Adaptive Task Allocation in Multi-Human Multi-Robot Teams Under Team Heterogeneity and Dynamic Information Uncertainty

ICRA 2025

Task allocation in multi-human multi-robot (MHMR) teams presents significant challenges due to the inherent heterogeneity of team members, the dynamics of task execution, and the information uncertainty of operational states. Existing approaches often fail to address these challenges simultaneously,

PrefCLM: Enhancing Preference-Based Reinforcement Learning With Crowdsourced Large Language Models

RA-L 2025

Preference-based reinforcement learning (PbRL) is emerging as a promising approach to teaching robots through human comparative feedback without complex reward engineering. However, the substantial volume of human feedback required hinders broader applications. In this work, we introduce PrefCLM, a

Value Imprint: A Technique for Auditing the Human Values Embedded in RLHF Datasets

NeurIPS 2024spotlight

LLMs are increasingly fine-tuned using RLHF datasets to align them with human preferences and values. However, very limited research has investigated which specific human values are operationalized through these datasets. In this paper, we introduce Value Imprint, a framework for auditing and classi…
