Communication-Aware Robot Execution for Cloud Inference under Spatially Heterogeneous Connectivity

Fengkai Liu, Yuichi Ohsita, Masayuki Murata, Hideyuki Shimonishi

Cloud-hosted foundation models enable robots to use semantic reasoning beyond onboard computational limits. In this setting, the robot executes a currently available primitive generated by the cloud, and continued task progress requires the next cloud result before this primitive…

Exposure Bias Can Alleviate Itself via Directional and Frequency Rectification in Flow Matching

Guanbo Huang, Jingjia Mao, Fanding Huang, Fengkai Liu, Xiangyang Luo, Yaoyuan Liang, et al.

Flow Matching (FM) has achieved remarkable generative performance, yet it suffers from exposure bias due to discrepancies between training and inference. Existing mitigation strategies typically rely on static constraints or external heuristics. In this work, we propose that expo…
