Autoencoders covered so far (except for CAEs) consisted only of a single-layer encoder and a single-layer decoder. However, it is possible for us to have multiple layers in encoder and decoder networks; using deeper encoder and decoder networks can allow the autoencoder to represent complex features. The structure so obtained is called a Stacked Autoencoder (Deep Autoencoders); the features extracted by one encoder are passed on to the next encoder as input. The stacked autoencoder can be trained as a whole network with an aim to minimize the reconstruction error, or each individual encoder/decoder network can be first pretrained using the unsupervised method you learned earlier, and then the complete network is fine-tuned. It has been pointed out that, by pretraining, also called Greedy layer-wise training, the results are better.

Overview of this book
Deep neural networks (DNNs) have achieved a lot of success in the field of computer vision, speech recognition, and natural language processing. This exciting recipe-based guide will take you from the realm of DNN theory to implementing them practically to solve real-life problems in the artificial intelligence domain.
In this book, you will learn how to efficiently use TensorFlow, Google’s open source framework for deep learning. You will implement different deep learning networks, such as Convolutional Neural Networks (CNNs), Recurrent Neural Networks (RNNs), Deep Q-learning Networks (DQNs), and Generative Adversarial Networks (GANs), with easy-to-follow standalone recipes. You will learn how to use TensorFlow with Keras as the backend. You will learn how different DNNs perform on
some popularly used datasets, such as MNIST, CIFAR-10, and Youtube8m. You will not only learn about the different mobile and embedded platforms supported by TensorFlow, but also how to set up cloud platforms for deep learning applications. You will also get a sneak peek at TPU architecture and how it will affect the future of DNNs.
By using crisp, no-nonsense recipes, you will become an expert in implementing deep learning techniques in growing real-world applications and research areas such as reinforcement learning,
GANs, and autoencoders.
