Solving a Special Type of Optimal Transport Problem by a Modified Hungarian Algorithm

Yiling Xie, Yiling Luo, Xiaoming Huo

Computing the empirical Wasserstein distance in the Wasserstein-distance-based independence test is an optimal transport (OT) problem with a special structure. This observation ins…

The Directional Bias Helps Stochastic Gradient Descent to Generalize in Kernel Regression Models

Yiling Luo, Xiaoming Huo, Yajun Mei

We study the Stochastic Gradient Descent (SGD) algorithm in nonparametric statistics: kernel regression in particular. The directional bias property of SGD, which is known in the l…

Implicit Regularization Properties of Variance Reduced Stochastic Mirror Descent

Yiling Luo, Xiaoming Huo, Yajun Mei

In machine learning and statistical data analysis, we often run into objective function that is a summation: the number of terms in the summation possibly is equal to the sample si…
