Optimal Transport for Domain Adaptation [PDF]

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2017
Domain adaptation is one of the most challenging tasks of modern data analytics. If the adaptation is done correctly, models built on a specific data representation become more robust when confronted to data depicting the same classes, but described by another observation system.

RDAOT: Robust Unsupervised Deep Sub-Domain Adaptation Through Optimal Transport for Image Classification

open access: yesIEEE Access, 2023
In traditional machine learning, the training and testing data are assumed to come from the same independent and identical distributions. This assumption, however, does not hold up in real-world applications, as differences between the training and ...

Cortically Based Optimal Transport

open access: yesJournal of Mathematical Imaging and Vision, 2022
AbstractWe introduce a model for image morphing in the primary visual cortex V1 to perform completion of missing images in time. We model the output of simple cells through a family of Gabor filters and the propagation of the neural signal accordingly to the functional geometry induced by horizontal connectivity.

Sliced optimal transport sampling [PDF]

open access: yesACM Transactions on Graphics, 2020
In this paper, we introduce a numerical technique to generate sample distributions in arbitrary dimension for improved accuracy of Monte Carlo integration. We point out that optimal transport offers theoretical bounds on Monte Carlo integration error, and that the recently-introduced numerical framework of sliced optimal transport (SOT ...

On the Relation Between Optimal Transport and Schr\uf6dinger Bridges: A Stochastic Control Viewpoint [PDF]

open access: yes, 2015
We take a new look at the relation between the optimal transport problem and the Schr\uf6dinger bridge problem from a stochastic control perspective. Our aim is to highlight new connections between the two that are richer and deeper than those previously

Sliced optimal transport on the sphere

open access: yesInverse Problems, 2023
Abstract Sliced optimal transport reduces optimal transport on multi-dimensional domains to transport on the line. More precisely, sliced optimal transport is the concatenation of the well-known Radon transform and the cumulative density transform, which analytically yields the solutions of the reduced transport problems.

On the optimal design of wall-to-wall heat transport [PDF]

open access: yes, 2019
We consider the problem of optimizing heat transport through an incompressible fluid layer. Modeling passive scalar transport by advection-diffusion, we maximize the mean rate of total transport by a divergence-free velocity field.

Sparse Regularized Optimal Transport with Deformed q-Entropy

open access: yesEntropy, 2022
Optimal transport is a mathematical tool that has been a widely used to measure the distance between two probability distributions. To mitigate the cubic computational complexity of the vanilla formulation of the optimal transport problem, regularized ...
