Overview of this book

In order to build robust deep learning systems, you’ll need to understand everything from how neural networks work to training CNN models. In this book, you’ll discover newly developed deep learning models, methodologies used in the domain, and their implementation based on areas of application. You’ll start by understanding the building blocks and the math behind neural networks, and then move on to CNNs and their advanced applications in computer vision. You'll also learn to apply the most popular CNN architectures in object detection and image segmentation. Further on, you’ll focus on variational autoencoders and GANs. You’ll then use neural networks to extract sophisticated vector representations of words, before going on to cover various types of recurrent networks, such as LSTM and GRU. You’ll even explore the attention mechanism to process sequential data without the help of recurrent neural networks (RNNs). Later, you’ll use graph neural networks for processing structured data, along with covering meta-learning, which allows you to train neural networks with fewer training samples. Finally, you’ll understand how to apply deep learning to autonomous vehicles. By the end of this book, you’ll have mastered key deep learning concepts and the different applications of deep learning models in the real world.

Understanding residual networks

Residual networks (ResNets, Deep Residual Learning for Image Recognition, https://arxiv.org/abs/1512.03385) were released in 2015, when they won all five categories of the ImageNet challenge that year. In Chapter 1, The Nuts and Bolts of Neural Networks, we mentioned that the layers of a neural network are not restricted to sequential order, but form a graph instead. This is the first architecture we'll learn, which takes advantage of this flexibility. This is also the first network architecture that has successfully trained a network with a depth of more than 100 layers.

Thanks to better weight initializations, new activation functions, as well as normalization layers, it's now possible to train deep networks. But, the authors of the paper conducted some experiments and observed that a network with 56 layers had higher training and testing...
