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. WebAnd I think the problem with your loss function is the weights are not normalized. I think a normalized weights should be what you want.
