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.

SimCLR architecture

SimCLR stands for Simple Contrastive Learning Architecture. This architecture is based on the paper "A Simple Framework for Contrastive Learning of Visual Representations", published by Geoffrey Hinton and Google Team. Geoffrey Hinton (just like Yann LeCun) is a co-recipient of the Turing Award for his work on Deep Learning. There are SimCLR and SimCLR2 versions. SimCLR2 is a larger and denser network than SimCLR. At the time of writing, SimCLR2 was the best architecture update available, but don't be surprised if there is a SimCLR3 soon that is even denser and better than the previous one.

The architecture has shown in relation to the ImageNet dataset that we can achieve 93% accuracy with just 1% of labels. This is a truly remarkable result considering that it took over 2 years and a great deal of effort from over 140,000 labelers (mostly graduate students) on Mechanical Turk to label ImageNet by hand. It was a massive undertaking carried out...
