JaxAHT library released to speed up ad hoc teamwork research

A new arXiv paper introduces JaxAHT, a JAX-based library aimed at ad hoc teamwork, where agents must coordinate with unfamiliar partners without prior arrangements. The authors argue that the field's progress is slowed by the heavy computational cost of typical AHT experiments, and the library is intended to reduce that burden. It is presented as a research tool rather than a product release.

ROTATE: Regret-driven Open-ended Training for Ad Hoc Teamwork

A new arXiv paper presents ROTATE, a training method designed to help agents cooperate effectively with partners they have never seen before, a problem known as ad hoc teamwork. Rather than relying on a pre-built, fixed set of teammate agents followed by a separate coordination stage, the approach uses regret signals to continuously steer the creation of training collaborators. The work addresses generalization in multi-agent reinforcement learning.
