Model Card for Model ID

A Vision Transformer (ViT) model fine-tuned for multi-class skin disease image classification.
It predicts 22 dermatological conditions, including acne, eczema, psoriasis, vitiligo, warts, and skin cancer.

This model is intended for research and educational purposes only and should not be used for real medical diagnosis.Provide a quick summary of what the model is/does. -->

Uses

Direct Use

Research in computer vision for dermatology
Educational use for ML students (classification, transfer learning, ViT)
Benchmarking ViT on multi-class medical datasets
Integration in multimodal pipelines (e.g., health chatbots, decision-support prototypes)

Downstream Use [optional]

Re-training or fine-tuning on clinical datasets
Transfer learning for fewer classes or specific diseases
Building explainability workflows (Grad-CAM, attention maps)

Out-of-Scope Use

This model must not be used:

For medical diagnosis or treatment
As a clinical decision-making tool
On patient images without proper consent
In high-stakes applications without domain-expert validation

Bias, Risks, and Limitations

Dataset contains varying image sources and qualities
Potential bias across skin tones, lighting, or acquisition devices
Some classes have limited examples, increasing risk of overfitting
No guarantee of generalization to real-world clinical data
Not validated by dermatologists or clinicians

Recommendations

Users should:

Avoid clinical deployment without proper validation
Re-train on demographically representative datasets
Interpret predictions cautiously

Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model. More information needed for further recommendations.

How to Get Started with the Model

Use the code below to get started with the model.

python

from transformers import AutoImageProcessor, AutoModelForImageClassification
from PIL import Image
import torch

processor = AutoImageProcessor.from_pretrained("LaurianeMD/vit-skin-disease")
model = AutoModelForImageClassification.from_pretrained("LaurianeMD/vit-skin-disease")

image = Image.open("your_image.jpg")
inputs = processor(images=image, return_tensors="pt")

with torch.no_grad():
    outputs = model(**inputs)
    logits = outputs.logits
    predicted_class_idx = logits.argmax(-1).item()

print("Predicted label:", model.config.id2label[predicted_class_idx])
