WebDec 3, 2024 · The problem is that your dice loss doesn't address the number of classes you have but rather assumes binary case, so it might explain the increase in your loss. You should implement generalized dice loss that accounts for all the classes and return the value for all of them. Something like the following: def dice_coef_9cat(y_true, y_pred ...
