Overview

To empower human activities and transform our lives, robots need to be deployed in environments shared by other intelligent decision makers. For instance, autonomous vehicles need to share roads with pedestrians, human-driven cars, and autonomous cars. Autonomous delivery drones need to navigate in airspace shared by other aircraft, and mobile robots in a warehouse must navigate factory floors shared by other robots as well as humans. To act appropriately in these complex scenarios, robots need to be capable of interacting strategically with other agents, which in turn requires us to develop interaction-aware, strategic learning and decision-making algorithms.

In this workshop, we study learning and optimal decision making in such strategic, multi-agent contexts. Although the game theoretical foundations of multi-agent strategic interactions are well-established, we aim to bring together expert researchers and practitioners with new and diverse experience and perspectives in the nascent field of game-theoretic decision making. In particular, we hope that workshop attendees will:

Gain a deeper technical understanding of the mathematical foundations of multi-agent games and a familiarity with modern algorithmic solution methods.
Engage in frank and illuminating discussions regarding the role of game-theoretic methods in robot learning
Be exposed to technical viewpoints from both within and outside the robotics community on challenging aspects of game-theoretic decision making, including:

High-dimensional, continuous state and action spaces
Partial observability
The subtle role of information structure
Algorithmic scalability

Areas of interest: Modeling multi-agent uncertainty, theory of mind, robust decision-making in dynamic environments, partial observability in multi-agent decision-making, etc.

Techniques include: game theory, optimization, optimal control, robust control, probability theory, bayesian inference, POMDPs, etc.
