The Wasserstein distance to the circular law

open access: yesAnnales de l'Institut Henri Poincaré, Probabilités et Statistiques, 2023
We investigate the Wasserstein distance between the empirical spectral distribution of non-Hermitian random matrices and the Circular Law. For general entry distributions, we obtain a nearly optimal rate of convergence in 1-Wasserstein distance of order $n^{-1/2+ε}$ and we prove that the optimal rate $n^{-1/2}$ is attained by Ginibre matrices.

Fast Topological Clustering with Wasserstein Distance

open access: yesCoRR, 2021
The topological patterns exhibited by many real-world networks motivate the development of topology-based methods for assessing the similarity of networks. However, extracting topological structure is difficult, especially for large and dense networks whose node degrees range over multiple orders of magnitude.

Scalar conservation laws seen as gradient flows: known results and new perspectives

open access: yesESAIM: Proceedings and Surveys, 2016
We review some results in the literature which attempted (only partly successfully) at linking the theory of scalar conservation laws with the Wasserstein gradient flow theory.

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.

Composition‐Aware Cross‐Sectional Integration for Spatial Transcriptomics

open access: yesAdvanced Intelligent Discovery, EarlyView.
Multi‐section spatial transcriptomics demands coherent cell‐type deconvolution, domain detection, and batch correction, yet existing pipelines treat these tasks separately. FUSION unifies them within a composition‐aware latent framework, modeling reads as cell‐type–specific topics and clustering in embedding space.

Towards Inverse Modeling of Landscapes Using the Wasserstein Distance

open access: yesGeophysical Research Letters, 2023
Extricating histories of uplift and erosion from landscapes is crucial for many branches of the Earth sciences. An objective way to calculate such histories is to identify calibrated models that minimize misfit between observations (e.g., topography) and
