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.

Building a sequence-to-sequence model for text translation

In order to build our sequence-to-sequence model for translation, we will implement the encoder/decoder framework we outlined previously. This will show how the two halves of our model can be utilized together in order to capture a representation of our data using the encoder and then translate this representation into another language using our decoder. In order to do this, we need to obtain our data.

Preparing the data

By now, we know enough about machine learning to know that for a task like this, we will need a set of training data with corresponding labels. In this case, we will need sentences in one language with the corresponding translations in another language. Fortunately, the Torchtext library that we used in the previous chapter contains a dataset that will allow us to get this.

The Multi30k dataset in Torchtext consists of approximately 30,000 sentences with corresponding translations in multiple languages...
