WebIn this paper, we propose to use dice loss in replacement of the standard cross-entropy ob-jective for data-imbalanced NLP tasks. Dice loss is based on the Sørensen–Dice … WebAug 30, 2024 · The standard approach to fine tune BERT is to add a linear layer and softmax on the CLS token, and then training this new model using your standard CE loss [ 3 ], backpropagating through all layers of the model. This approach works well and is very explicit, but there are some problems with it.

WebNov 29, 2024 · A problem with dice is that it can have high variance. Getting a single pixel wrong in a tiny object can have the same effect as missing nearly a whole large object, thus the loss becomes highly dependent on the current batch.
