Model Overview

AttentionUNet for MRI Segmentation on the BraTS2023AdultGlioma dataset.

ATOMMIC: Training

To train, fine-tune, or test the model you will need to install ATOMMIC. We recommend you install it after you've installed latest Pytorch version.

pip install atommic['all']

Results

Evaluation

DICE = 0.8061 +/- 0.276 F1 = 0.1045 +/- 0.5801 HD95 = 5.119 +/- 5.411 IOU = 0.06959 +/- 0.4187

Limitations

This model was trained on the BraTS2023AdultGlioma dataset with stacked T1c, T1n, T2f, T2w images and might differ in performance compared to the leaderboard results.
