Overview of this book

Deep learning powers the most intelligent systems in the world, such as Google Voice, Siri, and Alexa. Advancements in powerful hardware, such as GPUs, software frameworks such as PyTorch, Keras, TensorFlow, and CNTK along with the availability of big data have made it easier to implement solutions to problems in the areas of text, vision, and advanced analytics. This book will get you up and running with one of the most cutting-edge deep learning libraries—PyTorch. PyTorch is grabbing the attention of deep learning researchers and data science professionals due to its accessibility, efficiency and being more native to Python way of development. You'll start off by installing PyTorch, then quickly move on to learn various fundamental blocks that power modern deep learning. You will also learn how to use CNN, RNN, LSTM and other networks to solve real-world problems. This book explains the concepts of various state-of-the-art deep learning architectures, such as ResNet, DenseNet, Inception, and Seq2Seq, without diving deep into the math behind them. You will also learn about GPU computing during the course of the book. You will see how to train a model with PyTorch and dive into complex neural networks such as generative networks for producing text and images. By the end of the book, you'll be able to implement deep learning applications in PyTorch with ease.

Deep Learning with Sequence Data and Text

In the last chapter, we covered how to handle spatial data using Convolution Neural Networks (CNNs) and also built image classifiers. In this chapter, we will cover the following topics:

  • Different representations of text data that are useful for building deep learning models
  • Understanding recurrent neural networks (RNNs) and different implementations of RNNs, such as Long Short-Term Memory (LSTM) and Gated Recurrent Unit (GRU), which power most of the deep learning models for text and sequential data
  • Using one-dimensional convolutions for sequential data

Some of the applications that can be built using RNNs are:

  • Document classifiers: Identifying the sentiment of a tweet or review, classifying news articles
  • Sequence-to-sequence learning: For tasks such as language translations, converting English to French
  • Time-series forecasting: Predicting...
