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.

Building our first Deep Learning model

Now that we have built a basic NN, it's time to use our knowledge of creating an MLP to build a DL model. You will notice that the core framework will remain the same and is built upon the same foundation.

So, what makes it deep?

While the exact origins of who first used DL are often debated, a popular misconception is that DL just involves a really big NN model with hundreds or thousands of layers. While most DL models are big, it is important to understand that the real secret is a concept called backpropagation.

As we have seen, NNs such as MLPs have been around for a long time, and by themselves, they could solve previously unsolved classification problems such as XOR or give better predictions than traditional classifiers. However, they were still not accurate when dealing with large unstructured data such as images. In order to learn in high-dimensional spaces, a simple method called backpropagation is used, which gives feedback...
