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 ...

Webwith more flexibility. Therefore, we use dice loss or Tversky index to replace CE loss to address the first issue. Only using dice loss or Tversky index is not enough since they are unable to address the dominating influence of easy-negative examples. This is intrin-sically because dice loss is actually a soft version of the F1 score.
