Mixed-Precision GPU Acceleration for Large-Scale Minimum Enclosing Ball Problems
Ling Liang, Lei Yang
A mixed-precision GPU-oriented optimization framework is developed for computing the minimum enclosing ball of a collection of balls. The approach is built on an equivalent second-…

A Provably Convergent and Practical Algorithm for Gromov--Wasserstein Optimal Transport
Ling Liang, Lei Yang
Gromov--Wasserstein optimal transport (GWOT) aligns metric measure spaces by matching their within-domain relational structures, but large-scale GWOT remains challenging because it…

Fast and Effective Computation of Generalized Symmetric Matrix Factorization
Lei Yang, Han Wan, Min Zhang +1
In this paper, we study a nonconvex, nonsmooth, and non-Lipschitz generalized symmetric matrix factorization model that unifies a broad class of matrix factorization formulations a…
