Alzheimers Detection using MRI Scans 🏥

Getting Started

git clone <url>
cd alzheimers-fastai
tar -xf dataset.tar.xz
pip install -r requirements.txt
python alzheimers_pred.py

Use data.tar.xz only if using 5-Fold-Cross-Validation

OR

OR

Use the pretrained model from models/alzheimers.pt

Approach 📑

  • Use of OASIS dataset considering the three scan angles as individual truth thus expanding the dataset by 3x.
  • Transfer Learning on DenseNet201
  • Trained for 5+25 epochs

More epochs, data_transforms may improve results.

DenseNet201

Results ✨

  • Accuracy of ~ 81%.
