Translating Flow to Policy via Hindsight Online Imitation

Yitian Zheng, Zhangchen Ye, Weijun Dong, Shengjie Wang, Yuyang Liu, Chongjie Zhang +2

ICLR 2026poster

Recent advances in hierarchical robot systems leverage a high-level planner to propose task plans and a low-level policy to generate robot actions. This design allows training the planner on action-free or even non-robot data sources (e.g., videos), providing transferable high-level guidance. Nevert…

CVT-Occ: Cost Volume Temporal Fusion for 3D Occupancy Prediction

Zhangchen Ye, Tao Jiang, Chenfeng Xu, Yiming Li, Hang Zhao*

ECCV 2024poster

"Vision-based 3D occupancy prediction is significantly challenged by the inherent limitations of monocular vision in depth estimation. This paper introduces CVT-Occ, a novel approach that leverages temporal fusion through the geometric correspondence of voxels over time to improve the accuracy of 3D…
