NavCMPO: Critic-Guided MeanFlow Policy Optimization for Adaptive Navigation

Junjie An, Yi Wu, Xiao Liu, Yiqun Zhou, Yuechen Wu, Xiaoqing Guan, et al.

End-to-end diffusion-based policies have demonstrated strong performance in mapless visual navigation, but their iterative denoising process introduces substantial inference latency, while behavior cloning limits performance to the quality of expert demonstrations. We present Nav…

SoftNav: Injecting 3D Scene Tokens into VLMs for Embodied Navigation

Yi Wu, Junjie An, Xiao Liu, Yiqun Zhou, Yuechen Wu, Xiaoqing Guan, et al.

In goal-directed embodied navigation, where an agent must locate a specified target in an unseen environment, 3D scene understanding and navigation reasoning must work in concert. Current approaches transmit 3D scene information to vision-language models (VLMs) through text, sugg…
