Disentangling Visuo-Tactile Foresight: Oracle-Guided Interface Discovery for World Action Models
Zihang Yao, Chaoyue Ding, Yingying Yu
Contact-rich manipulation remains challenging because successful control depends on physical interaction cues that are often weakly observable from vision alone. Recent tactile wor…
A memory-efficient deterministic method for multiscale gas flows using an ensemble-of-subproblems strategy with stochastic discrete velocities
Shuyang Zhang, Weidong Li, Ming Fang +1
Deterministic multiscale gas flow simulations have long suffered from the curse of dimensionality: the number of discrete velocities increases dramatically with the velocity space…
Mitigating ray effects in rarefied flow simulations using an ensemble-of-subproblems strategy with stochastic discrete velocities
Shuyang Zhang, Weidong Li, Ming Fang +1
In this work, a ensemble-of-subproblems strategy with stochastic discrete velocities is extended to deterministic methods for mitigating ray effects in rarefied flow simulations. T…
SAM3D-Guided Object-Centric Representation Alignment for Vision-Language-Action Models
Zonghe Liu, Shanyuan Jie, Xiaoquan Sun +4
Vision-Language-Action (VLA) models have shown strong potential for general robot manipulation, but most existing models rely on 2D visual-language backbones and lack fine-grained…
