Generative Adversarial Networks Projects

By: Kailash Ahirwar

Overview of this book

Generative Adversarial Networks (GANs) have the potential to build next-generation models, as they can mimic any distribution of data. Major research and development work is being undertaken in this field since it is one of the rapidly growing areas of machine learning. This book will test unsupervised techniques for training neural networks as you build seven end-to-end projects in the GAN domain. Generative Adversarial Network Projects begins by covering the concepts, tools, and libraries that you will use to build efficient projects. You will also use a variety of datasets for the different projects covered in the book. The level of complexity of the operations required increases with every chapter, helping you get to grips with using GANs. You will cover popular approaches such as 3D-GAN, DCGAN, StackGAN, and CycleGAN, and you’ll gain an understanding of the architecture and functioning of generative models through their practical implementation. By the end of this book, you will be ready to build, train, and optimize your own end-to-end GAN models at work or in your own projects.

A Keras implementation of StackGAN

The Keras implementation of StackGAN is divided into two parts: Stage-I and Stage-II. We will implement these stages in the following sections.

Stage-I

A Stage-I StackGAN contains both a generator network and a discriminator network. It also has a text encoder network and a Conditional Augmentation network (CA network), which are explained in detail in the following section. The generator network gets the text conditioning variable (), along with a noise vector (x). After a set of upsampling layers, it produces a low-resolution image with dimensions of 64x64x3. The discriminator network takes this low-resolution image and tries to identify whether the image is real or fake. The generator...
