Minimum Coverage Sets for Training Robust Ad Hoc Teamwork Agents

no code implementations18 Aug 2023 Arrasy Rahman, Jiaxun Cui, Peter Stone

In this work, we first propose that maximizing an AHT agent's robustness requires it to emulate policies in the minimum coverage set (MCS), the set of best-response policies to any partner policies in the environment.

COOPERNAUT: End-to-End Driving with Cooperative Perception for Networked Vehicles

1 code implementation CVPR 2022 Jiaxun Cui, Hang Qiu, Dian Chen, Peter Stone, Yuke Zhu

To evaluate our model, we develop AutoCastSim, a network-augmented driving simulation framework with example accident-prone scenarios.

Learning a Robust Multiagent Driving Policy for Traffic Congestion Reduction

1 code implementation3 Dec 2021 Yulin Zhang, William Macke, Jiaxun Cui, Daniel Urieli, Peter Stone

This article establishes for the first time that a multiagent driving policy can be trained in such a way that it generalizes to different traffic flows, AV penetration, and road geometries, including on multi-lane roads.

Scalable Multiagent Driving Policies For Reducing Traffic Congestion

1 code implementation26 Feb 2021 Jiaxun Cui, William Macke, Harel Yedidsion, Daniel Urieli, Peter Stone

Next, we propose a modular transfer reinforcement learning approach, and use it to scale up a multiagent driving policy to outperform human-like traffic and existing approaches in a simulated realistic scenario, which is an order of magnitude larger than past scenarios (hundreds instead of tens of vehicles).
