NavHint: Vision and Language Navigation Agent with a Hint Generator (2024.findings-eacl)
Copied to clipboard
| Challenge: | Existing work on vision and language navigation relies on navigation-related losses to establish the connection between vision and modalities, neglecting aspects of helping the navigation agent build a deep understanding of the visual environment. |
| Approach: | They propose to provide indirect supervision to the navigation agent through a hint generator that generates visual descriptions during navigation. |
| Outcome: | The proposed method improves the navigation performance and interpretability of the R2R and R4R datasets. |
