ForeFly: A Dual-Horizon World Action Model for Aerial Vision-Language Navigation

Aerial Vision-Language Navigation (AVLN) requires UAVs to maintain reliable instruction following over long trajectories in complex 3D environments. However, existing AVLN approaches are predominantly reactive or limited to single-horizon prediction, overlooking complementary future cues across different temporal horiz...

Towards a Causally-inspired Evolving World Model for Vision-and-Language Navigation in Continuous Environments.

A causally-inspired evolving world modeling framework that formulates VLN-CE as a sequence of causal partially observable Markov decision processes that learns unified latent states that integrate vision, language, and action, and strengthens generalization across diverse navigation contexts.
