Transformers for Natural Language Processing

By: Denis Rothman

Overview of this book

The transformer architecture has proved to be revolutionary in outperforming the classical RNN and CNN models in use today. With an apply-as-you-learn approach, Transformers for Natural Language Processing investigates in vast detail the deep learning for machine translations, speech-to-text, text-to-speech, language modeling, question answering, and many more NLP domains with transformers. The book takes you through NLP with Python and examines various eminent models and datasets within the transformer architecture created by pioneers such as Google, Facebook, Microsoft, OpenAI, and Hugging Face. The book trains you in three stages. The first stage introduces you to transformer architectures, starting with the original transformer, before moving on to RoBERTa, BERT, and DistilBERT models. You will discover training methods for smaller transformers that can outperform GPT-3 in some cases. In the second stage, you will apply transformers for Natural Language Understanding (NLU) and Natural Language Generation (NLG). Finally, the third stage will help you grasp advanced language understanding techniques such as optimizing social network datasets and fake news identification. By the end of this NLP book, you will understand transformers from a cognitive science perspective and be proficient in applying pretrained transformer models by tech giants to various datasets.

Applying Transformers to Legal and Financial Documents for AI Text Summarization

During the first six chapters, we explored the architecture of the Transformer and how to train transformers. We also implemented pretrained models that could perform downstream tasks with fine-tuning. Finally, in Chapter 6, Text Generation with OpenAI GPT-2 and GPT-3 Models, we discovered that OpenAI has begun to experiment with zero-shot models that require no fine-tuning.

The underlying concept of such an evolution relies on how transformers strive to teach a machine how to understand a language and express itself in a human-like manner. We have gone from training a model to teaching languages to machines.

Raffel et al. (2019) designed a transformer meta-model based on a simple assertion: every NLP problem can be represented as a text-to-text function. Every type of NLP task provides some kind of text context that generates some form of text response.

A text-to-text representation of any...
