Fine-Tuning BERT Models

In Chapter 2, Getting Started with the Architecture of the Transformer Model, we defined the building blocks of the architecture of the original Transformer. Think of the original Transformer as a model built with LEGO^® bricks. The construction set contains bricks such as encoders, decoders, embedding layers, positional encoding methods, multi-head attention layers, masked multi-head attention layers, post-layer normalization, feed-forward sub-layers, and linear output layers.

The bricks come in various sizes and forms. You can spend hours building all sorts of models using the same building kit! Some constructions will only require some of the bricks. Other constructions will add a new piece, just like when we obtain ...
