Advanced Deep Learning with Keras

Overview of this book

Recent developments in deep learning, including Generative Adversarial Networks (GANs), Variational Autoencoders (VAEs), and Deep Reinforcement Learning (DRL) are creating impressive AI results in our news headlines - such as AlphaGo Zero beating world chess champions, and generative AI that can create art paintings that sell for over $400k because they are so human-like. Advanced Deep Learning with Keras is a comprehensive guide to the advanced deep learning techniques available today, so you can create your own cutting-edge AI. Using Keras as an open-source deep learning library, you'll find hands-on projects throughout that show you how to create more effective AI with the latest techniques. The journey begins with an overview of MLPs, CNNs, and RNNs, which are the building blocks for the more advanced techniques in the book. You’ll learn how to implement deep learning models with Keras and TensorFlow 1.x, and move forwards to advanced techniques, as you explore deep neural network architectures, including ResNet and DenseNet, and how to create autoencoders. You then learn all about GANs, and how they can open new levels of AI performance. Next, you’ll get up to speed with how VAEs are implemented, and you’ll see how GANs and VAEs have the generative power to synthesize data that can be extremely convincing to humans - a major stride forward for modern AI. To complete this set of advanced techniques, you'll learn how to implement DRL such as Deep Q-Learning and Policy Gradient Methods, which are critical to many modern results in AI.

In this chapter, we've discussed how to disentangle the latent representations of GANs. Earlier on in the chapter, we discussed how InfoGAN maximizes the mutual information in order to force the generator to learn disentangled latent vectors. In the MNIST dataset example, InfoGAN uses three representations and a noise code as inputs. The noise represents the rest of the attributes in the form of an entangled representation. StackedGAN approaches the problem in a different way. It uses a stack of encoder-GANs to learn how to synthesize fake features and images. The encoder is first trained to provide a dataset of features. Then, the encoder-GANs are trained jointly to learn how to use the noise code to control attributes of the generator output.

In the next chapter, we will embark on a new type of GAN that is able to generate new data in another domain. For example, given an image of a horse, the GAN can perform an automatic transformation to an image of a zebra. The interesting...
