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,

Personalization in Human-Robot Interaction Through Preference-Based Action Representation Learning

ICRA 2025

Preference- based reinforcement learning (PbRL) has shown significant promise for personalization in human- robot interaction (HRI) by explicitly integrating human preferences into the robot learning process. However, existing practices often require training a personalized robot policy from scratch

PrefMMT: Modeling Human Preferences in Preference-based Reinforcement Learning with Multimodal Transformers

IROS 2025

Preference-based reinforcement learning (PbRL) shows promise in aligning robot behaviors with human preferences, but its success depends heavily on the accurate modeling of human preferences through reward models. Most methods adopt Markovian assumptions for preference modeling (PM), which overlook
