# vit-artworkclassifier
This model returns the artwork style of any image input.


This model is a fine-tuned version of [google/vit-base-patch16-224-in21k](https://huggingface.co/google/vit-base-patch16-224-in21k) on the imagefolder dataset. This is a subset of the artbench-10 dataset (https://www.kaggle.com/datasets/alexanderliao/artbench10), with a train set of 1000 artworks per class and a validation set of 100 artworks per class.
It achieves the following results on the evaluation set:
- Loss: 1.1392
- Accuracy: 0.5948

## Model description

You can find a description of the project that this model was trained for here: https://medium.com/@oliverpj.schamp/training-and-evaluating-stable-diffusion-for-artwork-generation-b099d1f5b7a6

## Intended uses & limitations

This model only contains 9 out of the 10 artbench-10 classes - it does not contain ukiyo_e. This was due to availability and formatting issues.

## Training and evaluation data

Train: 1000 randomly selected images from artbench-10 (per class). Val: 100 randomly selected images from artbench-10 (per class).

### Code to Run
```
def vit_classify(image):
    vit = ViTForImageClassification.from_pretrained("oschamp/vit-artworkclassifier")
    vit.eval()
    device = torch.device('cuda' if torch.cuda.is_available() else 'cpu')
    vit.to(device)
    
    model_name_or_path = 'google/vit-base-patch16-224-in21k'
    feature_extractor = ViTFeatureExtractor.from_pretrained(model_name_or_path)

    #LOAD IMAGE

    encoding = feature_extractor(images=image, return_tensors="pt")
    encoding.keys()

    pixel_values = encoding['pixel_values'].to(device)

    outputs = vit(pixel_values)
    logits = outputs.logits

    prediction = logits.argmax(-1)
    return prediction.item() #vit.config.id2label[prediction.item()]
