Robust Vision-Language Navigation with Awareness of Instruction-Execution Progress

Read the original on arXiv Computer Vision →

The paper introduces VLN-AIEP, a Vision‑Language Navigation framework that integrates instruction‑execution progress awareness into navigation decisions. By linking the visited trajectory to the instruction, it suppresses embeddings of already executed content and matches candidate locations with pending instruction segments. The method employs a landmark‑anchored trajectory representation to encode semantic labels and geometry, enabling progress estimation without explicit supervision and achieving strong results on R2R, RxR, CVDN, and R2R‑CE benchmarks.

What do VLM-Based Vision-Language Navigation Models Rely on: Interpreting and Steering Policy Behavior

arXiv:2609.24576v1 Announce Type: cross Abstract: Modern Vision-Language Navigation (VLN) models rely mostly on pre-trained large Vision-Language Models (VLMs) to predict navigation actions. While th...

AVERT-VLN: Abstention-aware Visual Error Recovery and Training for Vision-and-Language Navigation

AVERT-VLN introduces a closed‑loop framework for vision‑and‑language navigation that incorporates an abstention‑aware Monitor to detect instruction‑execution inconsistencies. The Monitor is trained on a new LOSTNAV dataset of 20K counterfactual risk trajectories and fine‑tuned on 40K normal trajectories to recognize semantic deviations. During deployment, the Monitor can suspend autonomous navigation and request human guidance, while offline preference learning uses deviation‑associated failures to improve the policy, achieving 76.2% and 66.3% success on R2R‑CE and RxR‑CE unseen splits.

Path-level Hindsight Instructions for Semantic Exploration in Vision-Language Navigation

On-policy exploration is a crucial component for training robust Vision-Language Navigation agents, as it exposes the policy to a broader state distribution. However, such exploration inevitably leads to trajectories that deviate from expert demonstrations, resulting in a semantic mismatch between the executed visual stream and the original language instruction.
