HiTac-WAM: A Hierarchical Tactile World Action Model for Contact-Rich Robot Manipulation
Chao Xue, Chaofan Zhang, Wenxuan Ma +3
World action models jointly predict future visual observations and actions, whereas existing tactile-aware variants typically represent future touch as an image or latent stream wi…
Beyond Teacher Likelihood: Group-Calibrated On-Policy Distillation for Long-Context Reasoning
Zhu Zhang, Jixun Wang, Xiaoang Xu +6
On-policy distillation (OPD) trains a student on its own responses using dense token-level guidance from a stronger teacher. In long-context tasks, however, token-level teacher sup…
Large Field-Free Superconducting Diode Effect with Nonmonotonic Polarity Reversals in NbSe/CrBr Heterostructures
Shengbiao Sun, Lang Xiao, Chenghao Shen +10
The superconducting diode effect (SDE), characterized by nonreciprocal dissipationless supercurrent, offers a promising route toward ultralow-power superconducting electronics. Yet…
SLO-Scaler: Uncertainty-Aware SLO-Driven Autoscaling for Microservices
Shuo Wang, Xiaoxuan Sun, Shao-yu Huang +3
Autoscaling microservice-based applications to satisfy Service Level Objectives (SLOs) remains challenging due to bursty workloads, cascading latency across service dependencies, a…
