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.

Gender classification of the person in an image using CNNs

To understand some of the limitations of CNNs, let's go through an example where we try to identify whether the given image contains the image of a cat or a dog.

Getting ready

We will gain an intuition of how a CNN predicts the class of object present in the image through the following steps:

  • A convolution filter is activated by certain parts of the image:
    • For example, certain filters might activate if the image has a certain pattern—it contains a circular structure, for example
  • A pooling layer ensures that image translation is taken care of:
    • This ensures that even if an image is big, over an increased number of pooling operations, the size of the...
