BiGym 2.0: Benchmarking Learned and Agent-Developed Policies for Humanoid Household Manipulation

Zexi Zhang, Zecheng Zhu, Zidong Chen وآخرون · 2026

Humanoid household manipulation requires the arms to act while the body balances, steps and changes posture. We present BiGym 2.0, an adaptation of BiGym for the Unitree G1 across 20 household tasks using a unified whole-body controller for demonstration and evaluation. The suite provides 60 native human virtual-realit …

UGOD: Uncertainty-Guided Opacity and Dropout for Sparse-View 3D Gaussian Splatting

Zhihao Guo, Peng Wang, Zidong Chen وآخرون · 2026

Sparse-view 3D Gaussian Splatting is prone to overfitting because limited observations leave many Gaussian primitives weakly constrained, yet their contributions are still accumulated through alpha blending. Without uncertainty estimation, the renderer cannot distinguish unreliable primitives from well-constrained ones …
