### Model Card: clip-imageclef

### Model Details

[OpenAI CLIP model](https://openai.com/blog/clip/) fine-tuned using image-caption pairs from the [Caption Prediction dataset](https://www.imageclef.org/2017/caption) provided for the ImageCLEF 2017 competition. The model was evaluated using before and after fine-tuning, MRR@10 were 0.57 and 0.88 respectively.

### Model Date

September 6, 2021

### Model Type

The base model is the OpenAI CLIP model. It uses a ViT-B/32 Transformer architecture as an image encoder and uses a masked self-attention Transformer as a text encoder. These encoders are trained to maximize the similarity of (image, text) pairs via a contrastive loss.

### Fine-tuning

The fine-tuning can be reproduced using code from the Github repository [elsevierlabs-os/clip-image-search](https://github.com/elsevierlabs-os/clip-image-search#fine-tuning).

### Usage

```python
from transformers import CLIPModel, CLIPProcessor

model = CLIPModel.from_pretrained("sujitpal/clip-imageclef")
processor = CLIPModel.from_pretrained("openai/clip-vit-base-patch32")
inputs = processor(text=captions, images=images, 
                   return_tensors="pt", padding=True)
output = model(**inputs)
```

### Performance

| Model-name                       | k=1   | k=3   | k=5   | k=10  | k=20  |
