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 for Computer Vision

In Chapter 3, Diving Deep into Neural Networks, we built an image classifier using a popular Convolutional Neural Network (CNN) architecture called ResNet, but we used this model as a black box. In this chapter, we will cover the important building blocks of convolutional networks. Some of the important topics that we will be covering in this chapter are:

  • Introduction to neural networks
  • Building a CNN model from scratch
  • Creating and exploring a VGG16 model
  • Calculating pre-convoluted features
  • Understanding what a CNN model learns
  • Visualizing weights of the CNN layer

We will explore how we can build an architecture from scratch for solving image classification problems, which are the most common use cases. We will also learn how to use transfer learning, which will help us in building image classifiers using a very small dataset.
