Data denoising with self consistency, variance maximization, and the Kantorovich dominance
Joshua Zoen-Git Hiew, Tongseok Lim, Brendan Pass +1
We introduce a new framework for data denoising, partially inspired by martingale optimal transport. For a given noisy distribution (the data), our approach involves finding the cl…

Dimension Reduction in Martingale Optimal Transport: Geometry and Robust Option Pricing
Joshua Zoen-Git Hiew, Tongseok Lim, Brendan Pass +1
This paper addresses the problem of robust option pricing within the framework of Vectorial Martingale Optimal Transport (VMOT). We investigate the geometry of VMOT solutions for $…

Remarks on multi-period martingale optimal transport
Brendan Pass, Joshua Hiew
We study the structural properties of multi-period martingale optimal transport (MOT). We develop new tools to address these problems, and use them to prove several uniqueness and…
