Functional Optimal Transport: Mapping Estimation and Domain Adaptation for Functional data.

2021 · arXiv (Cornell University)

We introduce a formulation of optimal transport problem for distributions on function spaces, where the stochastic map between functional domains can be partially represented in terms of an (infinite-dimensional) Hilbert-Schmidt operator mapping a Hilbert space …

Robust Reinforcement Learning as a Stackelberg Game via Adaptively-Regularized Adversarial Training

2022 · arXiv (Cornell University)

Robust Reinforcement Learning (RL) focuses on improving performances under model errors or adversarial attacks, which facilitates the real-life deployment of RL agents. Robust Adversarial Reinforcement Learning (RARL) is one of the most popular frameworks for …
