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:

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
