Fast Sinkhorn II: Collinear Triangular Matrix and Linear Time Accurate Computation of Optimal Transport
Qichen Liao, Zihao Wang, Jing Chen +3
In our previous work [arXiv:2202.10042], the complexity of Sinkhorn iteration is reduced from to the optimal by leveraging the special structure of the kernel matri…

The Wasserstein-Fisher-Rao metric for waveform based earthquake location
D. T. Zhou, J. Chen, H. Wu +2
In our previous work [Chen el al., J. Comput. Phys., 373(2018)], the quadratic Wasserstein metric is successfully applied to the earthquake location problem. The actual earthquake…
