Contrastive Visual Semantic Pretraining Magnifies the Semantics of Natural Language Representations (2022.acl-long)
Copied to clipboard
| Challenge: | Large-scale "natural language supervision" using image captions has enabled the first "zero-shot" AI image classifiers, which allow users to create their own image classes using natural language, yet outperform supervised models on common language-and-image tasks. |
| Approach: | They compare the geometry and semantic properties of contextualized English language representations formed by GPT-2 and CLIP, a zero-shot multimodal image classifier which adapts the GPT2 architecture to encode image captions. |
| Outcome: | The proposed classifier outperforms GPT-2 on word-level semantic intrinsic evaluation tasks and achieves a new corpus-based state of the art for the RG65 evaluation. |
