Look-ahead Search on Top of Policy Networks in Imperfect Information Games

IJCAI 2024poster

Search in test time is often used to improve the performance of reinforcement learning algorithms. Performing theoretically sound search in fully adversarial two-player games with imperfect information is notoriously difficult and requires a complicated training process. We present a method for addi…

Rethinking Formal Models of Partially Observable Multiagent Decision Making (Extended Abstract)

IJCAI 2023poster

Multiagent decision-making in partially observable environments is usually modelled as either an extensive-form game (EFG) in game theory or a partially observable stochastic game (POSG) in multiagent reinforcement learning (MARL). One issue with the current situation is that while most practical pr…

Approximate Exploitability: Learning a Best Response

IJCAI 2022poster

Researchers have shown that neural networks are vulnerable to adversarial examples and subtle environment changes. The resulting errors can look like blunders to humans, eroding trust in these agents. In prior games research, agent evaluation often focused on the in-practice game outcomes. Such eva…

From Poincaré Recurrence to Convergence in Imperfect Information Games: Finding Equilibrium via Regularization

ICML 2021spotlight

In this paper we investigate the Follow the Regularized Leader dynamics in sequential imperfect information games (IIG). We generalize existing results of Poincar{é} recurrence from normal-form games to zero-sum two-player imperfect information games and other sequential game settings. We then inves…

Solving Common-Payoff Games with Approximate Policy Iteration

AAAI 2021technical

For artificially intelligent learning systems to have widespread applicability in real-world settings, it is important that they be able to operate decentrally. Unfortunately, decentralized control is difficult---computing even an epsilon-optimal joint policy is a NEXP complete problem. Nevertheless…

Bayesian Action Decoder for Deep Multi-Agent Reinforcement Learning

ICML 2019oral

When observing the actions of others, humans make inferences about why they acted as they did, and what this implies about the world; humans also use the fact that their actions will be interpreted in this manner, allowing them to act informatively and thereby communicate efficiently with others. Al…
