Hands-On Natural Language Processing with PyTorch 1.x

By: Thomas Dop

Overview of this book

In the internet age, where an increasing volume of text data is generated daily from social media and other platforms, being able to make sense of that data is a crucial skill. With this book, you’ll learn how to extract valuable insights from text by building deep learning models for natural language processing (NLP) tasks. Starting by understanding how to install PyTorch and using CUDA to accelerate the processing speed, you’ll explore how the NLP architecture works with the help of practical examples. This PyTorch NLP book will guide you through core concepts such as word embeddings, CBOW, and tokenization in PyTorch. You’ll then learn techniques for processing textual data and see how deep learning can be used for NLP tasks. The book demonstrates how to implement deep learning and neural network architectures to build models that will allow you to classify and translate text and perform sentiment analysis. Finally, you’ll learn how to build advanced NLP models, such as conversational chatbots. By the end of this book, you’ll not only have understood the different NLP problems that can be solved using deep learning with PyTorch, but also be able to build models to solve them.

While we have shown our sequence-to-sequence model to be effective at performing language translation, the model we trained from scratch is not a perfect translator by any means. This is, in part, due to the relatively small size of our training data. We trained our model on a set of 30,000 English/German sentences. While this might seem very large, in order to train a perfect model, we would require a training set that's several orders of magnitude larger.

In theory, we would require several examples of each word in the entire English and German languages for our model to truly understand its context and meaning. For context, the 30,000 English sentences in our training set consisted of just 6,000 unique words. The average vocabulary of an English speaker is said to be between 20,000 and 30,000 words, which gives us an idea of just how many examples sentences we would need to train a model that performs perfectly. This is probably why the most accurate translation...
