Real-Time Coverage Path Planning for Bone-Aware Robotic Ultrasound Scanning

RA-L 2026

Robotic ultrasound systems offer significant potential for automated organ coverage scanning, yet acoustic shadows from bone structures can cause incomplete scans and missed diagnoses. This work presents a real-time coverage path planning method for bone-aware robotic ultrasound scanning. A voxel ba

Lost in the Context: Insufficient and Distracted Attention to Contexts in Preference Modeling

ACL 2025long

In Reinforcement Learning from Human Feedback (RLHF), the reward model (RM) evaluates the response quality based on the given context and assigns a reward. It plays a crucial role in aligning RLHF with human preferences. Although the current RM training paradigm concatenates the context and response…
