Learning and Covering Sums of Independent Random Variables with Unbounded Support

Alkis Kalavasis, Konstantinos Stavropoulos, Manolis Zampetakis

We study the problem of covering and learning sums of independent integer-valued random variables (SIIRVs) with unbounded, or even infinite, support.…

STay-ON-the-Ridge: Guaranteed Convergence to Local Minimax Equilibrium in Nonconvex-Nonconcave Games

Constantinos Daskalakis, Noah Golowich, Stratis Skoulakis +1

Min-max optimization problems involving nonconvex-nonconcave objectives have found important applications in adversarial training and other multi-agent learning settings. Yet, no k…

On the Complexity of Deterministic Nonsmooth and Nonconvex Optimization

Michael I. Jordan, Tianyi Lin, Manolis Zampetakis

In this paper, we present several new results on minimizing a nonsmooth and nonconvex function under a Lipschitz condition. Recent work shows that while the classical notion of Cla…

The Computational Complexity of Multi-player Concave Games and Kakutani Fixed Points

Christos H. Papadimitriou, Emmanouil-Vasileios Vlatakis-Gkaragkounis, Manolis Zampetakis

Kakutani's Fixed Point theorem is a fundamental theorem in topology with numerous applications in game theory and economics. Computational formulations of Kakutani exist only in sp…

Estimation of Standard Auction Models

Yeshwanth Cherapanamjeri, Constantinos Daskalakis, Andrew Ilyas +1

We provide efficient estimation methods for first- and second-price auctions under independent (asymmetric) private values and partial observability. Given a finite set of observat…

What Makes A Good Fisherman? Linear Regression under Self-Selection Bias

Yeshwanth Cherapanamjeri, Constantinos Daskalakis, Andrew Ilyas +1

In the classical setting of self-selection, the goal is to learn models, simultaneously from observations where is the output of one of under…

First-Order Algorithms for Nonlinear Generalized Nash Equilibrium Problems

Michael I. Jordan, Tianyi Lin, Manolis Zampetakis

We consider the problem of computing an equilibrium in a class of \textit{nonlinear generalized Nash equilibrium problems (NGNEPs)} in which the strategy sets for each player are d…
