Robo-ValueRL: Reliable Value Estimation for Offline-to-Online Reinforcement Learning

Wenke Xia, Pei Ren, Wenbo Yu, Yizhuo Zhang, Jifan Li, Yixue Zhang, et al.

Offline-to-online reinforcement learning is promising for generalizable robotic manipulation, yet its full-stack complexity obscures reproduction and diagnosis. Within such systems, value estimation plays a central role in prioritizing heterogeneous data for policy improvement. D…

Spatial Attention: Adapting Execution Horizons for Diffusion Policies via Observation Sensitivity

Che-Sang Park, Junsu Ha, Jianlong Fu, Frank C. Park

Sampling action chunks via generative models has become a widely adopted methodology for robotic learning from demonstration. However, existing methods often struggle to balance responsiveness and computational cost because they execute each action chunk for a fixed execution hor…
