Hey guys, I just implemented the generalised dice loss (multi-class version of dice loss), as described in ref : (my targets are defined as: (batch_size, image_dim1, image_dim2, image_dim3, nb_of_classes)) def generalized_dice_loss_w(y_t...

dice_loss_for_keras.py. """. Here is a dice loss for keras which is smoothed to approximate a linear (L1) loss. It ranges from 1 to 0 (no error), and returns results similar to binary crossentropy. """. # define custom loss and metric functions. from keras import backend as K.

My implementation of dice is based on this: https://github.com/Lasagne/Recipes/issues/99. y_true has shape (batch,m,n,1) and y_pred has shape ( ...

It really works fine for my unbalanced dataset (from histology with small tumor formations vs. huge normal tissue). For me, the normal dice loss ...

02.07.2021 · The Generalized Wasserstein Dice Loss (GWDL) is a loss function to train deep neural networks for applications in medical image multi-class segmentation. The GWDL is a generalization of the Dice loss and the Generalized Dice loss that can tackle hierarchical classes and can take advantage of known relationships between classes. Installation

Generalized Wasserstein Dice Loss [1] in PyTorch. Optionally, one can use a weighting method for the: class-specific sum of errors similar to the one used: in the generalized Dice Loss [2]. For this behaviour, please use weighting_mode='GDL'. The exact formula of the Wasserstein Dice loss in this case: can be found in the Appendix of [3 ...
