High-dimensional Optimal Density Control with Wasserstein Metric Matching

Shaojun Ma, Mengxue Hou, Xiaojing Ye +1

We present a novel computational framework for density control in high-dimensional state spaces. The considered dynamical system consists of a large number of indistinguishable age…

Mean Field Game GAN

Shaojun Ma, Haomin Zhou, Hongyuan Zha

We propose a novel mean field games (MFGs) based GAN(generative adversarial network) framework. To be specific, we utilize the Hopf formula in density space to rewrite MFGs as a pr…

Learning High Dimensional Wasserstein Geodesics

Shu Liu, Shaojun Ma, Yongxin Chen +2

We propose a new formulation and learning strategy for computing the Wasserstein geodesic between two probability distributions in high dimensions. By applying the method of Lagran…

Learning Cost Functions for Optimal Transport

Shaojun Ma, Haodong Sun, Xiaojing Ye +2

Inverse optimal transport (OT) refers to the problem of learning the cost function for OT from observed transport plan or its samples. In this paper, we derive an unconstrained con…

Learning Stochastic Behaviour from Aggregate Data

Shaojun Ma, Shu Liu, Hongyuan Zha +1

Learning nonlinear dynamics from aggregate data is a challenging problem because the full trajectory of each individual is not available, namely, the individual observed at one tim…
