Instructions and Navigation
All of the code is organized into folders. Each folder starts with CH followed by the chapter number. For example, CH01.
The notebooks are then organized as follows: ch01_attention_mechanism_variations.ipynb, where ch01 indicates the chapter
and attention_mechanism_variations what is done in the notebook.
