Overview of this book

Building and implementing deep learning (DL) is becoming a key skill for those who want to be at the forefront of progress.But with so much information and complex study materials out there, getting started with DL can feel quite overwhelming. Written by an AI thought leader, Deep Learning with PyTorch Lightning helps researchers build their first DL models quickly and easily without getting stuck on the complexities. With its help, you’ll be able to maximize productivity for DL projects while ensuring full flexibility – from model formulation to implementation. Throughout this book, you’ll learn how to configure PyTorch Lightning on a cloud platform, understand the architectural components, and explore how they are configured to build various industry solutions. You’ll build a neural network architecture, deploy an application from scratch, and see how you can expand it based on your specific needs, beyond what the framework can provide. In the later chapters, you’ll also learn how to implement capabilities to build and train various models like Convolutional Neural Nets (CNN), Natural Language Processing (NLP), Time Series, Self-Supervised Learning, Semi-Supervised Learning, Generative Adversarial Network (GAN) using PyTorch Lightning. By the end of this book, you’ll be able to build and deploy DL models with confidence.

Summary

GAN is a powerful method for generating not only images but also paintings, and even 3D objects (using newer variants of a GAN). We saw how, using a combination of discriminator and generator networks (each with five convolutional layers), we can start with random noise and generate an image that mimics real images. The play-off between the generator and discriminator keeps producing better images by minimizing the loss function and going through multiple iterations. The end result is fake pictures that never existed in real life.

It's a powerful method, and there are concerns about its ethical use. Fake images and objects can be used to defraud people; however, it also creates endless new opportunities. For example, imagine looking at a picture of fashion models while shopping for a new outfit. Instead of relying on endless image shoots, using a GAN (and DCGAN), you can generate realistic pictures of models with all body types, sizes, shapes, and colors, helping both...
