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.

Summary

In this chapter, we have shown how CNNs can be used to learn from NLP data and how to train one from scratch using PyTorch. While the deep learning methodology is very different to the methodology used within RNNs, conceptually, CNNs use the motivation behind n-gram language models in an algorithmic fashion in order to extract implicit information about words in a sentence from the context of its neighboring words. Now that we have mastered both RNNs and CNNs, we can begin to expand on these techniques in order to construct even more advanced models.

In the next chapter, we will learn how to build models that utilize elements of both convolutional and recurrent neural networks and use them on sequences to perform even more advanced functions, such as text translation. These are known as sequence-to-sequence networks.
