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.
