Relaxing Relationship Queries on Graph Data

1 code implementation24 Feb 2020 Shuxin Li, Gong Cheng, Chengkai Li

We prove that verifying the success of a sub-query turns into finding an entity (called a certificate) that satisfies a distance-based condition about the query entities.

Offline Equilibrium Finding

no code implementations2 Jul 2019 Xiaxia Wang, Jinchi Chen, Shuxin Li, Gong Cheng, Jeff Z. Pan, Evgeny Kharlamov, Yuzhong Qu

Reusing existing datasets is of considerable significance to researchers and developers.

CFR-MIX: Solving Imperfect Information Extensive-Form Games with Combinatorial Action Space

no code implementations18 May 2021 Shuxin Li, Youzhi Zhang, Xinrun Wang, Wanqi Xue, Bo An

The challenge of solving this type of game is that the team's joint action space grows exponentially with the number of agents, which results in the inefficiency of the existing algorithms, e. g., Counterfactual Regret Minimization (CFR).

Population-size-Aware Policy Optimization for Mean-Field Games

no code implementations7 Feb 2023 Pengdeng Li, Xinrun Wang, Shuxin Li, Hau Chan, Bo An

In this work, we attempt to bridge the two fields of finite-agent and infinite-agent games, by studying how the optimal policies of agents evolve with the number of agents (population size) in mean-field games, an agent-centric perspective in contrast to the existing works focusing typically on the convergence of the empirical distribution of the population.
