Seeing Is Not Sharing: Some Vision-Language Models Overestimate Common Ground in Asymmetric Dialogue
TL;DR
Vision-language models often assume that both parties in a conversation share the same visual context, which can lead to misunderstandings. This study evaluates the performance of various vision-language models, including CLIP and BLIP, in asymmetric dialogue scenarios where one participant has access to visual information that the other does not.
✦ Why It Matters
Engineers can improve dialogue systems by addressing the limitations of vision-language models in asymmetric contexts.
Key Takeaways
- Test VLMs with diverse dialogue contexts to assess bias.
- Incorporate dynamic tracking of dialogue history in models.
- Use textual descriptions alongside images for better alignment.
- Be cautious of over-relying on visual cues for mutual understanding.
How It Works
The study formulates an interpretation-matching task to evaluate how VLMs distinguish between shared and potentially shared information. By manipulating dialogue context and access to map information, the researchers analyze model responses to various inputs, revealing biases in interpreting visual versus textual cues.
