Relational Geometry Forcing for World Action Models

Yuan Xu, Yixiang Chen, Qisen Ma +10

World Action Models (WAMs) have shown strong potential for robot manipulation by jointly learning visual dynamics and executable actions. However, their video and action objectives…

GuardianBench: A Same-Scene Instruction-Contrastive Benchmark for Latent Contextual Risk in Embodied AI

Zhesheng Zhang, Jiahao Lu, Wei Liu +8

In embodied AI, safety risk can be latent: a benign instruction and a safe scene become hazardous only when composed. Prior work has advanced embodied safety by varying visual cont…

Actor and Action Modular Network for Text-based Video Segmentation

Jianhua Yang, Yan Huang, Kai Niu +3

Text-based video segmentation aims to segment an actor in video sequences by specifying the actor and its performing action with a textual query. Previous methods fail to explicitl…
