Kickstart your NLP journey by exploring BERT and its variants such as ALBERT, RoBERTa, DistilBERT, VideoBERT, and more with Hugging Face's transformers library
Key FeaturesExplore the encoder and decoder of the transformer modelBecome well-versed with BERT along with ALBERT, RoBERTa, and DistilBERTDiscover how to pre-train and fine-tune BERT models for several NLP tasksBook DescriptionBERT (bidirectional encoder representations from transformer) has revolutionized the world of natural language processing (NLP) with promising results. This book is an introductory guide that will help you get to grips with Google's BERT architecture. With a detailed explanation of the transformer architecture, this book will help you understand how the transformer’s encoder and decoder work.
You’ll explore the BERT architecture by learning how the BERT model is pre-trained and how to use pre-trained BERT for downstream tasks by fine-tuning it for NLP tasks such as sentiment analysis and text summarization with the Hugging Face transformers library. As you advance, you’ll learn about different variants of BERT such as ALBERT, RoBERTa, and ELECTRA, and look at SpanBERT, which is used for NLP tasks like question answering. You'll also cover simpler and faster BERT variants based on knowledge distillation such as DistilBERT and TinyBERT. The book takes you through MBERT, XLM, and XLM-R in detail and then introduces you to sentence-BERT, which is used for obtaining sentence representation. Finally, you'll discover domain-specific BERT models such as BioBERT and ClinicalBERT, and discover an interesting variant called VideoBERT.
By the end of this BERT book, you’ll be well-versed with using BERT and its variants for performing practical NLP tasks.

The preface states the book is for: " [...] for NLP professionals and data scientists looking to simplify NLP tasks to enable efficient language understanding using BERT."
And that, "A basic understanding of NLP concepts and deep learning is required to get the most out of this book."
To that end, if you tick both of the above boxes, then this book is DEFINITELY for you.
Pros: 1) Style The author writes in a conversational manner which makes it incredibly easy to follow along; it is no easy feat to write about complex subjects in an engaging manner.
2) Examples The code examples are easy to follow and implement. Additionally, the repo on github provides further explanations.
3) Range What was most illuminating was the shear number of potential use cases presented (i.e., domain-specific BERT models, BERT in languages other than English, VideoBERT, and BART.
Con: 1) Examples The only critique I have is the datasets used are toy data sets. For instance, the example for "Fine-tuning BERT for sentiment analysis" in chapter 3 makes use of the IMDB dataset which is loaded through the Hugging Face dataset API. Since this is a toy dataset, it is already in the format BERT prefers. To that end, it would be incredibly useful to provide examples of how to prepare real datasets for analysis using BERT.
In conclusion, if you are looking for a book which provides an overview, potential use cases, and examples of how to implement BERT, then this book is for you.
This book is a good entry point into modern solutions for different NLP tasks. I think this book is great for readers, who are familiar with neural networks in other fields and want to know what is state of the art in NLP now. The book begins with an exhaustive description of the building blocks of transformers and BERT, then different use cases are discussed.
I would recommend this book as the first book to start the journey on BERT models for researchers and developers who are already familiar with NLP and deep learning in general but like to learn BERT for problem solving
