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

Foresight-Guided Action Refinement (FGAR), which asymmetrically exploits proximal foresight for local action enhancement and route-critical foresight for feature-wise correction and route-level guidance, is introduced, validating the effectiveness of dual-horizon foresight and FGAR learning.

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.
