Web2 May 2024 · try only with SoftDiceLoss and see what is the result, BCE is probably correct try: score = (2*intersection+smooth)/ (m1.sum+m2.sum+smooth) I am not sure if you need probs=F.sigmoid: as I understand m1 and m2 are binary. 1 Like HariSumanth9 (Nandamuri Hari Naga Sumanth) May 21, 2024, 5:14pm #3 Thank you Web29 Nov 2024 · Brain image segmentation. With U-Net, domain applicability is as broad as the architecture is flexible. Here, we want to detect abnormalities in brain scans. The dataset, used in Buda, Saha, and Mazurowski ( 2024), contains MRI images together with manually created FLAIR abnormality segmentation masks. It is available on Kaggle.
