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

How to Get Started with the Model
Model works with 1120×1120 patches. Use the following code snippet to load and use the model:
from transformers import AutoModel, AutoProcessor
from PIL import Image
model = AutoModel.from_pretrained("histai/SPIDER-breast-model", trust_remote_code=True)
processor = AutoProcessor.from_pretrained("histai/SPIDER-breast-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-breast dataset, a subset of the SPIDER dataset. The dataset includes:
| Class | Total Patches |
|---|---|
| Adenosis | 2899 |
| Benign phyllodes tumor | 4526 |
| Ductal carcinoma in situ (high-grade) | 5632 |
| Ductal carcinoma in situ (low-grade) | 5017 |
| Fat | 6286 |
| Fibroadenoma | 5243 |
| Fibrocystic changes | 5027 |
| Fibrosis | 6260 |
| Invasive non-special type carcinoma | 6142 |
| Lipogranuloma | 4941 |
| Lobular invasive carcinoma | 5102 |
| Malignant phyllodes tumor | 5271 |
| Necrosis | 5396 |
| Normal ducts | 4891 |
| Normal lobules | 5821 |
| Sclerosing adenosis | 3423 |
| Typical ductal hyperplasia | 5546 |
| Vessels | 5469 |
Total Counts:
- 92,892 central patches
- 984,924 total patches (including context patches)
- 921 total slides used for annotation
Results
| Organ | Accuracy | Precision | F1 Score |
|---|---|---|---|
| Breast | 0.902 | 0.896 | 0.897 |
