• Abstract: Being able to cooperate with new people is an important component of many economically valuable AI tasks, from household robotics to autonomous driving. However, generalizing to novel humans requires training on data that captures the diversity of human behaviors. Adversarial training is one avenue for searching for such data and ensuring that agents are robust. However, it is difficult to apply in the cooperative setting because adversarial policies intentionally learn to sabotage the task instead of simulating valid cooperation partners. To address this challenge, we propose a novel strategy for overcoming self-sabotage that combines a pre-trained generative model to simulate valid cooperative agent policies with adversarial training to maximize regret. We call our method GOAT: Generative Online Adversarial Training. In this framework, the GOAT dynamically searches for and generates coordination strategies where the learning policy -- the Cooperator agent -- underperforms. GOAT enables better generalization by exposing the Cooperator to various challenging interaction scenarios. We maintain realistic coordination strategies by updating only the generative model's embedding while keeping its parameters frozen, thus avoiding adversarial exploitation. We evaluate GOAT with real human partners, and the results demonstrate state-of-the-art performance on the Overcooked benchmark, highlighting its effectiveness in generalizing to diverse human behaviors.

  Training agents that can coordinate zero-shot with humans is a key mission in multi-agent reinforcement learning (MARL) We show emphlearning a generative model of human partners can effectively address this issue. By sampling from the latent space, we can use the generative model to produce different partners to train Cooperator agents.

  Existing methods for human-AI coordination typically train an agent to coordinate with a diverse set of policies or with human models fitted from real human data. We propose employing the large language model (LLM) to develop an action plan that effectively guides both human and AI. Our method achieves better alignment with human preferences and an average performance improvement of 15% compared to the state-of-the-art.

  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.
