Paparazzi: A Deep Dive into the Capabilities of Language and Vision Models for Grounding Viewpoint Descriptions (2023.findings-eacl)
Copied to clipboard
| Challenge: | Existing language and vision models can be used for language understanding in 3D environments . however, existing models lack specific properties and biases that limit their performance . |
| Approach: | They propose a framework that uses a camera to generate images from different viewpoints and evaluate them in terms of their similarity to natural language descriptions. |
| Outcome: | The proposed model performs poorly on most canonical views and fine-tunes using hard negative sampling and random contrasting yields good results even under conditions with little available training data. |
