Convergence Theorems for Entropy-Regularized and Distributional Reinforcement Learning
Yash Jhaveri, Harley Wiltzer, Patrick Shafto +2
In the pursuit of finding an optimal policy, reinforcement learning (RL) methods generally ignore the properties of learned policies apart from their expected return. Thus, even wh…
Action Gaps and Advantages in Continuous-Time Distributional Reinforcement Learning
Harley Wiltzer, Marc G. Bellemare, David Meger +2
When decisions are made at high frequency, traditional reinforcement learning (RL) methods struggle to accurately estimate action values. In turn, their performance is inconsistent…
Regularity Properties of Monotone Measure-preserving Maps
Alessio Figalli, Yash Jhaveri
In this note, we extend the regularity theory for monotone measure-preserving maps, also known as optimal transports for the quadratic cost optimal transport problem, to the case w…
On the Regularity of Optimal Transports between Degenerate Densities
Yash Jhaveri, Ovidiu Savin
We study the most common image and informal description of the optimal transport problem for quadratic cost, also known as the second boundary value problem for the Monge--Ampère e…
On the singular set in the thin obstacle problem: higher order blow-ups and the very thin obstacle problem
Xavier Fernández-Real, Yash Jhaveri
In this work, we consider the singular set in the thin obstacle problem with weight for , which arises as the local extension of the obstacle problem fo…
The obstacle problem for a fractional Monge--Ampère equation
Y. Jhaveri, P. R. Stinga
We study the obstacle problem for a nonlocal, degenerate elliptic Monge--Ampère equation. We show existence and regularity of a unique classical solution to the problem and regular…
On the (In)stability of the Identity Map in Optimal Transportation
Yash Jhaveri
We collect some examples of optimal transports in order to explore the (in)stability of the identity map as an optimal transport. First, we consider density and domain perturbation…
Partial Regularity of Solutions to the Second Boundary Value Problem for Generated Jacobian Equations
Yash Jhaveri
We prove that outside of a closed singular set of measure zero solutions to the second boundary value problem for generated Jacobian equations are smooth.
Higher Regularity of the Free Boundary in the Obstacle Problem for the Fractional Laplacian
Yash Jhaveri, Robin Neumayer
We prove a higher regularity result for the free boundary in the obstacle problem for the fractional Laplacian via a higher order boundary Harnack inequality.
Lipschitz Changes of Variables between Perturbations of Log-concave Measures
Maria Colombo, Alessio Figalli, Yash Jhaveri
Extending a result of Caffarelli, we provide global Lipschitz changes of variables between compactly supported perturbations of log-concave measures. The result is based on a combi…
Nonlinear Bounds in Hölder Spaces for the Monge-Ampère Equation
Alessio Figalli, Yash Jhaveri, Connor Mooney
We demonstrate that estimates for the Monge-Ampère equation depend in a highly nonlinear way both on the norm of the right-hand side and . First, we show that…
