Infinite-Dimensional Fisher Markets and Tractable Fair Division
Yuan Gao, Christian Kroer
Linear Fisher markets are a fundamental economic model with applications in fair division as well as large-scale Internet markets. In the finite-dimensional case of buyers and…
First-Order Methods for Wasserstein Distributionally Robust MDP
Julien Grand-Clément, Christian Kroer
Markov decision processes (MDPs) are known to be sensitive to parameter specification. Distributionally robust MDPs alleviate this issue by allowing for \emph{ambiguity sets} which…
Faster Game Solving via Predictive Blackwell Approachability: Connecting Regret Matching and Mirror Descent
Gabriele Farina, Christian Kroer, Tuomas Sandholm
Blackwell approachability is a framework for reasoning about repeated games with vector-valued payoffs. We introduce predictive Blackwell approachability, where an estimate of the…
Dominant Resource Fairness with Meta-Types
Steven Yin, Shatian Wang, Lingyi Zhang +1
Inspired by the recent COVID-19 pandemic, we study a generalization of the multi-resource allocation problem with heterogeneous demands and Leontief utilities. Unlike existing sett…
Evaluating and Rewarding Teamwork Using Cooperative Game Abstractions
Tom Yan, Christian Kroer, Alexander Peysakhovich
Can we predict how well a team of individuals will perform together? How should individuals be rewarded for their contributions to the team performance? Cooperative game theory giv…
First-Order Methods for Large-Scale Market Equilibrium Computation
Yuan Gao, Christian Kroer
Market equilibrium is a solution concept with many applications such as digital ad markets, fair division, and resource sharing. For many classes of utility functions, equilibria c…
