# MahimaTayal123/DR-Classifier

This model is a fine-tuned version of [google/vit-base-patch16-224-in21k](https://huggingface.co/google/vit-base-patch16-224-in21k) on an unknown dataset.
It achieves the following results on the evaluation set:
- Train Loss: 0.2187
- Validation Loss: 0.2654
- Train Accuracy: 0.9420
- Epoch: 5

## Model description

    This model leverages the Vision Transformer (ViT) architecture to classify retinal images for early detection of Diabetic Retinopathy (DR). The fine-tuned model improves accuracy and generalization on medical imaging datasets.


## Intended uses & limitations

### Intended Uses:
- Medical diagnosis support for Diabetic Retinopathy  
- Research applications in ophthalmology and AI-based healthcare  

### Limitations:
- Requires high-quality retinal images for accurate predictions  
- Not a substitute for professional medical advice; should be used as an assistive tool  


## Training and evaluation data

    The model was trained on a curated dataset containing labeled retinal images. The dataset includes various severity levels of Diabetic Retinopathy, ensuring robustness in classification.
