• Abstract: Mutual adaptation is a central challenge in human--AI teaming, as humans naturally adjust their strategies in response to a robot's policy. Existing approaches aim to improve diversity in training partners to approximate human behavior, but these partners are static and fail to capture adaptive behavior of humans. Exposing robots to adaptive behaviors is critical, yet when both agents learn simultaneously in a multi-agent setting, they often converge to opaque implicit coordination strategies that only work with the agents they were co-trained with. Such agents fail to generalize when paired with new partners. In order to capture the adaptive behavior of humans, we model the human-robot teaming scenario as an Interactive Partially Observable Markov Decision Process (I-POMDP), explicitly modeling human adaptation as part of the state. We propose a nested training regime to approximately learn the solution to a finite-level I-POMDP. In this framework, agents at each level are trained against adaptive agents from the level below. This ensures that the ego agent is exposed to adaptive behavior during training while avoiding the emergence of implicit coordination strategies, since the training partners are not themselves learning. We train our method in a multi-episode, required cooperation setup in the Overcooked domain, comparing it against several baseline agents designed for human-robot teaming. We evaluate the performance of our agent when paired with adaptive partners that were not seen during training. Our results demonstrate that our agent not only achieves higher task performance with these adaptive partners but also exhibits significantly greater adaptability during team interactions.

  We focus on influence in settings where there is a need to capture human suboptimality. Experiments online with humans is potentially unsafe, and creating a high-fidelity simulator of the environment is often impractical. We show that offline reinforcement learning can learn to effectively influence suboptimal humans by extending and combining elements of observed human-human behavior.

  We propose a policy ensemble method to increase the diversity of partners in the population.

In this way, the ego agent is able to learn more universal cooperative behaviors for collaborating with diverse partners.

  In multiagent competitive scenarios, ego-agents may have to adapt to new opponents with previously unseen behaviors. As the ego-agent updates its own behavior to exploit the opponent, its own behavior could become more exploitable. We develop a safe adaptation approach in which the ego-agent is trained against a regularized opponent model.

  In various real-world tasks, an agent needs to cooperate with unknown partner agent types. Deep reinforcement learning models can be trained to deliver the required functionality but are known to suffer from sample inefficiency and slow learning. We suggest a method, where we synthetically produce populations of agents with different behavioural patterns together with ground truth data of their behaviour. We additionally suggest an agent architecture, which can efficiently use the generated data and gain the meta-learning capability.
