P2DNav framework enhances zero-shot vision-language navigation

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced P2DNav, a new hierarchical framework designed to improve zero-shot vision-and-language navigation for embodied agents. This system decomposes navigation into two distinct stages: selecting a direction from a panoramic view and then grounding the instruction within that direction using a downview image. P2DNav also incorporates a sliding-window dialogue memory to manage navigation history and a reflective reorientation mechanism to assess grounding reliability, enhancing decision-making in unseen environments.

    P2DNav: Panorama-to-Downview Reasoning for Zero-shot Vision-and-Language Navigation

    Vision-and-language navigation (VLN) requires an embodied agent to ground natural-language instructions into executable navigation actions in unseen environments. Existing zero-shot methods typically rely on additional waypoint prediction modules, which often entangle high-level …
