Synchronizing Beliefs with Second-Order Theory-of-Mind in Human-Autonomy Teams (Extended Version)

arXiv cs.AI ↗ · 2026-08-13 Cached

This paper recasts preference-based reward learning as a human-autonomy team problem, arguing that a teacher who knows the objective can design more efficient training examples than learner-driven query selection. It introduces understanding statements with second-order theory-of-mind to keep the teacher's model of the learner synchronized, showing in simulation that this approach outperforms learner-led selection.

Learning Safe Agent Behaviour from Human Preferences and Justifications via World Models

arXiv cs.AI ↗ · 2026-07-16 Cached

This paper introduces DROPJ, a human-centred method for safely training and deploying agent policies by learning a world model from real-world trajectories, then eliciting human preferences with justifications to train a reward model for model predictive control. Experiments show that using human-generated simulated trajectories and justifications improves safety and reduces computational cost.

Internal Pluralism and the Limits of Pairwise Comparisons

arXiv cs.AI ↗ · 2026-07-07 Cached

This paper critiques the use of pairwise comparisons for learning human preferences, arguing that internal pluralism (multiple conflicting priorities) undermines the standard approach. It proposes a formal model and suggests that allowing indecision can improve learning efficiency.
