Brain Hematoma Marker Recognition Using Multitask Learning: SwinTransformer and Swin-Unet

This paper proposes a method MTL-Swin-Unet which is multi-task learning using transformers for classification and semantic segmentation. For sprious-correlation problems, this method allows us to enhance the image representation with two other image representations: representation obtained by semantic segmentation and representation obtained by image reconstruction. In our experiments, the proposed method outperformed in F-value measure than other classifiers when the test data included slices from the same patient (no covariance shift). Similarly, when the test data did not include slices from the same patient (covariance shift setting), the proposed method outperformed in AUC measure.
