Overview of this book

This book will take you from the basics of neural networks to advanced implementations of architectures using a recipe-based approach. We will learn about how neural networks work and the impact of various hyper parameters on a network's accuracy along with leveraging neural networks for structured and unstructured data. Later, we will learn how to classify and detect objects in images. We will also learn to use transfer learning for multiple applications, including a self-driving car using Convolutional Neural Networks. We will generate images while leveraging GANs and also by performing image encoding. Additionally, we will perform text analysis using word vector based techniques. Later, we will use Recurrent Neural Networks and LSTM to implement chatbot and Machine Translation systems. Finally, you will learn about transcribing images, audio, and generating captions and also use Deep Q-learning to build an agent that plays Space Invaders game. By the end of this book, you will have developed the skills to choose and customize multiple neural network architectures for various deep learning problems you might encounter.

Face generation using a Deep Convolutional GAN

So far, we have seen how to generate new images. In this section, we will learn how to generate a new set of faces from an existing dataset of faces.

Getting ready

The approach we will be adopting for this exercise will be very similar to what we adopted in the Generating images using a Deep Convolutional GAN recipe:

  1. Collect a dataset that contains multiple face images.
  2. Generate random images at the start.
  1. Train a discriminator by showing it a combination of faces and random images, where the discriminator is expected to differentiate between an actual face image and a generated face image.
  2. Once the discriminator model is trained, freeze it and adjust the random images in such...
