Infinite Horizon Mean-Field Terminal Value Problem
Uğur Aydın, Tamer Başar, Naci Saldi
We introduce a class of finite- and infinite-horizon discrete-time control problems for studying macroscale systems in discrete time, which we refer to as mean-field terminal value…
Conditioning Degenerate Diffusion Models
Uğur Aydın, Tamer Başar
Current conditioned generative models heavily rely on score functions for guidance during training. When the generative model is a diffusion process with a singular diffusion coeff…
Independent Reinforcement Learning in Discounted Markov Games
Asrin Efe Yorulmaz, Ugur Aydin, Tamer Basar
In this work, we study radically uncoupled learning in discounted general-sum Markov games. Assuming `` for ", we show that, for every fixed discount f…
Horizon-Independent Contraction for Continuous-Time Discounted Regularized Mean-Field Games
Junji Yan, Uğur Aydın, Tamer Başar
We study contraction properties of non-stationary continuous-time mean-field games (MFGs) under discounting and entropy regularization. The state of the representative agent evolve…
Monotone Inclusion Approach to Weakly Monotone Discrete-Time Finite-Horizon Mean-Field Games
Uğur Aydın, Tamer Başar, Naci Saldi
We revisit the problem of computing mean-field equilibria (MFEs) in discrete-time, monotone, finite-horizon mean-field games (MFGs). We show that, when the transition kernel is ind…
Variational Contraction Conditions for Iterative Algorithms in Multi-Population Discrete-Time Regularized Mean-Field Games
Uğur Aydın, Tamer Başar
In this work, we study the contraction conditions of iterative algorithms for stationary and finite-horizon discrete-time regularized mean-field games (MFGs) with multiple populati…
Approximation of Discrete-Time Infinite-Horizon Mean-Field Equilibria via Finite-Horizon Mean-Field Equilibria
Uğur Aydın, Tamer Başar, Naci Saldi
We address in this paper a fundamental question that arises in mean-field games (MFGs), namely whether mean-field equilibria (MFE) for discrete-time finite-horizon MFGs can be used…
Robustness and Approximation of Discrete-time Mean-field Games under Discounted Cost Criterion
Uğur Aydın, Naci Saldi
In this paper, we investigate the robustness of stationary mean-field equilibria in the presence of model uncertainties, specifically focusing on infinite-horizon discounted cost f…
