Hands-On Natural Language Processing with PyTorch 1.x

Become a proficient NLP data scientist by developing deep learning models for NLP and extract valuable insights from structured and unstructured data

Key Features

• Get to grips with word embeddings, semantics, labeling, and high-level word representations using practical examples
• Learn modern approaches to NLP and explore state-of-the-art NLP models using PyTorch
• Improve your NLP applications with innovative neural networks such as RNNs, LSTMs, and CNNs

Book Description

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.

What you will learn

• Use NLP techniques for understanding, processing, and generating text
• Understand PyTorch, its applications and how it can be used to build deep linguistic models
• Explore the wide variety of deep learning architectures for NLP
• Develop the skills you need to process and represent both structured and unstructured NLP data
• Become well-versed with state-of-the-art technologies and exciting new developments in the NLP domain
• Create chatbots using attention-based neural networks
