Abstract(in English) | Optimal transport (OT) has become a widely used tool to measure the discrepancy between probability distributionsin the machine learning field. For instance, OT is a popular loss function that quantifies the discrepancy between an empiricaldistribution and a parametric model. Recently, an entropic penalty term and the celebrated Sinkhorn algorithm have beencommonly used to approximate the original OT in a computationally efficient way. However, since the Sinkhorn algorithm runsa projection associated with the Kullback-Leibler divergence, it is often vulnerable to outliers. To overcome this problem, wepropose regularizing OT with the |
