# SPIDER-Skin Model


### Model Description

SPIDER-skin model is a deep learning model trained for patch-level pathology classification, specifically for skin. It is part of the SPIDER dataset initiative, which provides a large, high-quality, multi-organ pathology dataset with expert-annotated labels.

If you would like to support, sponsor, or obtain a commercial license for the SPIDER data and models, please contact us at models@hist.ai.

### Model Sources

- **Repository:** [https://github.com/HistAI/SPIDER](https://github.com/HistAI/SPIDER)
- **Paper:** [SPIDER: A Comprehensive Multi-Organ Supervised Pathology Dataset and Baseline Models](https://arxiv.org/abs/2503.02876)

## How to Get Started with the Model

Model works with **1120×1120** patches.
Use the following code snippet to load and use the model:

```python
from transformers import AutoModel, AutoProcessor
from PIL import Image

model = AutoModel.from_pretrained("histai/SPIDER-skin-model", trust_remote_code=True)
processor = AutoProcessor.from_pretrained("histai/SPIDER-skin-model", trust_remote_code=True)

image = Image.open("path_to_image.png")
inputs = processor(images=image, return_tensors="pt")
outputs = model(**inputs)
print(outputs.predicted_class_names)
```


### Training Data

The model is trained on the [SPIDER-skin](https://huggingface.co/datasets/histai/SPIDER-skin) dataset, a subset of the SPIDER dataset. The dataset includes:
