Overview of this book

Deep learning is driving the AI revolution, and PyTorch is making it easier than ever before for anyone to build deep learning applications. This PyTorch book will help you uncover expert techniques to get the most out of your data and build complex neural network models. The book starts with a quick overview of PyTorch and explores using convolutional neural network (CNN) architectures for image classification. You'll then work with recurrent neural network (RNN) architectures and transformers for sentiment analysis. As you advance, you'll apply deep learning across different domains, such as music, text, and image generation using generative models and explore the world of generative adversarial networks (GANs). You'll not only build and train your own deep reinforcement learning models in PyTorch but also deploy PyTorch models to production using expert tips and techniques. Finally, you'll get to grips with training large models efficiently in a distributed manner, searching neural architectures effectively with AutoML, and rapidly prototyping models using PyTorch and fast.ai. By the end of this PyTorch book, you'll be able to perform complex deep learning tasks using PyTorch to build smart artificial intelligence models.

Summary

In this chapter, we refreshed deep learning concepts such as layers, activation functions, and optimization schedules and how they contribute towards building varied deep learning architectures. We explored the PyTorch deep learning library, including some of the important modules, such as torch.nn, torch.optim, and torch.data, as well as tensor modules.

We then ran a hands-on exercise on training a deep learning model from scratch. We built a CNN for our exercise using PyTorch modules. We also wrote relevant PyTorch code to load the dataset, train and evaluate the model, and finally, make predictions from the trained model.

In the next chapter, we will explore a slightly more complex model architecture that involves multiple sub-models and use this type of hybrid model to tackle the real-world task of describing an image using natural text. Using PyTorch, we will implement such a system and generate captions for unseen images.
