SPECTRA: Context-Conditioned Spectral Movement Primitives for Robot Skill Generalization
Boxuan Zhang, Sheng Liu, Chenlin Ming +1
The paper introduces Spectral Movement Primitives, a frequency‑domain approach that learns robot manipulation skills from demonstrations using low‑frequency Fourier coefficients an…
TRACES: Proactive Safety Auditing for Multi-Turn LLM Agents via Trajectory-State Modeling
Jiaqian Li, Yanshu Li, Boxuan Zhang +2
LLM agents increasingly operate through multi-turn tool use and environment interaction, where safety risks often emerge from intermediate steps long before they surface in the fin…
ClawGUI: A Unified Framework for Training, Evaluating, and Deploying GUI Agents
Fei Tang, Zhiqiong Lu, Boxuan Zhang +4
GUI agents drive applications through their visual interfaces instead of programmatic APIs, interacting with arbitrary software via taps, swipes, and keystrokes, reaching a long ta…
Shifting Uncertainty to Critical Moments: Towards Reliable Uncertainty Quantification for VLA Model
Yanchuan Tang, Taowen Wang, Yuefei Chen +3
Vision-Language-Action (VLA) models enable general-purpose robotic policies by mapping visual observations and language instructions to low-level actions, but they often lack relia…
Stochastic Trajectory Optimization for Robotic Skill Acquisition From a Suboptimal Demonstration
Chenlin Ming, Zitong Wang, Boxuan Zhang +3
Learning from Demonstration (LfD) has emerged as a crucial method for robots to acquire new skills. However, when given suboptimal task trajectory demonstrations with shape charact…
