WebJun 28, 2024 · BERT-base has 12 layers of Transformer encoder blocks and each layer has 12 self-attention heads; there is a total of 144 self-attention heads in BERT-base. Despite its success in various NLP tasks, BERT sometimes overfits when the training dataset is small due to overparameterization. WebAll BERT-based architectures have a self-attention block followed by a block of intermediate layers as the basic building component. However, a strong justification for the inclusion of these intermediate layers remains missing in the literature.

WebImagine in bert you have 144 self attention block (12 in each layer). If there is no FFN all will act the same and similar. Adding FFN make each of them behave like a separate small model that can be trained (get parameters). Then the whole process become like training a "stacked ensemble learning" where each model get different weight.
