LIBERO-Dynamic: Benchmarking Robotic Manipulation in Dynamic Environments
Shaojie Ren, Jingwen Sun, Zezhi Liu +4
Most simulation benchmarks for robotic manipulation keep target objects static and treat policy inference as instantaneous. These assumptions simplify evaluation but hide how a mov…
Homogenization of an optimal control problem for a Navier-Stokes-Cahn-Hilliard system in a 3D perforated domain
Amartya Chakrabortty, Haradhan Dutta, Hari Shankar Mahato
We study the homogenization of an optimal control problem governed by a Navier-Stokes-Cahn-Hilliard system in a periodically perforated three-dimensional domain. The obstacles are…
VLA-JEPA: Enhancing Vision-Language-Action Model with Latent World Model
Jingwen Sun, Wenyao Zhang, Zekun Qi +6
Pretraining Vision-Language-Action (VLA) policies on internet-scale video is appealing, yet current latent-action objectives often learn the wrong thing: they remain anchored to pi…
Beyond a Single Queue: Multi-Level-Multi-Queue as an Effective Design for SSSP problems on GPUs
Zhengding Hu, Jingwen Sun, Le Jiang +4
As one of the most fundamental problems in graph processing, the Single-Source Shortest Path (SSSP) problem plays a critical role in numerous application scenarios. However, existi…
