Their use dates back to 1781. Recent years have witnessed a new revolution in the spread of OT, thanks to the emergence of approximate solvers that can scale to sizes and dimensions that are relevant to data sciences.
WebOutlier-Robust Optimal Transport computational OT methods (Peyré & Cuturi, 2024). In this paper, we propose a modification of OT to address its sensitivity to outliers. Our formulation can be used as a loss in equation 1.2, so that it is robust to a small fraction of outliers in the data. For simplicity, we consider the - Web3 Robust Optimal Transport Our objective is to handle outliers in deep learning applications involving OT. For this, we use relaxed OT formulations. In this section, we first formally define the outlier model we use. Then, we discuss the existing marginal relaxation formulations in OT and the issues that arise in deep learning when
