Social herding in mean field games

no code implementations6 Mar 2023 Deepanshu Vasal

In this paper, we consider a mean field model of social behavior where there are an infinite number of players, each of whom observes a type privately that represents her preference, and publicly observes a mean field state of types and actions of the players in the society.

Mean field teams and games with correlated types

no code implementations20 Oct 2022 Deepanshu Vasal

In this paper, we introduce a new model of mean field teams and games with \emph{correlated types} where there are a large population of homogeneous players sequentially making strategic decisions and each player is affected by other players through an aggregate population state.

Master equation of discrete-time Stackelberg mean field games with multiple leaders

no code implementations7 Sep 2022 Deepanshu Vasal

In this paper, we consider a discrete-time Stackelberg graphon mean field game with a finite number of leaders, a finite number of major followers and an infinite number of minor followers.

Master Equation for Discrete-Time Stackelberg Mean Field Games with single leader

no code implementations16 Jan 2022 Deepanshu Vasal, Randall Berry

First, we consider an epidemic model where the followers get infected based on the mean field population.

Convergence of Generalized Belief Propagation Algorithm on Graphs with Motifs

no code implementations11 Dec 2021 Yitao Chen, Deepanshu Vasal

Belief propagation is a fundamental message-passing algorithm for numerous applications in machine learning.

Multi-Agent Decentralized Belief Propagation on Graphs

no code implementations6 Nov 2020 Yitao Chen, Deepanshu Vasal

We consider the problem of interactive partially observable Markov decision processes (I-POMDPs), where the agents are located at the nodes of a communication network.

Model-free Reinforcement Learning for Stochastic Stackelberg Security Games

no code implementations24 May 2020 Deepanshu Vasal

In such a scenario, the leader has the advantage of committing to a policy which maximizes its own returns given the knowledge that the follower is going to play the best response to its policy.

Fault Tolerant Equilibria in Anonymous Games: best response correspondences and fixed points

no code implementations14 May 2020 Deepanshu Vasal, Randall Berry

A Nash equilibrium in a game with $N$ players is said to be $\alpha$-tolerant if no non-faulty user wants to deviate from an equilibrium strategy as long as $N-\alpha-1$ other players are playing the equilibrium strategies, i. e., it is robust to deviations from rationality by $\alpha$ faulty players.

Mechanism Design for Large Scale Network Utility Maximization

no code implementations9 Mar 2020 Meng Zhang, Deepanshu Vasal

With infinitely many agents, agents' truthful reports of their types are their dominant strategies; for the finite case, each agent's incentive to misreport converges quadratically to zero.
