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

GANs have been an active area of research and development in recent years, ever since their inception in 2014. This chapter was an exploration of the concepts behind GANs, including the components of GANs, namely, the generator and the discriminator. We discussed the architectures of each of these components and the overall schematic of a GAN model.

Next, we did a deep dive into a particular type of GAN – the DCGAN. With the help of an exercise, we built a DCGAN model from scratch using PyTorch. We used the MNIST dataset to train the model. The generator of the trained DCGAN model successfully generated realistic-looking fake images of handwritten digits after 10 epochs of training.

In the last section of this chapter, we explored another type of GAN, which is used for the task of image-to-image translation – the pix2pix model. Instead of working on just a pair of images, the pix2pix GAN model is architectured to generalize any image-to-image translation...
