 In experiment 4, we look at the performance of models based on [Contrastive Language-Image Pretraining](https://arxiv.org/pdf/2103.00020.pdf) (CLIP). CLIP models employ separate but jointly trained Text and Image encoders to create a single multimodal embedding space. Regardless of whether the embeddings in this space represent text or image, if they are semantically similar, they are positioned closer together.

 The structure of CLIP encoders (image above) makes them versatile and adaptable to various model architectures for embedding text or image data. In our experiment, we used pretrained models from the [OpenClip leaderboard](https://github.com/mlfoundations/open_clip/blob/main/docs/openclip_results.csv), and applied the Image Encoder to embed the images. Then we evaluated the outcomes.
