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.

Generating images that can fool a neural network using adversarial attack

To understand how to perform an adversarial attack on an image, let's understand how regular predictions are made using transfer learning first and then we will figure out how to tweak the input image so that the image's class is completely different, even though we barely changed the input image.

Getting ready

Let's go through an example where we will try to identify the class of the object within the image:

  1. Read the image of a cat
  2. Preprocess the image so that it can then be passed to an inception network
  3. Import the pre-trained Inception v3 model
  4. Predict the class of the object present in the image
  5. The image will be predicted as a persian...
