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 final chapter of the book, we focused on both abstracting out the noisy details involved in model training code and the core components to facilitate the rapid prototyping of models. As PyTorch code can often be cluttered with a lot of such noisy detailed code components, we looked at some of the high-level libraries that are built on top of PyTorch.

First, we explored fast.ai, which enables PyTorch models to be trained in fewer than 10 lines of code. In the form of an exercise, we demonstrated the effectiveness of training a handwritten digit classification model using fast.ai. We used one of fast.ai's modules to load the dataset, another module to train and evaluate a model, and—finally—another module to interpret the trained model behavior.

Next, we looked at PyTorch Lightning, which is another high-level library built on top of PyTorch. We did a similar exercise of training a handwritten digit classifier. We demonstrated the code layout...
