Robust perceptual metric, based on CLIP model `laion/CLIP-convnext_base_w-laion2B-s13B-b82K-augreg`

Adversarially fine-tuned with FARE ([Schlarmann et al. (2024)](https://arxiv.org/abs/2402.12336)) on ImageNet with infinity-norm and radius 4/255.

Performance on the perceptual similarity task [NIGHTS](https://dreamsim-nights.github.io):
```
Clean     L-inf, eps=4/255     L2, eps=3
90.6      74.3                 66.1
```

## Usage
```python
model, _, image_processor = open_clip.create_model_and_transforms('hf-hub:chs20/FARE4-convnext_base_w-laion2B-s13B-b82K-augreg')
```
