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']
How to Use this Model

Results
Evaluation
DICE = 0.9359 +/- 0.1334 F1 = 0.6735 +/- 0.782 HD95 = 3.55 +/- 2.162 IOU = 0.5279 +/- 0.6518
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.
