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.

Performing vector arithmetic on generated images

Now that we understand that the latent vector representations play a key part in changing the outcome of the generated image, let's further build our intuition with images that have a certain face alignment.

Getting ready

The strategy that we'll adopt to perform vector arithmetic on a generated image is as follows:

  1. Generate three images that are based on the random noise of 100 vector values
  2. Ensure that two of the three images have generated faces that look to the left, and that one looks to the right
  3. Calculate a new vector that is the sum of images that are aligned in the same direction, which is further subtracted from the image that is aligned in the opposite direction...
