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