ActiveVLN: Towards Active Exploration Via Multi-Turn RL in Vision-And-Language Navigation
ICRA 2026poster
The Vision-and-Language Navigation (VLN) task requires an agent to follow natural language instructions and navigate through complex environments. Existing MLLM-based VLN methods primarily rely on imitation learning (IL) and often use DAgger for post-training to mitigate covariate shift. While effec…
