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.

Chapter 2: Getting Started with PyTorch 1.x for NLP

PyTorch is a Python-based machine learning library. It consists of two main features: its ability to efficiently perform tensor operations with hardware acceleration (using GPUs) and its ability to build deep neural networks. PyTorch also uses dynamic computational graphs instead of static ones, which sets it apart from similar libraries such as TensorFlow. By demonstrating how language can be represented using tensors and how neural networks can be used to learn from NLP, we will show that both these features are particularly useful for natural language processing.

In this chapter, we will show you how to get PyTorch up and running on your computer, as well as demonstrate some of its key functionalities. We will then compare PyTorch to some other deep learning frameworks, before exploring some of the NLP functionality of PyTorch, such as its ability to perform tensor operations, and finally demonstrate how to build a simple neural...
