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.

In this chapter, we went through some advanced theory. The principle of compositionality is not an intuitive concept. The principle of compositionality means that the transformer model must understand every part of the sentence to understand the whole sentence. This involves logical form rules that will provide links between the sentence segments.

The theoretical difficulty of sentiment analysis requires a large amount of transformer model training, powerful machines, and human resources. Although many transformer models are trained for many tasks, they often require more training for specific tasks.

We tested RoBERTa-large, DistilBERT, MiniLM-L12-H384-uncased, and the excellent BERT-base multilingual model. We found that some provided interesting answers but required more training to solve the SST sample we ran on several models.

Sentiment analysis requires a deep understanding of a sentence and extraordinarily complex sequences. It made sense to try RoBERTa-large...
