# Model card for kat_small_patch16_224.vitft

KAT model trained on ImageNet-1k (1 million images, 1,000 classes) at resolution 224x224. It was first introduced in the paper Kolmogorov–Arnold Transformer.

## Model description
KAT is a model that replaces channel mixer in transfomrers with Group Rational Kolmogorov–Arnold Network (GR-KAN).

## Usage
The model definition is at https://github.com/Adamdad/kat, `katransformer.py`. 

```python
from urllib.request import urlopen
from PIL import Image
import timm
import torch
import katransformer

img = Image.open(urlopen(
    'https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/beignets-task-guide.png'
))

# Move model to CUDA
device = torch.device('cuda' if torch.cuda.is_available() else 'cpu')

model = timm.create_model("hf_hub:adamdad/kat_small_patch16_224.vitft", pretrained=True)
model = model.to(device)
model = model.eval()



# get model specific transforms (normalization, resize)
data_config = timm.data.resolve_model_data_config(model)
transforms = timm.data.create_transform(**data_config, is_training=False)

output = model(transforms(img).unsqueeze(0).to(device))  # unsqueeze single image into batch of 1

top5_probabilities, top5_class_indices = torch.topk(output.softmax(dim=1) * 100, k=5)
print(top5_probabilities)
print(top5_class_indices)

```
