Summary

This research introduces CE-CM, a Bayesian method for autonomous agents to infer task-invariant partner capabilities in multi-task ad-hoc teamwork, improving collaboration without prior training. An extension, CE-CM-Div, further enhances estimates by accounting for human behavioral diversity.

Autonomous agents often struggle to collaborate effectively with new and diverse partners, especially when partner capabilities are unknown and tasks are varied. This paper addresses these limitations by proposing a new approach called Capability Estimation via Contextual Models (CE-CM). This method allows agents to infer task-invariant capability vectors of partners through approximate Bayesian inference and simulation-based sampling. CE-CM reframes ad-hoc teamwork as a joint planning problem with decentralized execution under hidden partner capabilities, enabling online refinement of beliefs from minimal tasks. To account for the inherent unpredictability of human collaborators, an extension, CE-CM-Div, was developed. This variant evaluates capability hypotheses against diverse planner rollouts, rather than assuming optimal trajectories. Experiments show CE-CM rapidly recovers hidden capabilities and reduces infeasible action assignments, with CE-CM-Div significantly improving estimates in human studies, highlighting the importance of modeling behavioral diversity for robust human-AI teaming.

Why it matters

Professionals developing or deploying autonomous systems in collaborative environments can leverage this research to create more adaptable and robust AI agents that can effectively team with humans or other unknown agents.

How to implement this in your domain

  1. 1Explore integrating capability estimation modules into your autonomous agent designs for dynamic team environments.
  2. 2Consider using simulation-based sampling to infer partner capabilities in real-time for improved task allocation.
  3. 3Design agent systems that account for diverse human behaviors and sub-optimal actions, rather than assuming perfect rationality.
  4. 4Apply these principles to improve human-robot collaboration in manufacturing, logistics, or defense applications.

Dual Teachers Improve Adversarial Robustness and Accuracy.

This work extends Information Bottleneck Distillation (IBD) by introducing a "clean teacher" alongside a robust teacher to improve the robustness/accuracy tradeoff against adversarial attacks. The proposed method transfers features from both teachers to a student model, achieving better clean accuracy while maintaining adversarial robustness, outperforming original IBD and competing with state-of-the-art approaches.
