### Model Summary
CLIP_TROHN-Img is a model presented in the [BiVLC](https://github.com/IMirandaM/BiVLC) paper for experimentation. It has been fine-tuned with OpenCLIP framework using as basis the CLIP ViT-B-32 model pre-trained by 'openai'. The idea behind this fine-tuning is to improve the compositional understanding of the model by adding negative pairs, i.e., negative captions and negative images. The negatives present small compositional changes. Hyperparameters:
* Learning rate: 1e-6.
* Scheduler: Cosine scheduler with 50 warmup steps.
* Optimizer: AdamW optimizer with beta1 = 0.9, beta2 = 0.98, eps = 1e-6 and weight decay = 0.1.
* Loss function: InfoNCE Loss.
* Batch size: We define a batch size of 200, and then we add negatives. It results in 400 images x 400 captions (200 positive + 200 hard negatives).
* Epochs: We fine-tune all models over 10 epochs and we used validation accuracy as the model selection criterion, i.e. we selected the model with the highest accuracy on the corresponding validation set.
* Data: It is fine-tuned with [TROHN-Img](https://huggingface.co/datasets/imirandam/TROHN-Img) dataset.
### Evaluation Data
