InternVLA-A1.5: Unifying Understanding, Latent Foresight, and Action for Compositional Generalization

Haoxiang Ma, Junhao Cai, Xiaoxu Xu +26

Unified models for robot manipulation aim to equip one policy with both the semantic priors of pretrained VLMs and the physical dynamics learned through future prediction. In pract…

FutureVLA: Joint Visuomotor Prediction for Vision-Language-Action Model

Xiaoxu Xu, Hao Li, Jinhui Ye +7

Predictive foresight is important to intelligent embodied agents. Since the motor execution of a robot is intrinsically constrained by its visual perception of environmental geomet…

Weakly-Supervised 3D Visual Grounding based on Visual Language Alignment

Xiaoxu Xu, Yitian Yuan, Qiudan Zhang +4

Learning to ground natural language queries to target objects or regions in 3D point clouds is quite essential for 3D scene understanding. Nevertheless, existing 3D visual groundin…

LESS: Label-Efficient and Single-Stage Referring 3D Segmentation

Xuexun Liu, Xiaoxu Xu, Jinlong Li +4

Referring 3D Segmentation is a visual-language task that segments all points of the specified object from a 3D point cloud described by a sentence of query. Previous works perform…
